Modulating Retroreflector Architecture Using Multiple Quantum Wells for Free Space Optical Communications
Abstract
In this paper, the authors describe a demonstration using a Multiple Quantum Well modulator combined with an optical retroreflector that supported a high-speed, free space optical data link. Video images were transmitted over an 859-nanometer link at a rate of 460 kilo bits per second, where rate of modulation was limited by demonstration hardware, not the modulator. Reflection architectures for the modulator were used; transmission architectures also were investigated but are not discussed in this paper. The modulator was a GaAs/Al(sub 0.3)Ga(sub 0.7)As quantum well that was designed and fabricated for use as a shutter at the Naval Research Laboratory. These may be the first results reported demonstrating a high-speed, free space optical data link using multiple quantum well shutters combined with retroreflectors for viable free space optical communications.
