1550 nm Type-II SPDC Module, 20 mm PM DWDM the SPDC-1550-20-SP allows high powerSPDC 1550 20 M is a fully intergrated Spontaneous Parametric Down Conversion module, incorporated in the module is a 20 mm long Periodically Poled Lithium Niobate (PPLN) waveguide device (SPDC 1550 20 PG) for operating at 1550 nm. When pumped by 775 nm light, this device, Spontaneous Parametric Down Conversion (SPDC), will create polarization correlated photon pairs for Quantum Light Source (QLS) applications. The spectrum can be fine tuned by either
