AdvR produces engineered nonlinear optical chips and devices using bulk and waveguide-based materials. Products include frequency converters for SHG, SFG, DFG, and downconversion interactions in a suite of materials (MgO:LN, LN, and KTP) for custom interactions at UV, visible, and IR wavelengths. AdvR’s unique offering of KTP waveguide devices are perfect for high-rate photon pair generation, while undoped LN waveguide devices allow for low loss and high efficiency quantum frequency conversion. AdvR also offers broadband fiber coupled phase modulators for high power visible to NIR operation. Applications include QuIST, atom and ion sensing, remote sensing, and basic research.
