Demodulation of 320-Gbit/s Optical Quadrature Phase-shift Keying Signal with Digital Coherent Receiver having Time-division Demultiplexing Function

摘要

We demodulate a 320-Gbit/s optical quadrature phase-shift keying (QPSK) signal using a novel digital coherent receiver, which features a function of time-division demultiplexing with a local oscillator pulsed at the 10-GHz base-clock frequency.
