Paper Abstract

Ideal detection techniques for laser communication are briefly reviewed. Laser communication systems using homodyne Manchester BPSK (MBPSK) and optically preamplified (OP) DPSK are compared on the basis of receiver sensitivity, temporal, spatial, and hardware requirements. It is found that a reduction of optical parts count at the receiver and a reduction in prime power also accompany the 3 dB benefit of homodyne. This occurs, however, at the expense of a more complex, although likely off-the-shelf, local oscillator laser and a doubling of the required signal bandwidth.
