Paper Abstract

A complete analytical model of the polarization characteristics of a semiconductor laser amplifier in a loop mirror (SLALOM) is presented. Based on this model, various kinds of output for all-optical conversion of non-return-to-zero (NRZ) to pseudo-return-to-zero (PRZ) signals, based on a simple SLALOM scheme, are analyzed theoretically. Simulation results were in good agreement with experimental results on 20-Gbit/s all-optical NRZ-to-PRZ conversion. The results show that the theoretical model proposed in this paper is right, and proper polarization-state control is helpful for improving the output characteristics in all-optical pattern conversion.
