BROADBAND POLARIZATION-ENTANGLED PHOTON SOURCE EPS-1000-3A-1564-9/125-S

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