VENDOR : optilab


SPDC-1570-5-PG is a packaged 5mm length Periodically Poled Lithium Niobate (PPLN) waveguide chip designed to operate at 1570 nm. This device 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-1570-5-PG allows high power density to enhance the frequency conversion efficiency at wavelengths around 1570 nm when pumped by a 785 nm laser. The spectrum may be tuned by either slightly tuning the pump laser wavelength or by adjusting the temperature of the SPDC-1570-5-PG. Additional operating wavelengths with for Type-II SPDC may be ordered by contacting Optilab directly.
