Extinction ratio conservation, wide dynamic range, and large operating wavelength window are important features for all-optical wavelength converters. Practical converters may probably be multistage devices and have to be precisely modeled. We present an experimental analysis and phenomenological modeling of single- and multistage wavelength converters using cross-gain modulation in polarization insensitive multiquantum-well optical amplifiers. One of the studied double-stage converters is able to produce a large extinction ratio improvement with a regeneration factor higher than 1.5 for any conversion in the 1.53-1.56-/spl mu/m window. The phenomenological model yields a very good agreement with the experimental results.read more

Performance analysis of wavelength converters based on cross-gain modulation in semiconductor-optical amplifiers
TL;DR: In this paper, an analytical theory describing all-optical wavelength converters based on cross-gain modulation (XGM) in semiconductoroptical amplifiers is derived, which consists of two parts: a large-signal analysis yielding the transmission function for the signal, and a small signal analysis in order to describe the transformation of the signal and probe intensity noise.

Cross-Gain Compression in Semiconductor Optical Amplifiers
TL;DR: In this article, a novel scheme that exploits cross-gain modulation (XGM) in semiconductor optical amplifiers (SOAs) without overall pattern effects is presented. But this technique uses two signals with reversed-intensity modulation and different wavelength to exploit propagation and gain-compression dynamics in gain-saturated SOAs at almost constant overall input power.
