  • Polarization-entangled photon pair source and method for the manufacture thereof
    Patent number: 9075283
    Abstract: An entangled photon pair source including: a quantum emitter having a ground state, two degenerate states that have one elementary excitation and different spins, and a state having two elementary excitations; a first optical cavity, wherein the quantum emitter is inserted; and a second optical cavity coupled with the first cavity. The geometry of the first and second cavities, and force of coupling thereof, are selected such that the whole formed by both coupled cavities has a first pair of polarization-degenerate modes, that are resonant with transitions between the state having two elementary excitations and the two degenerate states having one elementary excitation from the quantum emitter, and a second pair of polarization-degenerate modes that are resonant with transitions between the degenerate states, having one elementary excitation, and the ground state.
