640-Gb/s OTDM RZ-DQPSK signal enabling 2.4-bit/s/Hz spectral efficiency and its detection with an EAM-based receiver

Abstract

We demonstrate for the first time 640-Gb/s single-channel OTDM RZ-DQPSK signaling with record spectral efficiencies of 2.4 bit/s/Hz and up to 3.2 bit/s/Hz. The demonstrated data rate is the highest to date detected with an electro-absorption modulator (EAM) based receiver.
