Cross-polarized photon-pair generation and bi-chromatically pumped optical parametric oscillation on a chip

This paper, entitled "Cross-polarized photon-pair generation and bi-chromatically pumped optical parametric oscillation on a chip" reports frequency mixing between orthogonal polarization modes in a compact integrated microring resonator and demonstrate a bi-chromatically pumped optical parametric oscillator. Operating the device above and below threshold, orthogonally polarized beams and photon pairs are respectively generated. The study can find applications, for example, in optical communication and quantum optics.
