摘要

We demonstrate a simple method of generating time division multiplexed pulse trains with correlated and controlled phase, only using low-cost birefringent crystals and polarizers. As an illustration of this method, we achieve carrier-suppressed RZ (CS-RZ) pulse trains at 20GHz and 40GHz respectively by multiplexing 10GHz ultrashort pulse train. Furthermore, by numerical simulations, it is verified that the suitable phase-modulated pulse train generated by our method can be applied to high speed optical transmission system for suppressing intrachannel nonlinear effects.
