Abstract:
Abstract The Radio over Fiber (RoF) system has emerged out a promising solution to the last mile connectivity along with higher data rates making it the preference for future communication networks. But fiber nonlinearities induce crosstalk and degrade the performance of the system. This paper presents a simulative investigation & comparison of Mach Zehender Modulator (MZM) and Optical Phase Modulator (OPM) including the effects of Self Phase Modulation. A single channel RoF system has been designed using MZM and OPM respectively. The model is analyzed for different ranges of dispersion and input channel power. It is observed that as the dispersion modulus increases the SPM induced pulse broadening also increases. The pulse broadening also increases with increase in the channel input power. Further it is revealed that MZM offers 0.3 dB more channel output power compared to OPM when dispersion is increased from 2 to 10 ps/nm/km. With the increase in channel input power from 10 to 17.5 dBm, OPM suppress SPM effects better than MZM and provides 2 dB more channel output power.

Abstract:
Methods for Estimation of Optical Fiber Non-Linearity Using Self-Phase Modulation Effect Due to ever increasing channel density in WDM systems the nonlinear optical effects in fibers become a limiting factor for the high-speed data transmission, which necessitates determination of such important characteristic as the coefficient of optical nonlinearity. To measure it, two methods are proposed: continuous wave self-phase modulation (CW-SPM) and pulse phase self-modulation (P-SPM). The research work has been carried out both in the form of calculations and experimentally, taking as wavelength the central one from the third optical transparency window, λ = 1550 nm. Based on the OptSim 5.2 simulations and experimental results, the sought-for nonlinear coefficients have been calculated. In the paper, comparative analysis and estimation of the results are performed for two different optical fibers.

Abstract:
In this paper, Self Phase Modulation (SPM) in chalcogenide As2Se3glass Photonic Crystal Fiber (PCF) is numerically studied by combining the fully vectorial effective index method (FVEIM) and Split Step Fourier Method (SSFM). The FVEIM is used to calculate the variation of effective refractive index of guided mode (neff), effective area (Aeff), dispersion and non-linear coefficient (γ) with wavelength for different designs of chalcogenide As2Se3PCF. The FVEIM solves the vector wave equations and SSFM solves non linear Schrödinger Equation (NLSE) for the different designing parameter of As2Se3PCF. In case of Self Phase Modulation (SPM), spectral width of the obtained output pulse at d/Λ=0.7 is 1.5 times greater than width of the output pulse obtained at d/L=0.3 using SSFM. Thus we can get the desired spectral broadening just by tailoring the design parameters of the PCF.

Abstract:
A scheme to achieve 40Gb/s all-optical 3R-regeneration through cross-phase modulation and self-phase modulation is studied in this paper. The core of the scheme is to use ultra-highly nonlinear photonic crystal fiber as the Mach-Zehnder interference of one arm. Length of the photonic crystal fiber at the arm is adjusted after calculation so as to make the signal light through the arm produce nonlinear phase shift of by means of XPM effect, then mutual interference between the resulting light and the optical signal at the other arm is generated and the noise interfusing the system is eliminated to make the signal be regenerated. Furthermore, self-phase modulation effect of the fiber is applied to make further optimization of the signal, with Optisystem for simulation experiment.

Abstract:
The main limitation factor of high capacity multichannel DWDM (Dense Wavelength Division Multiplexing) systems are fiber nonlinear effects. The optical signal is severely degraded due to fiber nonlinear effects also known as Kerr fiber nonlinearity. Nonlinear effects under investigation are self-phase modulation (SPM) and cross-phase modulation (XPM). There are several methods to compensate these nonlinear distorts, some less or more effective. Nonlinear distort due to SPM and XPM can be effectively mitigated through implementation of optical DQPSK modulation over commonly used intensity modulation known as OOK (On-Off Keying). This paper presents a numerical simulation model of 1.28 Tbps DWDM system with optical DQPSK modulation. We present several scenarios and methods to mitigate fiber nonlinear effects including Fractional Fourier Transform (FrFT). Linear and nonlinear effects are considered together, so we implement the inline FrFT module in the optical domain which causes a time-frequency plane rotation to mitigate combined linear and nonlinear effects. The performance of proposed 1.28 Tbps DQPSK modulated DWDM system is evaluated in term of bit error rate (BER) and Q factor value.

Abstract:
Self-phase modulation (SPM) induces a varying refractive index of the medium due to the optical Kerr effect. The optical waves propagation (OWP) in a medium with SPM occupied a remarkable area of research in the literature. A model equation to describe OWP in the absence of SPM was proposed very recently by Biswas–Arshed equation (BAE). This work is based on constructing the solutions that describe the waves which arise from soliton-periodic wave collisions. A variety of geometric optical wave structures are observed. Here, a transformation that allows to investigate the multi-geometric structures of OW’s result from soliton-periodic wave collisions is introduced. Chirped, conoidal, breathers, diamond and W-shaped optical waves are shown to propagate in the medium in the absence of SPM. The exact solutions of BAE are obtained by using the unified method, which was presented recently. We mention that the results found here, are completely new.

Full text
Abstract:
We compare the performances of three previously proposed methods to reduce the peak-to-average power ratio (PAPR) of the carrier-suppressed optical single-sideband (OSSB-SC) signal. PAPR of OSSB-SC signal becomes high due to the peaky Hilbert-transformed signal which is used for spectral suppression. Nonlinear phase shifts induced by high PAPR degrade OSSB-SC signal during fiber transmission. Previously, we proposed peak folding, peak clipping, and high-pass Hilbert transform methods to reduce the PAPR of OSSB-SC modulation. In this study, we numerically compare the effectiveness of proposed methods in a 10 Gbit/s non-return-to-zero (NRZ)-coded 100-km single-channel transmission link. Due to the reduced PAPR, peak folding and peak clipping can increase the self-phase modulation (SPM) threshold of the studied system by 2.40 dB and 2.63 dB respectively. The high-pass Hilbert transform method improves the SPM threshold by more than 9 dB.

Abstract:
In this paper, we investigate the inhomogeneous higher-order nonlinear Schr¨odinger (NLS) equation governing the femtosecond optical pulse propagation in inhomogeneous fibers using gauge transformation and generate bright soliton solutions from the associated linear eigenvalue problem. We observe that the amplitude of the bright solitons depends on the group velocity dispersion (GVD) and the self-phase modulation (SPM) while its velocity is dictated by the third-order dispersion (TOD) and GVD. We have shown how the interplay between GVD, SPM, and TOD can be profitably exploited to change soliton width, amplitude (intensity), shape, phase, velocity, and energy for an effective femtosecond soliton management. The highlight of our paper is the identification of ‘optical similaritons’ arising by virtue of higher-order effects in the femtosecond regime.

Nesta dissertaÃÃo foi estudada a aplicaÃÃo do filtro AcÃstico-Ãptico SintonizÃvel (AOTF), com a ModulaÃÃo de Pulsos por PosiÃÃo (PPM), objetivando implementar, utilizando o mÃtodo de Runge-Kutta de 4a ordem, portas lÃgicas (OR-OU e AND-E) Ãpticas operando com pulsos de luz ultracurtos (2ps). Neste trabalho à investigado o desempenho das portas considerando vÃrios comprimentos do filtro ( L) que integra a sua estrutura interna, com o intuito de obter o comprimento de filtro mais adequado para uma operaÃÃo satisfatÃria, em regime dispersivo, nÃo linear, sem perdas e com modulaÃÃo de fase cruzada (XPM). Esta investigaÃÃo à realizada em duas situaÃÃes: primeiramente, sÃo considerados filtros com automodulaÃÃo de fase (SPM) e GVD (dispersÃo da velocidade de grupo). Em um segundo momento, as mesmas portas sÃo obtidas com efeitos SPM, XPM e GVD agindo juntos no AOTF. Foi observado que para pulsos do tipo sÃliton, os efeitos da dispersÃo, da nÃo linearidade e da modulaÃÃo de fase cruzada exercem juntos uma forte influÃncia na propagaÃÃo do mesmo, provocando a quebra do pulso na saÃda do dispositivo quando utilizamos um comprimento maior para os filtros. Para dispositivos mais curtos, o pulso chaveado apresentou compressÃes e alargamentos temporais e espectrais, bem comodeslocamentos temporais nos dois modo de propagaÃÃo (TE e TM). ApÃs a escolha de um comprimento de filtro adequado, foi selecionado um deslocamento temporal Ãtimo a ser aplicado nos pulsos de entrada para conseguirmos, na saÃda da porta lÃgica, deslocamentos temporais satisfatÃrios (acertos) na aplicaÃÃo da modulaÃÃo PPM. Em seguida, introduzimos fases em um dos pulsos de entrada (TM), provocando um defasamento entre os pulsos TE e TM, reduzindo ainda mais a margem de erro PPM de operaÃÃo das portas. Finalmente, ao analisarmos as fases aplicadas no pulso TM (0 a 2), definirmos o melhor Ãngulo de fase para que as portas operem na regiÃo de acerto da modulaÃÃo PPM.
In this dissertation it was studied the application of the Acoustic Optical Tunable Filter (AOTF), with Pulse Position Modulation (PPM), aiming at to implement, using the method of Runge-Kutta of 4a order, logical gates (OR and AND) optical operating with pulses of light ultra shorts (2ps). In this work the acting of the gates is investigated, considering several lengths of the filter (  L) that integrates your internal structure, with the intention of obtaining the length of more appropriate filter for a satisfactory operation, in dispersion regime, nonlinear, without losses and with Cross Phase Modulation (XPM). This investigation is accomplished in two situations: firstly, filters are considered with Self Phase Modulation (SPM) and GVD (group-velocity dispersion). In a second moment, the same gates are obtained with effects SPM, XPM and GVD, acting together in AOTF. It was observed that for pulses of the type soliton, the effects of the dispersion, of the nonlinearity and of the cross phase modulation exercise together a strong influences in the propagation of the same, provoking the break of the pulse in the exit of the device when we used a larger length for the filters. For shorter devices, the switched pulse presented temporary and spectral compression and spread, as well as, displacement in the time in the two propagation modes (TE and TM). After the choice of a length of appropriate filter, a great temporary displacement was selected to be applied in the input pulses for us to get, in the exit of the logical gate, satisfactory temporary displacements (successes) in the application of the PPM modulation. Soon after, we introduced phases in one of the entrance pulses (TM), provoking a phase displacement among TE and TM pulses, still reducing more the margin of error PPM of operation of the gates. Finally, to the we analyze the applied phases in the pulse TM (0 to 2), we defined the best phase angle for the gates to operate in the success area of the PPM modulation.

Self-phase modulation (SPM) creates a power and fiber-length dependent spectral broadening that reduces signal-to-noise ratio in free-space laser communication systems which use a fiber to connect their transmitter's high-power optical amplifier to its telescope optics. The effects of SPM can be mitigated by using a phase modulator to down-chirp pulses before passing through the receiver's matched filter. This thesis tests and evaluates a new SPM compensation technique-applying a phase modulation determined from a measurement of the SPM-distorted waveform's optical intensity-and benchmarks it against sinusoidal phase modulation compensation. The spectra and throughput of the compensated signal are calculated and measured to determine the effectiveness of the new technique. It is found that the two techniques perform within 0.2 dB of each other for fiber lengths less than three times the nonlinear length, and it is expected that the new technique will outperform sinusoidal phase modulation for greater fiber lengths.

Abstract:
In this work, two optical devices, organic photovoltaics (OPVs) and optical fibers, are introduced. Each of these devices have performance drawbacks. The major drawbacks of organic photovoltaics is their low absorption rate due to bandgap mismatch with the solar spectrum as well as poor charge carrier mobility and short exciton diffusion length. In order to overcome some of these drawbacks and increase the efficiency of OPVs, we use plasmonic gold nanoparticles (AuNPs). We report 30% increase in the efficiency of bulk-heterojunction OPV after incorporation of 50 nm AuNPs. The optical, electrical, and thermal impacts of AuNPs on the performance of PVs have been investigated experimentally and using Lumerical Solutions and COMSOL Multiphysics® simulation packages. The major contributions of AuNPs is causing near field enhancement and increasing the absorption of the structure by 65%, decreasing the extracted carrier density by quenching the excitons, changing the workfunction of the structure, as well as increasing the temperature of their surrounded medium when exited at their plasmon resonance frequency. Furthermore, one of the challenges in devices made from optical fibers such as wavelength division multiplexing systems, is self-phase modulation (SPM) which is a nonlinear phenomenon. We introduce a novel method to remove the SPM in liquid core optical fibers (LCOF) using nonlinear organic chromophores with a negative third-order susceptibility. The idea of this work is to eliminate the effective nonlinear refractive index that the optical pulses are experiencing while propagating through the LCOF. Further, a novel method is introduced to characterize the third-order optical nonlinear susceptibility of organic chromophores in LCOF system. The presented method is simple, and can be extended to the characterization of other nanoscale particles such as quantum dots and plasmonic metal nanoparticles in solutions. Finally, a convenient method is presented that enables researchers to investigate the mechanisms behind photobleaching of various materials. The photostability of materials is of great importance for their acceptance in commercial systems such as organic photovoltaics, electro-optic (EO) modulators and switches, etc. This method is based on the simultaneous detection of different signals such as second-, and third-harmonic generations as well as two-, and three-photon excitation fluorescence using multi-photon microscopy.

Abstract:
Formatos de modulação com capacidade de ajuste às condições variáveis de propagação são de interesse para uso em redes ópticas reconfiguráveis. Alterações nos níveis de potência e no mapa de dispersão afetam o desempenho de sistemas de transmissão, limitando o alcance e a capacidade de reconfiguração da rede. Fornecer capacidade de ajuste dinâmico ao sinal transmitido, sem usar sistemas complexos de modulação ou de compensação variável de dispersão, é uma solução eficaz para se obter rendimento ótimo nas diversas condições de propagação na rede. Esta característica também é útil na instalação de redes convencionais, poupando tempo e reduzindo custos. Neste trabalho é proposto o formato de modulação NRZ com gorjeio sincronizado com o sinal como alternativa para sobrepujar as limitações impostas pelas redes reconfiguráveis. O sistema proposto tem o atrativo de permitir, além da capacidade de adaptação, a possibilidade de integração dos componentes ópticos do modulador num mesmo substrato. O desempenho do formato de modulação proposto foi analisado em diversas condições de propagação para sistemas a 10 Gbit/s, tanto em sistemas ponto-a-ponto como de longas distâncias. Esta análise foi feita por meio de modelagem matemática, simulações numéricas e experimentos em laboratório. Foi demonstrada a capacidade de ajuste a diversos mapas de dispersão e seus limites, bem como a compensação de efeitos da automodulação de fase causados por alterações no nível da potência do sinal.
Modulation formats with adjustment capability to the variable propagation conditions are of interest in reconfigurable optical networks. Changes in optical power levels and dispersion compensation map affect the transmission system performance, limiting the range and the network reconfiguration capability. To provide dynamical adjustment capability to the transmitted signal, using neither complex modulation systems nor variable dispersion compensation, is an effective solution to obtain optimal performance within the diverse network propagation conditions. This characteristic is also useful during conventional networks installation, saving time and reducing costs. In this work it is proposed the NRZ modulation format with signal synchronized chirp as an alternative to overcome the limitations imposed by the reconfigurable networks. The proposed system has the benefit of allowing, more than adaptation capability, the possibility of integration of the optical modulator\'s components in the same substrate. The proposed modulation format was analyzed under diverse propagation conditions for 10 Gbit/s, in point-to-point as well as long-haul systems. This analyses war performed by mathematical modeling, numerical simulations and laboratorial experiments. It was demonstrated the adjustment capability for diverse dispersion compensation maps and its limits as well as the compensation of the self-phase modulation effects due to changes in optical power levels.

Abstract:
La course vers les impulsions ultra-courtes et énergétiques est en plein essor avec le développement de nombreuses applications. Dans ce manuscrit, plusieurs méthodes de réduction de la durée d'impulsion énergétique sont étudiées. La mise en oeuvre d’un système de post-compression basé sur le principe de SPM-NER dans une lame de silice a tout d'abord permis de produire, à partir d'impulsions de 50 fs, des impulsions de 16 fs-5mJ. Dans une seconde partie, nous proposons une nouvelle méthode de post-compression efficace basée sur l'ionisation d'un gaz rare dans un capillaire creux. Cette technique a permis d'obtenir à la fois des impulsions ultra-courtes et des énergies importantes (11 fs-13 mJ). Les résultats d'une modélisation réalisée au CEA/SPAM, en bon accord avec les résultats expérimentaux, ont permis d'approfondir la compréhension des divers mécanismes mis en jeu. Afin de produire des impulsions encore plus courtes, il est nécessaire de travailler directement dans les chaînes laser, en amont du système de post-compression. Le rétrécissement spectral par le gain dans leTi:saphir des chaînes laser, limite en général les durées des impulsions à 30 fs. Ce phénomène, étudié lors de cette thèse, a été compensé grâce à une modulation de perte spectrale (filtre) dans le pré-amplificateur (cavité régénérative), localisée au maximum de la courbe de gain. Des impulsions de l’ordre de 20 fs ont été obtenues. Ces études ont été complétées par une modélisation de l'amplification des impulsions qui s'est avérée en très bon accord avec les mesures expérimentales. La possibilité de combiner ces procédés permettra, àcourt terme, la production d'impulsions laser sub-10 fs énergétiques (~10 mJ) pour générer des impulsions XUV attosecondes isolées
High energy ultrashort pulses are highly desirable for many applications. In thismanuscript, we described several methods for pulse duration reduction at high energy. A postcompressionsystem, using SPM-NER in a fused silica plate, has firstly provided 16 fs-5mJpulses, from 50 fs pulses. In a second part, we present a new efficient post compressiontechnique, achieved through ionization of gas in a capillary. With this technique, ultrashortand high energy pulses have been reached (11 fs-13 mJ). Results from modeling done atCEA/SPAM, in good agreement with the experimental ones, have been used to understanddeeply all the involved mechanisms. In order to get even shorter pulses, it is incontrovertibleto work on the laser chain, in front of the post-compression systems. In general, due tospectral gain narrowing in Ti:Saphir laser chain, the pulse duration is limited to 30 fs. Thiseffect, investigated in this thesis, has been compensated by modulating the spectral losses(filter) in the pre-amplifier (regenerative cavity), localized at the gain curve maximum. Pulseduration in the order of 20 fs has been obtained. This study has been completed with a pulseamplification model that shows very good agreement with the experimental measurements.The possibility to combine these processes should generate, in the short term, high energy (10mJ) sub-10 fs laser pulses to produce isolated XUV attosecond pulses

Abstract:
La nécessité de prouver l'existence de nouvelles particules comme les quarks et le boson de Higgs a entrainé le développement de deux nouveaux pans de la recherche : la physique des hautes énergies ou physique des particules, dédiée à prouver expérimentalement l'existence de ces particules puis à étudier leurs propriétés et la physique des accélérateurs, dédiée au développement de nouveaux instruments pour la physique des hautes énergies.Dans ce contexte, des collisionneurs linéaires électrons/positrons polarisés de forte luminosité dont l'énergie serait connue et accordable pourrait permettre d'étudier plus finement des particules se situant dans des énergies autour du TeV telles que le Boson de Higgs. C'est dans ce sens que le projet International Linear Collider (ILC) est conçu et c'est dans le cadre du développement de ce collisionneur linéaire de particules que cette thèse de doctorat se situe. Un des points critiques de l'ILC est la source de positrons polarisés. Sans entrer dans des explications sur la physique du processus de création de positrons polarisés, nous précisons simplement que ceux-ci sont créés lorsque des rayons gamma polarisés circulairement interagissent avec la matière. Le point critique est donc la source de rayons gamma polarisés circulairement. Une alternative pour cette source est la diffusion Compton inverse et c'est finalement dans le cadre de la recherche et du développement de systèmes lasers de fortes puissances moyennes asservis à des cavités Fabry-Perot pour la production de rayons gamma polarisés par diffusion Compton inverse que se situe cette thèse.Dans un premier temps, nous posons plus précisément le contexte de cette thèse, le principe de la diffusion Compton inverse ainsi que le choix d'une architecture optique basée sur un laser fibré et une cavité Fabry-Perot. Nous finissons sur une énumération des différentes applications possibles de la diffusion Compton inverse montrant que les travaux présentés pourraient bénéficier de transfert technologique vers d'autres domaines. Dans un second temps, nous présentons les différentes architectures d'amplification laser fibrée étudiées ainsi que les résultats obtenus. Dans un troisième temps, nous faisons un rappel du principe de fonctionnement d'une cavité Fabry-Perot et présentons celle utilisée pour notre expérience ainsi que ses spécificités. Dans un quatrième temps, nous abordons l'expérience de diffusion Compton inverse qui nous a permis de présenter pour la première fois à notre connaissance l'utilisation conjointe d'un laser à fibre optique et d'une cavité Fabry-Perot dans le cadre d'un accélérateur de particules pour générer des rayons gamma. Le dispositif expérimental ainsi que les résultats obtenus sont alors présentés. Finalement, nous résumons les résultats présentés dans ce manuscrit et proposons différentes possibilités d'évolution pour le système dans une conclusion générale.
