Abstract :
We present a novel differential phase shift keying receiver design under strong optical filtering. The receiver design is based on the different offset filtering performances of the output ports of the NRZ-DPSK Mach Zehnder Interferometer. The asymmetrical filtered receiver design can significantly increase performance by 2 dB in calculated “Q” for an OSNR of 15 dB.
