Abstract
The spin-entangled photon emission device comprises a Fabry-Pérot resonator with a solid state optical waveguide integrated on a substrate. Preferably, the device is used in a configuration that makes it possible to tune the resonance wavelength of the Fabry-Pérot resonator by straining or otherwise adjusting the effective optical length of the waveguide. A diamond membrane is located in the Fabry-Pérot resonator. The diamond membrane comprises a photon-source capable of emitting a photon that is entangled with a spin state of the photon source. A first surface of the diamond membrane abuts to a first mirror of the Fabry-Pérot resonator. The optical waveguide has a first end facet bonded to a first surface of the diamond membrane. The first mirror of the Fabry-Pérot resonator is formed by a reflector on the second surface of the diamond membrane. The second mirror of the Fabry-Pérot resonator is formed by a reflector on a second end facet of the optical waveguide or inside the optical waveguide.
