Abstract :
We present numerically and experimentally the combined impact of an asymmetric receiver design and a partial 42.7 Gb/s DPSK system. By implementing an optimized bit period delay at the MZI and Asymmetric filtering at the destructive port, system performance can be significantly improved by 1.8 dB for an OSNR of 20 dB.
