Abstract

Optical communications can be an attractive alternative to microwave technology in commercial and military space communications, particularly when the data rate required is high. System analysis at the optical frequencies often differs significantly from that at lower frequencies due to the vastly different technology of sources, modulators and receivers and also due to the important role that nonclassical (quantum) noise plays in determining system performance. In this paper important optical communication system architectures and critical system and technology issues that affect system designs will be examined. Coherent (heterodyne or homodyne) systems will be compared to incoherent (direct detection) systems in the context of space communications. Examples will be drawn from current state-of-the-art technologies and projected future technologies.
