Paper Abstract

A semiconductor laser phased-array transmitter is described that operates by coherently combining the output of many semiconductor laser amplifiers to form a near-diffraction-limited beam in the far field with sufficient power for most free space optical communications applications. Because the outputs are coherently combined, modulation formats requiring coherent detection can be used with this transmitter. Results are presented on the operation of the phased array and on preliminary communications experiments conducted with this transmitter.
