Abstract

This paper summarizes the design for a laboratory testbed currently under development to evaluate the performance of intersatellite laser crosslinks that directly impose a modulated waveform as an analog signal on the laser carrier. In our analog scheme we use a classical 'bent pipe' satellite implementation, where the RF uplink signal spectrum is frequency translated to directly modulate the laser as an analog waveform, and the received signal at the other end of the optical crosslink is frequency translated to directly modulate the RF downlink. This system design and hardware proof-of-concept addresses the optimum approach to such an analog optical crosslink to facilitate evaluation of its performance.
