Abstract :
The potential of heterodyne systems is examined, beginning with a description of a typical optical heterodyne detection system. Sources for coherent systems are reviewed, and frequency agility is discussed. The problem of optical frequency determination and control is addressed. Two approaches for achieving polarization diversity reception are considered. Progress toward applying the techniques described is assessed.<>
