SBIR/STTR Award attributes
The overall goal of this SBIR program is to develop waveguide-based, robust, high-rate, entangled photon pair sources suitable for use in space. These waveguides, fabricated at AdvR utilize periodic poling for efficient quasi-phase matched (QPM) spontaneous parametric downconversion (SPDC) of high energy pump photons into two lower energy signal and idler photons. AdvR’s approach is enabled by a demonstrated expertise in developing and manufacturing periodically-poled waveguides optimized for specific nonlinear interactions in conjunction with a demonstrated track record of system level packaging, environmental testing, and quantum characterization of SPDC sources.
