Paper Abstract

Gain-transparent semiconductor optical amplifier (GT-SOA) can be used as optical phase-modulators in Mach-zehnder interferometer configuration for 2R or 3R regeneration, wavelength conversion of differential phase modulated signals and all-optical format conversion from on-off keying (OOK) to binary phase shift keying (BPSK). Numerical simulation of the phase modulation effect of GT-SOA is performed using a wideband dynamic model and the performance is evaluated using the differential-phase-Q factor. Performance improvement by holding light injection is analyzed and non-return-to-zero (NRZ) and return-to-zero (RZ) modulation formats of the OOK signal are considered.
