Abstract

The prospects of using Coherent Communication techniques is -to increase the inlorniation Capacity of an optical link, which has been widely appreciated for more than 20.years. Earlier, in optical fiber communication systems, ono±'1 intensity modulation and direct photo detection were most commonly ado— pted. In these systems, the receiver sensitivity is limited by the detector and amplifier noi8es. Indeed optical communication systems which use heterodyne or homo—dyne detection are common— ly referred as "Coherent Communication Systems" .
