Comparing the Performances of Optical DQPSK Signal Generated by Single Modulator With and Without Pulse Carver

Not Accessible

Abstract

Optical DQPSK signals are generated using one DD-MZM. Using a RZ carver, the ripple effect in the NRZ format can be effectively suppressed and 4 dB receiving sensitivity improvement can be achieved after 60km fiber transmission.
