Abstract
A configuration of transmitter for superimposing DPSK signals on dark RZ signals with tunable duty cycle was proposed. The transmitter comprises two optical phase modulators and a delayed line Mach-Zehnder interferometer. The simulation results show that the spectral efficiency is doubled by using this scheme.
