Improving transmission performance using a waveguide filter in all-optical wavelength converters

摘要

Wavelength converters based on cross-gain modulation in a semiconductor optical amplifier (SOA) are limited by pattern dependence and large chirp at high bit rates. We eliminated pattern dependence and realized 40 km SMF transmission of the converted signal from a SOA by using a waveguide narrow band filter at 10 Gbit/s.
