Abstract:

In this paper, we describe progress in the development of the Multiple Quantum Well retromodulator for compact, covert data transfer which is uniquely suited to unmanned vehicles. Device power draw is quite low and can be sun-powered with possible laser light augmentation in some strategies. Carrier wavelengths are in the infrared so interference is not an issue and shutter speeds can support up to 10 Mbps. Progress in demonstrating solar-powered burst communications for a UAV in flight will be presented. Alternative power schemes using photovoltaics will be presented to show how a low cost, low power communications terminal can be configured.
