Tunable DPSK Wavelength Converter Using an SOA-MZI Monolithically Integrated with a Sampled-Grating Distributed Bragg Reflector

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 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. In this work, we demonstrate 10-Gb/s DPSK wavelength conversion using a tunable SG-DBR laser-integrated SOA-MZI wavelength converter.
