Single Photon Quantum Frequency Conversion

Single Photon

AdvR offers a line of Undoped LN waveguides for high efficiency single photon conversion. These waveguides can convert single photons from visible wavelengths to the telecom from low loss transmission, or from telecom to visible for efficient detection and interactions with atoms.

On-chip features including mode-filters and WDMs allow for efficient fiber coupling wavelengths through separate ports.
