    摘要: Various embodiments of the present invention are directed to compact systems for generating polarization-entangled photons. In one embodiment of the present invention, a polarization entangled-photon state source comprises a single transmission layer configured for transmitting electromagnetic radiation. The transmission layer includes a beamsplitter and a down-conversion device, both of which are configured to convert a pump beam into first and second signal beams and first and second idler beams. The transmission layer also includes a mode converter configured to invert electric and magnetic field components of both the first signal beam and the first idler beam, and a combiner configured to receive the first and second signal beams and the first and second idler beams and output the first and second signal beams and the first and second idler beams in an entangled polarization states.
