The Periodically Poled lithium Niobate (PPLN) Waveguide is one of the key devices in quantum communication and quantum information processing. The PPLN waveguide is widely used in up-conversion single-photon detector, satellite-ground quantum communication interface, telecom-band entangled photon source with high rate, etc. What is morLe, the PPLN chip can also be used to produce optical source in the blue-green region, which is often adopted in the field of laser display.
The PPLN-WG-UC50-P5-M5-22 series isspecifically designed for telecom-band single-photon detector. The waveguidesare fabricated withreverse proton-exchanging technique, and applied to convert 1550nm photons to 864nm band with low noise. Both the input and output of the waveguide are fiber-pigtailed, making it easy-to-use.
QuantumCTek also provides customized services of PPLN waveguides for various applications.
