An optical differential 8-PSK modulator using cascaded QPSK modulators

A new optical D8PSK modulator implementation is proposed. The proposed scheme removes the need for precise driving signal voltage control. Simulation results show the scheme enables modulation signal generation with more relaxed EO bandwidth requirements.
