Abstract

Wavelength converters play an important role in wavelength routed optical networks. Among these, an SOA-MZI based wavelength converter monolithically integrated with a tunable sampled-grating distributed Bragg reflector (SG-DBR) laser has been previously demonstrated [1] for amplitude shifted keying (ASK) signals. The integration of a tunable laser with the SOA-MZI enhances the reliability, the efficiency and the performance of the wavelength conversion process. Recently, the differential phase shift keying (DPSK) data format has received much attention owing to its higher immunity to optical nonlinearities in fiber transmission. In this work, we demonstrate 10-Gb/s DPSK wavelength conversion using a tunable SG-DBR laser-integrated SOA-MZI wavelength converter.
