1570 nm Type-II SPDC Waveguide Chip Submount, w/Fiber Pigtailed, 20 mm SM Mini Isolator The coupler is a 2x2SPDC 1570 20 SP is a 20 mm length Periodically Poled Lithium Niobate (PPLN) waveguide chip designed to operate at 1570 nm. This chip may be used for Spontaneous Parametric Down Conversion (SPDC) to create a pair of polarization correlated photon pairs for Quantum Light Source (QLS) applications. Due to its well confined waveguide structure in Z cut Lithium Niobate, the SPDC 1570 20 SP allows high power density to enhance the frequency conversion
