Abstract :
We experimentally demonstrate and discuss a new technique for variable duty cycle return-to-zero (RZ) modulation, employing a phase modulator driven by a single electrical nonreturn-to-zero signal, and an optical delay interferometer. Unlike other methods for generating RZ, no synchronization between two electrical driving signals is needed.
