Abstract:

The development of all optical communications could benefit from the index guiding photonic crystal fibers. In communication the photonic crystal fibers could provide many new solutions. Conventional optical fibers have within the last decades revolutionized the communications industry and it is today a mature technology being pushed to its limit with respect to properties such as losses, single mode operation and dispersion. The spectra have been used by others to develop optical frequency standards. The process can potentially be used for frequency conversion in fiber optic network. In this system the dispersive properties can be controlled by the optical lattice making it possible to achieve phase-matched four wave mixing, like look the process taking place in the photonic crystal fibers. In this paper we will discuss the use of photonic crystal fibers in communications.

Abstract:

The aim of the study was to verify the usefulness of commercially available granulates of PMMA (poly (methyl methacrylate) and PS (polystyrene) for the production of polymer optical fibers by extrusion method. Samples were subjected to thermal processing in various conditions (different temperatures and exposure time). Thermal (TG/DTG) and spectroscopic (ATR/FT-IR) analyses were carried out to analyze changes in the samples. Based on FT-IR analysis of liquid monomers and granulates the conversion of double bonds was calculated, which gave us a picture of the degree of monomers conversion, crucial information from the technological point of view.

Abstract:

In current local area networks, multimode fibers (MMFs), mainly graded index (GI) MMFs, are the main types of fibers used for data communications. Because of their high bandwidth, they are considered the main method of transmission that allows to offer multiservice broadband services using optical multiplexing techniques. The MGDM (ModeGroup Division Multiplexing) is a Multiplexing technique, which aims to improve the performance of the multimode optical fiber by spatially multiplexing the data streams to be transmitted. In this work, we study optical MIMO (multi-input multi-output) transmission systems on an MMF optical fiber, specifically the adaptation of the architecture of MIMO transmission systems. In this context, we have studied the mode group multiplexing technique (MDGM), to evaluate the transmission capacity. In fact, the latter depends on the injection conditions and the state of the optical fiber.

Abstract:

This paper examines the wavelength assignment problem for single, dual, and multimessage multicasting over a star network with optical switching between fibers along the same wavelength. The specific problem we consider is given any star network, a predetermined number of fibers that connect its nodes, and a set of multicasts (or multidestination messages) to be delivered in one communication round, find a conflict free message transmission schedule that uses the least number of wavelengths per fiber. When the least number of wavelengths, λmin, exceeds the number available, λavl, one may transform the schedule into one with ⌈λmin/λavl⌉ communication phases or rounds over the same network, but restricted to λavl wavelengths per fiber.

Abstract:

The fiber optics technology is constantly being developed, and is becoming an essential component of contemporary communications, medicine and industry. Fibers, their connections and system components play a major role in optical signal transmission, telecommunications, power transmission, and sensing processes using fiber technology. The two main light propagation characteristics of an optical fiber are attenuation and dispersion. The possibility of controling these parameters is of utmost importance for obtaining the requested transmission quality. This paper reports on an investigation to determine the influence of gamma radiation of 60Co on the variation of optical fiber propagation parameters, such as polarization mode dispersion. In addition, it also considers chosen topics in the field of fiber optics technology.

Abstract:

Researchers are within a factor of 2 or so from realizing the maximum practical transmission capacity of conventional single-mode fibre transmission technology. It is therefore timely to consider new technological approaches offering the potential for more cost-effective scaling of network capacity than simply installing more and more conventional single-mode systems in parallel. In this paper, I review physical layer options that can be considered to address this requirement including the potential for reduction in both fibre loss and nonlinearity for single-mode fibres, the development of ultra-broadband fibre amplifiers and finally the use of space division multiplexing.

Abstract:

Optical fibers, in particular, glass fibers, are mostly used in the field of optical communication, however in recent years new optical sensors based on the optical fibers have been reported in literature and produced commercially. Extrinsic and intrinsic character of the fibers have been implemented in development of such sensing devices. Glass Optical Fibers (GOF) because of low attenuation are more suitable for the optical communication purposes while Plastic Optical Fibers are advantageous for the linking purpose and some sensing operations. Considering this point different (POF) optical fiber sensors have been developed by author to show potential applications of POFs in sensor technology. New simple devices at the minimum cost are introduced in this study. Results for light reflection sensing, light leakage sensing, level sensing, and distance gauging are obtained. Presented systems are mostly in bulk form, however, these devices with good results show that in principle, these ideas can be implemented in design of small scale devices. It seems to be a great potential to apply these ideas in order to develop new devices suitable for compact and integrated applications. In this article some examples are given in which the reported results verify the concept and applicability of such devices for future sensing technology.

Abstract:

To overcome the problem that the artificial scheduling can not deal with optical fiber switching in time when optical fiber is broken or damage in power system, we designed an optical fiber line auto switch protection system. The system used six 4x4 optical switches to compose an optical switch array that eight working fibers can share four alternate fibers. Comparing with other system, the new system more effectively utilizes alternate fibers, and is more suitable for practical power system. It used single chip microcomputer as control chip of optical switch, when the received optical power is lower than predefined threshold, the control chip will control the optical switch to alternate fiber line in time to ensure the real time and reliability of optical fiber communication. In the same time, the new system can communicate with host computer to alarm, display fault optical fiber line and remote control, and be controlled by button to realize the manual switch of optical fiber line.

Abstract:

Nonlinear effects in optical fibers impose different limitations on the communications link, and an understanding of such effects is almost a prerequisite for actual lightwave-system designers. On the other hand, they offer a variety of possibilities for all-optical signal processing, amplification and regeneration. The nonlinear effects are enhanced dramatically, and new phenomena are observed in the so-called photonic crystal fibers. In this paper, we review the effects — both detrimental and potentially beneficial — of optical nonlinearities in conventional and in photonic crystal fibers.

Abstract:

Due to their flexible structure and excellent optical characteristics hollow-core photonic crystal fibers (HC-PCFs) are used in many fields, such as active optical devices, communications, and optical fiber sensing. In this paper, to analyze the characteristics of HC-PCFs, we carried out finite element analysis and analyzed the design for the band gap cladding structure of HC-PCFs. First, the characteristics of HC19-1550 and HC-1550-02 in the C-band were simulated. Subsequently, the structural optimization of the seven-cell HC-1550-02 and variations in characteristics of the optimized HC-1550-02 in the wavelength range 1250–1850 nm were investigated. The simulation results revealed that the optimal number of cladding layers is eight, the optimal core radius is 1.8 times the spacing of adjacent air holes, and the optimal-relative thickness of the core quartz-ring is 2.0. In addition, the low confinement loss bandwidth of the optimized structure is 225 nm. Under the transmission bandwidth of the optimized structure, the core optical power is above 98%, the confinement loss is below 9.0 × 10−3 dB/m, the variation range of the effective mode field area does not exceed 10 μm2, and the relative sensitivity is above 0.9570. The designed sensor exhibits an ultra-high relative sensitivity and almost zero confinement loss, making it highly suitable for high-sensitivity gas or liquid sensing.

Abstract:

The orbital angular momentum (OAM) of light provides a new degree of freedom for carrying information. The stable propagation and generation of OAM modes are necessary for the fields of OAM-based optical communications and microscopies. In this review, we focus on discussing the novel fibers that are suitable for stable OAM mode transmission and conversion. The fundamental theory of fiber modes is introduced first. Then, recent progress on a multitude of fiber designs that can stably guide or generate OAM modes is reviewed. Currently, the mode crosstalk is regarded as the main issue that damages OAM mode stability. Therefore, the coupled-mode theory and coupled-power power theory are introduced to analyze OAM modes crosstalk. Finally, the challenges and prospects of the applications of OAM fibers are discussed.

Abstract:

The fourth generation of optical fibers is wavelength division multiplexing (DWDM), where several wavelengths propagate in a single optical fiber. This technique strongly supports broadband communication that is currently being developed. An optical amplifier (EDFA) is required for transmitted information to be received at the appropriate distance limits. The problem, where EDFA should be located and how to overcome the chromatic dispersion of signals occurs, especially on remote communications using SMF 28. The power budget analysis starts from the calculation of the distance between the amplifier and the strengthening of EDFA using the solution wave equation, where the large dispersion of chromatic fiber and the desired range becomes the determinant of the optical amplifier. Case study for 200 km of communication distance need three amplifiers with a space of about 80km. When a 1 GHz bandwidth is converted to 10 GHz, OSNR on each amplifier will decrease by 10 dB.

Abstract:

The influence of nuclear radiation and particles has been the object of investigation for a long time. For new materials and systems the research should be continued. Human activities in various environments, including space, call for more detailed research. The role of fibers in contemporary communications, medicine, and industry increases. Fibers, their connections and fused optics components have one type of tasks - the transmission of information and power. The other type of tasks is reserved for fiber lasers: quantum generators and amplifiers. The third type of tasks is for fiber sensors, including high energy nuclear physics. In this paper we present some chosen topics in the mentioned areas as well as our experiments with nuclear radiation and laser beams to fiber and bulk materials of various nature (glass, polymer, metallic, etc.).

Abstract:

The main goal in this paper is to design single-mode optical fibers for DWDM networks, which are used today in rapid communications. These networks require low dispersion in a wide range of wavelengths. So, in this paper, multi-layer optical fibers with low dispersion value and flat dispersion slope in wavelength range of 1.5-1.6µm) are designed, using optimization algorithms.

Abstract. This paper presents the research on optimization of the splicing process in the electric arc of telecommunication optical fibers and erbium doped EDF fibers. The results of the calculations of diffusion coefficients GeO2 in telecommunication optical fibers and diffusion coefficients Er and Al2O3 (together) in the fiber EDF are presented. Diffusion coefficients were determined for the fusion temperature in the electric arc ≈2000°C, on the basis of changes, along the splice, of spliced thermoluminescence intensity profiles of the fibers. On the basis of knowledge of diffusion coefficients simulation calculation of loss joints of MC SMF fiber (Matched Cladding Single Mode Fiber - SiO2: GeO2) and NZDS SMF (Non Zero Dispersion Shifted - Single Mode Fiber - SiO2: GeO2) with EDF (Erbium Doped Fiber - SiO2: Al2O3, Er) was performed and presented as a function of diffusion time. Experimental studies of optimization of thermal connected MC SMF and NZDS SMF with EDF were presented and compared with theoretical results. This paper presents the results of microscopic observations of defects and diffusion, and X-ray microanalysis in the spliced areas of single-mode telecommunication optical fibers: MC SMF, NZDS-SMF and erbium doped active single mode optical fibers. Studies were performed with the use of the scanning electron microscope JSM5800LV and JSM6610A microscope equipped with EDS X-ray spectrometer. Results showing the influence of heating time on the diffusion of core dopants and the formation of deformations in the splice areas were presented.

Abstract:

In an optical communication system it is necessary to place the solitons close to one another to increase the information carrying capacity of the fiber. The theory of soliton–soliton interaction in a fiber optic communication system, through a single channel, is studied in this paper. In presence of the perturbation terms, the two soliton interaction of the Nonlinear Schrödinger's Equation is investigated. It is analytically proved and numerically supported that the perturbation terms lead to the suppression of the interaction of solitons through an optical fiber.

Abstract:

We study the blocking probability and performance of single-fiber and multifiber optical networks with wavelength division multiplexing (WDM). We extend the well-known analytical blocking probability model by Barry and Humblet to the general model, which is proposed for both single-fiber and multifiber network paths with any kind of wavelength conversion (no, limited, or full wavelength conversion) and for uniform and nonuniform link loads. We investigate the effect of the link load, wavelength conversion degree, and the number of wavelengths, fibers, and hops on blocking probability. We also extend the definition of the gain of wavelength conversion by Barry and Humblet to the gain of performance, which is fully general. Thanks to this definition and implementation of our model, we compare different WDM node architectures and present interesting results.

Abstract:

Light has found applications in data transmission, such as optical fibers and waveguides and in optoelectronics. It consists of a series of electromagnetic waves, with particle behavior. Photonics involves the proper use of light as a tool for the benefit of humans. It is derived from the root word “photon”, which connotes the tiniest entity of light analogous to an electron in electricity. Photonics have a broad range of scientific and technological applications that are practically limitless and include medical diagnostics, organic synthesis, communications, as well as fusion energy. This will enhance the quality of life in many areas such as communications and information technology, advanced manufacturing, defense, health, medicine, and energy. The signal transmission methods used in wireless photonic systems are digital baseband and RoF (Radio-over-Fiber) optical communication. Microwave photonics is considered to be one of the emerging research fields. The mid infrared (mid-IR) spectroscopy offers a principal means for biological structure analysis as well as nonintrusive measurements. There is a lower loss in the propagations involving waveguides. Waveguides have simple structures and are cost-efficient in comparison with optical fibers. These are important components due to their compactness, low profile, and many advantages over conventional metallic waveguides. Among the waveguides, optofluidic waveguides have been found to provide a very powerful foundation for building optofluidic sensors. These can be used to fabricate the biosensors based on fluorescence. In an optical fiber, the evanescent field excitation is employed to sense the environmental refractive index changes. Optical fibers as waveguides can be used as sensors to measure strain, temperature, pressure, displacements, vibrations, and other quantities by modifying a fiber. For some application areas, however, fiber-optic sensors are increasingly recognized as a technology with very interesting possibilities. In this review, we present the most common and recent applications of the optical fiber-based sensors. These kinds of sensors can be fabricated by a modification of the waveguide structures to enhance the evanescent field; therefore, direct interactions of the measurand with electromagnetic waves can be performed. In this research, the most recent applications of photonics components are studied and discussed.

Abstract:

For years, scientists have been looking for different techniques to make glasses perfect: fully amorphous and ideally homogeneous. Meanwhile, recent advances in the development of particle-containing glasses (PCG), defined in this paper as glass-ceramics, glasses doped with metallic nanoparticles, and phase-separated glasses show that these “imperfect” glasses can result in better optical materials if particles of desired chemistry, size, and shape are present in the glass. It has been shown that PCGs can be used for the fabrication of nanostructured fibers—a novel class of media for fiber optics. These unique optical fibers are able to outperform their traditional glass counterparts in terms of available emission spectral range, quantum efficiency, non-linear properties, fabricated sensors sensitivity, and other parameters. Being rather special, nanostructured fibers require new, unconventional solutions on the materials used, fabrication, and characterization techniques, limiting the use of these novel materials. This work overviews practical aspects and progress in the fabrication and characterization methods of the particle-containing glasses with particular attention to nanostructured fibers made of these materials. A review of the recent achievements shows that current technologies allow producing high-optical quality PCG-fibers of different types, and the unique optical properties of these nanostructured fibers make them prospective for applications in lasers, optical communications, medicine, lighting, and other areas of science and industry.
