This paper presents a detailed theoretical and experimental study of the impact of amplified
spontaneous emission (ASE) on self-phase modulation in semiconductor optical amplifiers …

We study, theoretically and experimentally, interband four-wave mixing in semiconductor
optical amplifiers whose gain recovery is accelerated by amplified spontaneous emission …

We report remarkably fast and strongly wavelength-dependent gain recovery in a single
SOA without the aid of an offset filter. Full gain recovery times as short as 9 ps were …

A novel and comprehensive model for semiconductor optical amplifiers (SOAs) to be used in
high bit rate (10-160 Gb/s) optical communication systems is presented. Its uni-directional …

We study the relationship of the material transparency wavelength with a semiconductor
optical amplifier's (SOA's) bias current and length theoretically. The dependence of the gain …

Based on nine up-to-date types of semiconductor-optical-amplifier (SOA) samples, we
devised a power-consumption model of SOA-based all-optical gates as a tool to develop …

This paper presents detailed numerical and experimental study of SPM in semiconductor
optical amplifiers (SOAs) with ultrafast gain-recovery times. These SOAs have a range of …

We experimentally and theoretically demonstrate the semiconductor optical amplifier (SOA)
gain recovery-time (RT) dependence on the probe signal wavelength and power when …

By using the pre-signal light as the control light, we propose a method to suppress the
transient effect of erbium-doped fiber amplifiers for low-frequency pulse signals. The pattern …

Operating characteristics of terahertz optical asymmetric demultiplexer (TOAD), under gain
and transparent region assist light injection, are investigated in theory. We have analyzed …
