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 GaAsAlsub 0.3Gasub 0.7As 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.
