ABSTRACT: We propose a novel new architecture for a quantum communications laser transmitter that is designed for free-space quantum key distribution (QKD) between a LEO satellite and a ground based system. The transmitter will operate at 778 nm, a wavelength that has previously been analyzed to be the optimum combination 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. BENEFIT: Quantum key distribution (QKD) using polarization modulation with decoy states has increasing interest in the commercial marketplace as a method to enable secure encrypted data transfer. There are already three start up companies addressing this area at 1550 nm for fiber optic system. The proposed quantum communications laser will open new markets for free space QKD as well as continue to develop the planar waveguide hybrid integration technology that can be applied to many different applications that require the development of advanced optical components.
