Description: This overall STTR program will lead to the development of a bandwidth tailored pump source for high purity photon pair generation. Spontaneous parametric down conversion can be used to generate high purity photon pairs at wavelengths of interest to NASA and the broader scientific community. However, these sources are highly dependent on pulsed pump laser parameters. Traditional pulsed laser sources are large, power hungry, and not sufficiently robust for deployment. This project aims to take advantage of compact fiber lasers with precisely tuned frequency conversion to generate appropriate bandwidths for high purity photon pair generation. The proposed low SWaP performance is enabled by waveguide-based components fabricated by AdvR in a variety of nonlinear substrates for highly efficient upconversion for pump preparation, and downconversion for high spectral purity pair generation.
