AdvR offers highly efficient and low loss RPE PPLN waveguide-based devices for quantum frequency conversion. These devices can be configured for downconversion with a DFG nonlinear interaction and for upconversion with a SFG nonlinear interaction. Downconversion allows for a visible-NIR photon to be converted to telecom wavelengths for low loss transmission over fiber. Upconversion allows for a telecom signal to be converted to visible-NIR to interact with distributed quantum nodes, computers, and sensors. On-chip features like WDMs and mode filters allow minimal loss of the signal photon in a fully fiber coupled package while highly efficient RPE PPLN waveguides allow for near 100% conversion efficiency within the waveguide. Example downconversion and upconversion interactions have been shown below, but custom wavelength interactions are available.
