Description
The National Institute of Standards and Technology (NIST) is seeking a polarization-entangled photon source based on spontaneous parametric down-conversion (SPDC). The source must be capable of accepting an external pump laser and generating high-quality polarization-entangled photon pairs. The system should be built using a periodically poled lithium niobate (PPLN) waveguide, which offers efficient nonlinear conversion and compact integration. The source must include the ability to temperature-tune the phase-matching conditions, allowing for precise control over the output wavelengths and optimization of entanglement quality.
Some key requirements include:
• Turnkey alignment-free source
• Photon pairs wavelength centered at 1550 nm with 3 nm bandwidth
• Noise suppression >75 Db
• Fidelity >98%
• Pair generation rate >2 MHz
• Two-photon interference visibility >98%
• Capability to connect an external temperature controller
• Capability to take an external pump laser
• Continuous Operation: Designed for reliable 24/7 operation
