Project Description

High Fidelity Down-Conversion Source for Secure Communications using On-Demand Single Photons
In this NASA SBIR Phase II effort, AdvR will design and build an efficient, fully integrated, waveguide based, source of spectrally uncorrelated photon pairs that will enable accelerated research and development in the emerging field of quantum information science. The key innovation is the use of sub-micron periodically poled waveguides to produce counter propagating photon pairs using quasi-phase matched downconversion. This novel device will provide a high brightness source of downconversion pairs with enhanced spectral properties, low attenuation, and operation in the visible to the mid-infrared spectral region.
