Abstract: Abstract This paper investigates a novel demultiplexing scheme for Nyquist optical time-division multiplexed (N-OTDM) signal using a single commercially-available IQ modulator. With only a free-run LO cascaded with a RF-driven IQ modulator at the receiver…

Abstract: Demultiplexing of high-speed Nyquist optical time-division multiplexed (N-OTDM) signal requires ultra-narrow local sampling pulse to avoid the severe inter-symbol-interference (ISI) between each tributary. Unfortunately, generation of such narrow sampling pulse is difficult or usually need…
