✦ Synopsis

The pulse con¨ersion characteristics of an interferometric wa¨elength con¨erter using XPM in SOA and the influence of the ASE on the con¨ersion process are analyzed in the time domain. The ¨ariations of the output extinction ratio without and with ASE are obtained for different SOA lengths and probe-power split ratios. From the extinction ratio ¨ariation for the input signal power le¨el, the optimized operating condition for a small ASE noise effect is discussed. The influence of the ASE on the extinction ratio of the con¨erted signal as a function of wa¨elength-con¨ersion bandwidth is also obtained.

## Abstract We propose an all‐optical switch based on cross‐polarization modulation in a semiconductor optical amplifier (SOA), operating at 2.5 Gbits/s with an NRZ pseudorandom data sequence. The effect consists of an induced modification of the birefringence and waveguide eigenmodes of an SOA pro
