This NIST Phase 1 SBIR effort will demonstrate the feasibility of low noise single photon up conversion using KTiOPO4 (KTP) or LiNbO3 (LN) or Stoichiometric LiTaO3 (SLT) periodically poled waveguides and an 1800nm pump for a high efficiency single photon detector. The key innovation is using low noise periodically poled waveguides with a long wavelength (1800nm) pump leading to higher efficiency single photon detectors when used with Silicon-based avalanche single photon detectors (Si-APD). Use of waveguide Sum Frequency Generation (SFG) for 1535nm to 828.5nm up-conversion coupled with inexpensive and very efficient SI-APD technology is expected to significantly increase single photon detection efficiency while maintaining long fiber optic transmission distance for quantum communication networks and quantum-key-distribution (QKD) systems.
