Photon Pair Sources
AdvR’s PPKTP waveguides have been used to produce promising results in the field of quantum information. Researchers can use Type 0 and Type II frequency conversion to make advancements
- GHz/mW Pair Generation Rates for Type 0 Interactions
- MHz/mW Pair Generation Rates for Type II Interactions
- Custom Degenerate or Non-Degenerate Interactions
- Common Interaction Included 405 nm -> 810 nm and 775 nm -> 1550 nm SPDC.
- Options for Unpackaged Waveguide Chip, Fiber Coupled Devices, and Timing Compensated Devices
