Engineering a Multiple-Quantum-Well Modulating Retroreflector for Space Optical Communications: Prototype Development, System Architecture, and Validation Strategy

In 30 seconds

This project develops a modulating retroreflector terminal based on multiple-quantum-well electro-absorption modulators to enable asymmetric, high-speed optical links. The design focuses on integrating the device into a comprehensive opto-electro-thermo-mechanical framework, avoiding isolated device-level assessment. This terminal architecture is specifically engineered to reduce mass, volume, and power requirements for spaceborne platforms requiring active uplink return channels.
