Abstract

A novel scheme to generate orthogonal modulation label based on differential phase-shift keying (DPSK) payload and duobinary RZ label has been proposed. The duobinary RZ label with tunable pulse-width and extinction ratio is generated by using a differential Mach-Zehnder modulator (DMZM). Our numerical simulation results have shown that both DPSK payload and duobinary RZ label have large receiver power margin.
