Continue development of a Compact Transmitter Module (CTM). Modules will be voltage controlled to adjust wavlength using temperature and drive current settings. The electronics will be designed to be space qualifiable. Modules will be designed and manufactured capable of operating at 1.2x µm and 1.57 µm. Reductions in size, weight and power will be pursued using either small conventional coolers or thin film thermoelectric coolers (nano-coolers) to replace the conventional larger TEC. Weight reductions will be explore by using alternative which are composites of Aluminum Silicon (AlSi) and Aluminum Graphite.
