ppKTP Waveguide
ppKTP Waveguide serves as a generator of quantum light for integrated technologies.
Compared to bulk crystals, they have the advantage of enhanced pair generation efficiency, typically by one order of magnitude. In our waveguides, the light is self-contained inside a core of 15-30 microns in diameter. These devices are beneficial for highly efficient single-pass frequency conversion and pair generation. PPKTP Waveguide offer improved brightness in quantum applications, allowing miniaturization of quantum light sources and compatibility with all-fiber systems and integrated photonics.Technical Data
