Abstract :
We implemented a compact integrated non-degenerate source which comprises a periodically poled waveguide with highly reflective dielectric mirror coatings to obtain narrowband photon pairs based on type II parametric down-conversion. Our engineered source exploits clustering in the dispersive cavity to restrict the conversion to a predominantly single mode operation with a narrowband linewidth and high spectral purity. The miniaturized monolithic design makes our source a versatile device for various applications in quantum communication and information processing.
