Advr Inc, based in Bozeman, MT, specializes in engineered nonlinear optical technologies, offering a wide range of frequency conversion chips and devices using bulk and waveguide periodically poled LN, MgLN, and KTP materials. Their products enable second harmonic generation (SHG), sum frequency generation (SFG), difference frequency generation (DFG), spontaneous parametric down-conversion (SPDC), and third harmonic generation (THG) across UV to IR wavelengths.
With a unique line of broadband visible to NIR phase modulators based on KTP waveguides, Advr Inc provides higher power handling capabilities while maintaining low Vpi and broadband modulation. They also offer X-cut APE LN modulators for low loss C-band and O-band operation. Additionally, Advr Inc's waveguide-based devices allow for high generation rates of photon pairs, with GHz per mW of pump for Type 0 interactions and MHz per mW of pump for Type II interactions.
