Experimental demonstration of bandwidth reduction using Nyquist shaped PSK for flexible udWDM

Nyquist shaped PSK for flexible udWDM is proposed. 1.25Gb/s (2.5Gb/s) Nyquist-PSK with a 120° homodyne coherent receiver reduces the used optical bandwidth to 3.75GHz (5GHz) with receiver sensitivity of -48.5dBm at BER=10 -3 .
