Abstract:
There is provided a fiber-based broadband polarization-entangled photon source. The polarization entangled photon pair source module comprises an optical fiber, a pump to couple light into the fiber and one or more suppression filters following the fiber. The optical fiber preferably is a periodically poled silica fiber and the pump is preferably a laser diode pump. The present invention relates to a compensation-free, alignment-free, diode-pumped, broadband, polarization-entangled photon source that is based on a low-birefringence fiber. It has an extremely simple configuration capitalizing on the compensation-free and direct generation capability of a low-birefringence fiber. The source has broad bandwidth, high-quality and polarization-entanglement. The present invention is compact, robust, low-power, low-cost, alignment-free and room-temperature operable, featuring a simple turn-key, plug-and-play operation.

Claim (Index 19):
The module of  claim 18  wherein the one or more suppression filters provide more than 110 dB of suppression to the pump light.
