Abstract:
In order to meet the needs of phase generated carrier (PGC) demodulation technology for interferometric fiber optic hydrophones, we proposed an optical microfiber all-optical phase modulator (OMAOPM) based on the photo-induced thermal phase shift effect, which can be used as a phase carrier generation component, so as to make the modulation efficiency and working bandwidth of this type of modulator satisfy the requirements of underwater acoustic signal demodulation applications. We analyzed the modulation principle of this modulator and optimized the structural parameters of the optical microfiber (OM) when the waist length and waist diameter of OM are 15 mm and 1.4 μm, respectively. The modulation amplitude of the modulator can reach 1 rad, which can meet the requirements of sensing applications. On this basis, the fiber optical hydrophone PGC-Atan demodulation system was constructed, and the simulated underwater acoustic signal test demodulation research was carried out. Experimental results showed that the system can demodulate underwater acoustic signals below 1 kHz.

Abstract:
Parametric modulation is an effective tool to measure the trap frequency and investigate the atom dynamics in an optical dipole trap or lattices. Herein, we report on experimental research of parametric resonances in an optical dipole trap. By modulating the trapping potential, we have measured the atomic loss dependence on the frequency of the parametric modulations. The resonance loss spectra and the evolution of atom populations at the resonant frequency have been demonstrated and compared under three modulation waveforms (sine, triangle and square waves). A phenomenological theoretical simulation has been performed and shown good accordance with the observed resonance loss spectra and the evolution of atom populations. The theoretical analysis can be easily extended to a complex waveform modulation and reproduce enough of the experiments.

Abstract:
This paper presents the analytical research and characterization of optical Binary Phase Shift Keying (BPSK) for single-tone sinusoidal and digital signals. The mathematical analysis and simulation for optimal modulation depth are proposed in this paper for maximum efficiency of the output modulated signal. The modulation depth is analysed with suitable Radio Frequency (RF) drive voltage for message signal and the effect of modulation depth on carrier suppression and higher order harmonics over fundamental tone is analysed theoretically and with simulation. To achieve phase modulation in this work, an external modulation technique via the Mach-Zehnder Modulator (MZM) is used, and an optical source using a narrow line width Distributed Feed Back (DFB) laser is used to minimise phase noise. The simulation and characterization results strongly support the mathematical analysis of the proposed criteria for suitable RF drive over half wave voltage for optimal detection and maximum message signal efficiency.

Abstract:
Optoelectronic devices which play important roles in high-speed optical fiber networks can offer effective measurement methods for optoelectronic devices including optical modulators and photodetectors. Precise optical signal modulation is required for measurement applications. This paper focuses on high-speed and precise optical modulation devices and their application to device measurement. Optical modulators using electro-optic effect offers precise control of lightwaves for wideband signals. As examples, this paper describes frequency response measurement of photodetectors using high-precision amplitude modulation and wavelength domain measurement of optical filters using fast optical frequency sweep. Precise and high-speed modulation can be achieved by active trimming which compensates device structure imbalance due to fabrication error, where preciseness can be described by on-off extinction ratio. A Mach-Zehnder modulator with sub Mach-Zehnder interferometors can offer high extinction-ratio optical intensity modulation, which can be used for precise optoelectronic frequency response measurement. Precise modulation would be also useful for multi-level modulation schemes. To investigate impact of finite extinction ratio on optical modulation, duobinary modulation with small signal operation was demonstrated. For optical frequency domain analysis, single sideband modulation, which shifts optical frequency, can be used for generation of stimulus signals. Rapid measurement of optical filters was performed by using an optical sweeper consisting of an integrated Mach-Zehnder modulator for optical frequency control and an arbitrary waveform generator for generation of a source frequency chirp signal.

Abstract:
We present the design of a plasmonic modulator based on hybrid orthogonal silver junctions using vanadium dioxide as the modulating material on a silicon-on-insulator. The modulator has an ultra-compact footprint of 1.8 μm × 1 μm with a 100 nm × 100 nm modulating section based on the hybrid orthogonal geometry. The modulator takes advantage of the large change in the refractive index of vanadium dioxide during its phase transition to achieve a high modulation depth of 46.89 dB/μm. The simulated device has potential applications in the development of next generation high frequency photonic modulators for optical communications which require nanometer scale footprints, large modulation depth and small insertion losses.

Abstract:
We demonstrate a system scheme of generating and transmitting base-band and radio frequency signal based on optical double-sidebands scheme to generate optical millimeter-wave signal via optical phase modulation (OPM) and FBG. The system architecture with the source of laser at central station, the data re-modulation on downlink optical carrier gained from one base station is a good method to reduce the cost of uplink transmitter, for it does not needs the source of laser and wavelength administration at the base station. The optical phase modulator is inexpensive and mature. The downlink communicated bandwidth can be doubled to realize Ultra Width Band & Ultra High Frequency (UHF) communication via phase modulation and FBG at the base station. And the other signal which is reflected by FBG can be reused as uplink via amplitude modulation availably. The simulation results show that the bi-directional 2.5Gbit/s data and UHF microwave with 24GHz is successfully transmitted over 50km distance of a single-mode optical fiber with a optical dispersion of 20ps/(nm·km), an optical attenuation of 0.25dB/km and a light source power of 3dBm.

Abstract:
Magneto-Optical modulation technology has become key component in many optical information systems. However, due to the abstract theoretical knowledge, many textbooks do not introduce the properties of circular anisotropy, so it is difficult for most students to understand the polarization properties of light accurately and in depth. In this paper, the processes of Magneto-Optical modulation are Three-Dimensionally dynamically simulated by using MATLAB software first. These simulations make the complex and abstract light propagation processes become visual, which are effective aids for optics’ teaching. These simulations can enhance the understanding of the concept and the interactions with media of polarized lights and the principles of Magneto-Optical modulation. Second, a magnetic rotation glass is used to produce Magneto-Optical modulator, and finally the optical communication simulation experiment is realized and the effect is good. Experimental results show that the magneto-optical modulator has advantages like low power requirements, low modulation voltage, simple device, flexible, long life-time and small affect to the external temperature etc.

Abstract:
In this research an approach to all optical delta sigma modulator (ADSM) has been elaborated. Two important components of ADSM; "leaky integrator" and "inverted bi-stable quantizer" were modeled, on the basis of cross gain modulation of the Semiconductor Optical Amplifier (SOA). The simulations (via VPI photonics) were all in micrometer scale (suitable for chip fabrication). By simulating each element of ADSM the whole circuit was simulated and results have been showed and analyzed. By investigating the ADSM, the limiting factor for reaching higher frequencies (THz) was recognized to be the quantization device. Thus a new optical switch was introduced, for the first time so called "proteresis." By applying proteretic bi-stable device in the delta sigma modulator, the resonance frequency was improved minimum two fold from 295MHz to 575MHz without making any change in hysteretic bi-stable switch. The broad impact of this research is on the digital technologies that can be utilized in high-speed signal processing. The prime examples are the RF technologies used in military and civilian applications. Furthermore introduction of proteresis opens a new research gate for compensating delay in almost every system.

Abstract:
The use of optical feedback for improving response linearity of electrooptic light modulators has been investigated. The modulator is configured as a straight channel waveguide flanked by electrodes in a lithium niobate (LiNbO3) substrate. Light is coupled into the waveguide in both TE and TM polarizations, and a voltage applied across electrodes causes a relative phase shift between two polarization components. An output analyzer converts the phase modulation to intensity modulation. Optical feedback of light in both polarization modes results from reflection of light at the polished edges of the substrate. Channel waveguides supporting a single guided mode for TE and TM polarizations were fabricated in x-cut LiNbO3 substrates using titanium-indiffusion technique. The waveguides and modulators were characterized at a wavelength of 1.55 ??m using a distributed feedback laser. The modulators were driven with a sinusoidal voltage waveform. To minimize harmonics of the modulating frequency in the intensity output, the magnitude of the optical feedback and the substrate temperature were adjusted. The feedback level was altered by applying refractive index-matching liquid to one or both ends of the waveguide at the edges of the crystal. It was found that a high degree of response linearity in the presence of feedback was achievable at certain substrate temperatures. The spurious-free dynamic range (SFDR) relative to the noise floor was measured at different feedback levels and substrate temperatures in an effort to maximize the modulator response linearity. An SFDR of 68.04 dB, limited by third-order nonlinearity, was achieved by applying index-matching fluid to the input end of the substrate. This compares with an SFDR of 64.84 dB limited by second-order nonlinearity when index-matching fluid was applied at both ends of the substrate. By changing the temperature of the same substrate to adjust the phase shifts experienced by TE and TM polarizations, the SFDR with index-matching fluid at the input end increased to 71.83 dB, limited by third-order nonlinearity. In tests at constant modulation depth, an improvement of as much as 9.6 dB in SFDR vs. the theoretical value for an interferometric modulator without feedback was achieved.

Abstract:
In this thesis three different microwave filter architectures based on optical phase modulation are proposed and demonstrated. The first photonic microwave filter consists of an electro-optic phase modulator (EOPM), a length of high birefringence (Hi-Bi) fiber, a 25-km single-mode fiber and a narrow linewidth laser source. In the second and the third photonic microwave filters, we focus on the technique to obtain bipolar coefficients based on phase modulation to intensity modulation (PM-IM) conversion. In the second filter, chirped fiber Bragg gratings (CFBGs) are used as PM-IM conversion devices. In the third filter, the negative coefficients are obtained by locating the optical carriers at the opposite slopes of the transfer function of an optical filter, to convert the phase-modulated signals to intensity-modulated signals, with phase inversion of the RF modulating signals. Based on this scheme, a two-tap microwave bandpass filter with one negative coefficient is demonstrated. (Abstract shortened by UMI.)

Abstract:
La demande toujours croissante pour la capacité du réseau conduit au développement de systèmes de communication optique pour couvrir les normes Terabit Ethernet récemment proposées. Les applications de courte distance nécessitent une solution peu coûteuse et peu complexe avec détection directe. Cependant, le coût de la détection cohérente diminue chaque jour et en fait un bon candidat pour les applications à courte distance futures afin d'accroître l'efficacité spectrale et d'utiliser des formats de modulation avancés. Dans cette thèse, nous étudions des solutions pour les applications court-courrier actuelles et futures. Dans la première partie, nous nous concentrons sur des solutions pour les applications de courte distance. Le premier chapitre est la première démonstration de la transmission multi-tonalité discrète (DMT) à plus de 100 Gb/s en utilisant une photonique au silicium en bande O (SiP). Nous comparons expérimentalement le DMT avec la modulation d'amplitude d'impulsion (PAM) sur la bande O. Notre expérience montre qu'en augmentant la longueur des fibres de plus de 10 km, la PAM surpasse le DMT. Pour la bande C, nous utilisons un multi-ton discret à bande latérale unique (SSB-DMT) pour éviter l'effet d'évanouissement de la puissance induit par la dispersion chromatique. Nous étudions l'effet du bruit de phase, de la dispersion chromatique et de la sensibilité du récepteur pour optimiser le signal du DMT et extraire des équations théoriques pour calculer le taux d'erreur binaire (BER) du SSB-DMT. Ensuite, nous comparons la PAM sur bande O avec le SSB-DMT sur bande C et quantifions l'impact des limitations imposées par le matériel sur les deux formats de modulation. Notre étude fournit un outil analytique pour les applications de courte distance afin de sélectionner le format et le matériel de modulation appropriés en fonction de la portée requise, du débit binaire, etc. Dans la deuxième partie, le ciblage des futurs systèmes de détection cohérents justifié l'utilisation d'un format de modulation complexe avec détection cohérente. Nous utilisons un format de modulation avancé dans lequel nous avons combiné la propagation de transformée de Fourier discrète avec le DMT pour augmenter l'efficacité spectrale. Le format de modulation hybride a un rapport de puissance crête à moyenne inférieur (vis-à-vis du DMT) et une efficacité spectrale plus élevée (vis-à-vis de la QAM _a porteuse unique). Dans la première étape, nous comparons expérimentalement les performances des modulations hybrides, DMT standard et monoporteuse en utilisant un modulateur SiP IQ. Ensuite, nous développons une stratégie de contrôle pour le format de modulation hybride en échangeant la non-linéarité de la fonction de transfert du modulateur et le rapport signal / bruit optique. Le format de modulation hybride est ensuite optimisé pour avoir un débit maximum. En utilisant une simulation de Monte Carlo, nous comparons le format de modulation hybride optimisé avec le DMT standard pour différents débits binaires. Enfin, nous avons une comparaison de complexité entre hybride et DMT pour différentes longueurs de fibre.
Ever increasing demand for network capacity is driving the development of optical communication systems to cover recently proposed Terabit Ethernet standards. Short haul applications need low cost and low complexity solutions with direct detection, as the cost of coherent detection comes down, it will become a good candidate for future short-haul applications to increase spectral efficiency and exploit advanced modulation formats. In this thesis, we investigate solutions for both current and future short-haul systems. In the first part, we focus on solutions for short haul applications. The first chapter is the first time demonstration of more than 100 Gb/s discrete multi-tone (DMT) transmission using an O-band silicon photonics (SiP). We experimentally compare DMT with pulse amplitude modulation (PAM) on O-band. Our experiment shows that by increasing fiber length more than 10 km, PAM outperforms DMT. For C-band, we use single sideband discrete multi-tone (SSB-DMT) to avoid chromatic dispersion-induced power fading e_ect. We study the effect of phase noise, chromatic dispersion, and receiver sensitivity to optimize DMT signal and extract theoretical equations to calculate bit error rate (BER) of SSB-DMT. Next, we analytically compare PAM on O-band with SSB-DMT on C-band and quantify the impact of hardware-imposed limitations on both modulation formats. Our study provides an analytical tool for short haul applications to select appropriate modulation format and hardware based on required reach, bit rate, etc. In the second part we examine complex modulation formats that will be enabled in the future by low cost, integrated components for coherent detection.. We use an advanced modulation format in which we combined discrete Fourier transform spread with DMT to increase spectral efficiency. Hybrid modulation format has a lower peak to average power ratio (vis-a-vis DMT) and higher spectral efficiency (vis-a-vis single carrier QAM). In the first step, we experimentally compare the performance of the hybrid, standard DMT, and single carrier modulations using a SiP IQ modulator. Next, we develop a driving strategy for hybrid modulation format by trading off the modulator transfer function non-linearity and optical signal to noise ratio. Then hybrid modulation format is optimized to have maximum throughput. Using Monte Carlo simulation we compare optimized hybrid modulation format with standard DMT for different bit rates. Finally, we have a complexity comparison between hybrid and DMT for different fiber lengths to motivate same investigation for long-haul applications where, we should consider fiber non-linearity, attenuation, a polarization multiplexing.

Abstract:
The high-throughput spatial light modulator (SLM) is a key component in an expanding range of optical signal processing applications and VLSI interconnect scenarios. With the continuing trend towards overall system integration, a number of approaches have been pursued in recent years, with the common aim of developing a silicon-compatible modulator system, preferably addressed via a fully integrated silicon back-plane with a 1:1 mapping between drive circuits and modulation elements. Potentially viable technologies investigated hitherto include liquid crystals [1,2,3], magneto optic materials.[4] and micromechanical devices fabricated in silicon itself [5], all of which exhibit relatively limited modulation rates.

Full text
Abstract:
Many optical communication systems, such as those based on free-space propagation, require significantly higher diffraction-limited transmitter power than is available from single-stripe laser diodes. An attractive solution is to use a high-power coupled stripe laser-diode array or broad stripe laser that is externally injection locked to achieve a diffraction-limited far-field emission.1 To encode the transmitted information, we could use direct array current modulation, but this requires large drive currents and is limited by relatively low modulation bandwidth of the array. One alternative is to frequency modulate the master laser for FSK transmission.2 Recent advances in optical damage-resistant waveguides3 permit the use of another approach, described here and shown in Fig. 1, where the information is first encoded as phase modulation on the master laser signal by using a LiTaO3 proton-exchanged waveguide phase modulator. Modulated output is then used to injection lock a coupled stripe array. When the phase-modulation spectral sidebands in the injected signal are within the locking bandwidth, the phase-modulated signal is amplified and transmitted by the injection-locked laser without suppression of the modulation index.4

Abstract:
Mode Vector Modulation (MVM) is a spatial, multidimensional modulation format for short-haul, optical interconnects. We evaluate the back-to-back performance of optically-preamplified MVM direct-detection receivers and prove that MVM is superior to conventional binary modulations.

Full text
Abstract:
Progress has been made on an integrated acoustooptic modulator needed for a proposed optical communication network. The system, which is described elsewhere,1 can employ a standing wave surface acoustic wave (SWSAW) to generate microwave subcarriers needed to multiplex analog and/or digital signals. Previous experiments demonstrated intensity modulation of a guided optical beam at a frequency of 70 MHz by a SWSAW which diffracted light in the Raman-Nath regime.1,2 Intensity modulation of an optical beam at 600 MHz has been observed recently using a Bragg version of this modulator. Superimposing NTSC VHF TV signals on the bias current of the laser diode resulted in mixing between the TV signals and the 600-MHz acoustooptic modulation. Hence, the VHF TV signals were optically upconverted into the UHF range by the acoustooptic modulator. A photodiode was used to convert the UHF signals back into an electrical form. The carrier-to-noise ratio (CNR) was at least 30 dB for the picture carriers of the upconverted TV signals. The observed picture quality was good.

Full text
Abstract:
High-speed and low-chirp external optical intensity modulators are important for future high-bit rate transmission systems, because in direct modulation of a laser diode the transmission bandwidth is limited by the large chirp during relaxation oscillation. A GaInAsP/InP optical intensity modulator [1], [2] is one of the candidates for such an external modulator. However it has been recently pointed out that some chirp is caused in such an electroabsorption modulator by the accompanied phase modulation [3]. Until now the dynamic spectral broadening factor αE which characterizes chirp was obtained only from a ratio of average power in optical sidebands to carrier power under sinusoidal modulation [2]. But it is necessary to evaluate, the chirp under large signal pulse modulation in order to apply to the system. Here we report high-speed and low-chirp characteristics in a newly developed GaInAsP/InP optical intensity modulator.
