ABSTRACT:
The optical signal produced by a semiconductor-optical-amplifier based wavelength converter is passed through an optical discriminator. The resulting signal has improved extinction ratio for return-to-zero data and improved high-frequency response for both non-return-to-zero and return-to-zero data.
