Bright Polarization Entangled Photon Source

The United States Air Force is seeking a Bright Polarization-Entangled Photon Source. The required source must provide a uniquely high number of entangled pairs per second, a turn-key, alignment-free solution for use in field environments, and be fully compatible with the suite of Oz Optics automated rotation optics and tomography modules already present in AFRL laboratories. The Government has determined that Oz Optics Limited is the only company that can satisfy the minimum technical specifications for this requirement. • The source must generate high-quality polarization-entangled photon pairs within a narrow telecom bandwidth centered at 1550 nm. • The unit must be a turn-key, alignment-free bright source operating at room temperature. • The photon pairs shall be generated through a Sagnac interferometric configuration and directly injected into two single-mode output fibers without using a wavelength splitter. • The output ports must be accessed through two FC/APC adaptors installed on the front panel, delivering the photon pairs within 9/125 μm single-mode fibers.
