1570 nm Type-II SPDC Module, 30 mm Fiber Mach-Zehnder Interferometer Narrow Element Gap 45 umSPDC 1570 30 M is a fully intergrated Spontaneous Parametric Down Conversion module, incorporated in the module is a 30 mm long Periodically Poled Lithium Niobate (PPLN) waveguide device (SPDC 1570 30 PG) for operating at 1570 nm. When pumped by 785 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
