Abstract

We propose an optoelectronic time-division demultiplexing scheme based on phase modulation and spectral filtering. The frequency of phase modulation is quarter the bit rate of the optical signal. Therefore, our scheme is applicable to 160-Gbit/s systems by using only a commercially available 40-GHz LiNbO3 phase modulator and optical filter. The power penalties are less than 2 dB for all tributaries, when a 160-Gbit/s signal is demultiplexed by our scheme.
