Efficient and Compact Semiconductor Laser Transmitter Modules, Phase I

Completed Technology Project

Project Introduction

Efficient and Compact Semiconductor Laser Transmitter Modules, Phase I
Develop a Compact Transmitter Module (CTM) capable of operating at 1.26 µm, 1.57 µm and at 2 µm complete with all drive and control electronics for the TEC and the laser diode itself reducing size, weight and power while improving performance and reliability. The first part of the approach is to incorporate the electronics within the same hermetically sealed enclosure with the laser chip and associated optics. EM4 will take this basic design and make modifications to reduce size, weight and power consumption using thin film thermoelectric coolers (nano-coolers) to replace conventional TEC. Weight reductions will be realized by using alternative which are composites of Aluminum Silicon (AlSi) and Aluminum Silicon Carbide (AlSiC) More »
