Optical time-division channel drop and demultiplexing at 4:1 bit rate using a single Mach-Zehnder modulator in a fiber loop

Abstract

A new optical time division demultiplexing technique is presented using a Mach-Zehdner modulator in a fiber loop mirror. Bit-error rate measurements show high- performance 4:1 demultiplexing of an 80 Gb/s optical signal to 20 Gb/s channels.
