QEPS-1550-TYPE-II: Quantum Entangled Photon Source

Quantum entangled photon source, QEPS-1550 TYPE-II, is an all fiber-based C/L band quantum light source producing entangled photon pairs at 1550 nm. It is based on PPLN Ti-diffusion optical waveguide and features Type-II QPM. The quantum entangled photon pairs are generated through the process of Spontaneous Parametric Down Conversion (SPDC) at degenerate condition and then separated into the two telecommunication channels with temporal walk-off compensation between them.
