Available in PDF, EPUB and Kindle. Book excerpt: Four Wave Mixing (FWM) in a semiconductor optical amplifier (SOA) is a third order nonlinear effect, which has various potential applications in high-speed optical communication systems. Continuous-wave (CW) FWM in a 2-section SOA has been experimentally studied. The carrier density modulation and nonlinear gain effects in the semiconductor optical amplifier contribute to the generation of the FWM. A theoretical model of CW FWM and frequency response of FWM using small signal analysis has been developed. Bandwidth of the FWM has been obtained for the first time. Pulsed FWM in the 2-section SOA has also been studied and analyzed. Optical time-division demultiplexing and wavelength conversion using the FWM in the SOA has been demonstrated for optical communication. A tunable Erbium doped fiber laser, which is preferred in the FWM experiments and is potentially an important source for high speed optical communication, has also been investigated. The tunability of the fiber laser is about 40 nm for both CW and mode-locking cases. Actively harmonic mode-locking which happens when the modulation frequency fm = n fc (fc is the fundamental cavity frequency) and rational harmonic mode-locking which happens when fm = (n + 1/p)fc (n, p are both integers) have been studied and analyzed. 22nd order of rational harmonic mode-locking was observed when f m 1 GHz, which is the highest order of rational harmonic mode-locking ever reported. 40 GHz pulse train with pulse width âˆ1⁄47 ps was achieved using rational harmonic mode-locking technique when f m 10 GHz. Stabilization of the mode-locked Er-doped fiber laser with a semiconductor optical amplifier in the cavity has also been studied. The semiconductor optical amplifier contributes in removing the supermode noise and stabilizing the optical pulses.

Available in PDF, EPUB and Kindle. Book excerpt: Optical amplifiers play a central role in all categories of fibre communications systems and networks. By compensating for the losses exerted by the transmission medium and the components through which the signals pass, they reduce the need for expensive and slow optical-electrical-optical conversion. The photonic gain media, which are normally based on glass- or semiconductor-based waveguides, can amplify many high speed wavelength division multiplexed channels simultaneously. Recent research has also concentrated on wavelength conversion, switching, demultiplexing in the time domain and other enhanced functions. Advances in Optical Amplifiers presents up to date results on amplifier performance, along with explanations of their relevance, from leading researchers in the field. Its chapters cover amplifiers based on rare earth doped fibres and waveguides, stimulated Raman scattering, nonlinear parametric processes and semiconductor media. Wavelength conversion and other enhanced signal processing functions are also considered in depth. This book is targeted at research, development and design engineers from teams in manufacturing industry, academia and telecommunications service operators.

This book was released on 2020-11-24 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Master's Thesis from the year 2019 in the subject Instructor Plans: Computing / Data Processing / IT / Telecommunication, , course: M.Tech, language: English, abstract: With the evolvement of high speed and long-distance data communication systems, conventional band erbium-doped fiber amplifiers (C-EDFAs) are getting more attention in recent times. Major advantage of the C-band EDFA is that it provides the user to realize a system with wide bandwidth of 40 nm. But, from the reported works, it is evident that for Gain enhancement in C-band using EDFA is reported with the use of multiple stages, multiple pumps, Gain flattening filters etc. However, these techniques suffered from high cost, complex techniques, and low performance. Here enhancement process was done through the narrowband Fiber Bragg Gratings (FBG) or fiber reflectors mirrors. In this work, a conventional band erbium doped fiber amplifier is proposed with high gain and less noise figure by incorporating the two fiber bragg gratings (FBGs) for amplified spontaneous noise reinjection. Maximum ASE is emerged at 1565 nm for the at -55 dBm carrier powers. Maximum gain is found out to be 48.16 dB with noise figure of 5.29 dBm. Fiber amplifiers are crucial and fast-growing field in the communication system. The study of this field show that the formulation procedures of lasers generation and amplifier amplification displays a problematical process due to the factors affecting and changing amplifier and laser significances in a dynamic way. Gain, noise figure, wavelength, power flatness and power output are directly affected by any element or parameter inside the amplifier configuration. The design parameters such as: erbium ions concentration, EDF length, isolators, wavelength division multiplexing (WDM) position, pump power position, circulators, pump directions, all of these elements and factors are affecting directly the amplifier output. EDFA is an amplifier that is best used because of its low loss and high gain. For communication, there are two windows 1530-1560nm(C-band) and 1560-1610nm (L-band).

Available in PDF, EPUB and Kindle. Book excerpt: The object of this school, held at Cargese, Corsica (France) from August 12th to 24th 1991, was the presentation of the field of guided wave nonlinear optics in a comprehensive, coherent, and heuristic fashion. It seems appropriate that this school began with an historical introduction by Professor Nicolaas Bloembergen of Harvard, the acknowledged "father" of nonlinear optics, in general, and concluded with a round table discussion headed by Dr. Eric Spitz, the Scientific Director of a multinational electronics company interested in developing industrial applications of guided wave nonlinear optics. The lectures covered both the theoretical framework of the field and applications to basic scientific research, optical communications and technical instrumentation. Specific topics developed included materials for guided wave nonlinear optics, nonlinear interactions using integrated optical guides, nonlinear surface waves, solitons, fiber nonlinear optics, ultra-fast coupler switching as well as the related topic of fiber and integrated optical lasers and amplifiers. Lectures have also been devoted to squeezed states, chaos and strange attractors. The subjects covered by the school underlines one of the major ways in which this field has evolved over the past thirty some odd years. The path from the original experiments with materials requiring mega-watt power lasers to the recent developments in guided wave configurations using milliwatt power diode lasers is marked by the conjunction of ever improving fundamental scientific comprehension and continuing technological developments.
