Quantum Communications Transmitter at 775 nm

Completed Technology Project

Project Description

Quantum Communications Transmitter at 775 nm
We propose a novel new architecture for a quantum communications laser transmitter that is designed for free-space polarization encoded quantum key distribution (QKD) between a spacecraft and a ground based system. The transmitter will operate at 775 nm, a wavelength that has previously been analyzed to be optimize free-space QKD due to the combined influence of atmosphere transition and detection efficiency by Si:APD detectors. Hybrid integration will be used to design and fabricate a compact, rugged, and power efficient module that can meet all of the demanding environment requirements for space based optical components.
