This book was released on 2018 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main purpose of the study is to investigate the nonlinear effects four wave mixing (FWM) and cross gain modulation (XGM) in wavelength division multiplexing (WDM) system. In addition, the study contributed the methods which are used to examine the impact of these effects on a transmission system consisting erbium doped fiber amplifiers (EDFAs) and a multiplex of coherent channels ; generally, this work is divided into two major parts. First, the investigation of FWM and XGM effects in transmission system. It also includes several modulation formats of DWDM system for return to zero (RZ), non return to zero (NRZ), and duobinary modulation format (DRZ). The second major objective is to reduce both of the nonlinear effects XGM and FWM in DWDM optical transmission system. The simulations are executed to optimize the device performance for the WDM system considering the limitation imposed by the nonlinear effects in multiwavelength systems with in line optical amplifiers and repeaters. Unequal channel spacing in multichannel transmitter and duobinary modulation technique is proposed in this researchto overcome this limitation.

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.

Book excerpt: Optical communications networks are becoming increasingly important as there is demand for high capacity links. Dense wavelength division multiplexing (DWDM) is widely deployed at the core networks to accommodate high capacity transport systems. Optical components such as optical amplifiers, tunable filters, transceivers, termination devices and add-drop multiplexers are becoming more reliable and affordable. Access and metropolitan area networks are increasingly built with optical technologies to overcome the electronic bottleneck at network edges. New components and subsystems for very high speed optical networks offer new design options.The proceedings of the First International Conference on Optical Communications and Networks present high quality recent research results in the areas of optical communications, network components, architectures, protocols, planning, design, management and operation.

Book excerpt: In the last decade, China has experienced one of the fastest economic growth in the world. Leading this enormous growth is the development of telecommunications that has a growth rate far exceeding that of its GNP. With such fast growth, China will have the largest telecommunication network with 420 million lines by 2010. The backbone of the national telecom network in China is primarily optical fiber cables today.This book contains a selection of reports reviewing the progress of the research and development in optoelectronics and optical fiber communications in China. The first four papers focus on the current development in optical fiber communications with particular interest in studies of soliton transmission and optical WDM transmission experiments. The next four papers describe the research results on quantum well lasers, bi-stable lasers, electro-absorption modulators and SEED, and photonic integrated devices. Fiber ring lasers using EDFA and the ASE noise in the PIN receiver due to EDFA are discussed in the next two papers, respectively. The last two papers describe the research activities and results of the development of the GaAs ICs for high speed lighwave systems, and their characterization using optical sampling techniques.

Book excerpt: Our research is focused on theoretical investigations of advanced optical fiber communication systems and can be grouped into three broad areas: WDM networks, coherent analog links, and optical fiber nonlinearities. In the area of WDM networks, we proposed and investigated a novel WDM network architecture (STARNET), a novel combined phase/amplitude modulation format, and a high-speed optics-to-computer interface for STARNET. In the area of coherent analog links, we investigated angle and amplitude modulated systems for linewidth-insensitive analog applications and direct-frequency-modulated subcarrier-multiplexed systems. In the area of fiber nonlinearities, we investigated four-wave mixing, thermally induced parasitic phase modulation, and a new type of soliton.
