Product information "EPS-1000 Broadband Polarization-Entangled Photon Source"

1530-1580 nm; Wavelength Accuracy ±2 nm; Biphoton Bandwidth 60->120 nm; Pair-generation Rate 1-4x106 Pairs/s; Coincidence-to-accidental Ratio 100-1000; Signal/Idler Sum Frequency Bandwidth 0.1-0.4 nm

OZ Optics’ EPS-1000 fiber-based device is a compact, robust, and alignment-free source of broadband polarization-entangled photon pairs. Based on periodically-poled silica fiber (PPSF) technology, it features turn-key, room-temperature operation, and needs little maintenance. The all-fiber design makes it environmentally stable for challenging applications such as space-based instruments.

It generates high-quality polarization-entangled photon pairs at telecom wavelengths with more than 80 nm of bandwidth. This unit comes with a built-in optical switch to allow the user to direct the light either to a common output port or to a built-in wavelength division multiplexor to have the signal and idler photons of the entangled photon pairs separated to two output ports.

This ideal entanglement source has myriad applications in quantum information processing, quantum sensing, and WDM-based quantum key distribution networks.
