Abstract :
A novel cascaded Mach-Zehnder interferometer configuration is proposed for an adaptive delay DPSK demodulator. We demonstrate that the 2-cascaded MZI configuration can realize three delay settings substantially, and can suppress the penalty caused by bandwidth narrowing at cascaded ROADM filters.
