Optical Amplifier Options for Wideband Submarine Systems

The main wideband amplifier candidates for use in submarine systems are hybrid DRA/EDFA and C+L band EDFAs. We explore the relative merits of the two technologies and demonstrate through simulations that the hybrid approach is advantageous for most systems. Introduction Submarine systems have enjoyed the tremendous advances in coherent transmission brought about by high speed DSP technology ove...

Performance Evaluation of Wavelength Conversion Using a Wideband Semiconductor Optical Amplifier at 40 Gbit/s

In this paper, we will report and characterize the impact of the nonlinear polarization rotation on the behavior of a wavelength converter based on cross-gain modulation effect in a semiconductor optical amplifier (SOA) at 40 Gbit/s. Nevertheless, we investigate and evaluate its performance as function of the intrinsic and extrinsic SOA parameters, such as the bias current, the signal format, t...

Semiconductor-Optical-Amplifier Mach-Zehnder Interferometer Based Optical Networks

In this paper, an all-optical AND logic scheme which exploits the cross-phase modulation (XPM) effect in semiconductor-optical-amplifier-assisted Mach-Zehnder Interferometer (SOA-MZI), is proposed, performance analyzed and parameters optimized. The proposal is validated and the system performance under various parameters is examined through numerical simulations. With only moderate parameters, ...
