Abstract: Improved optical modulation is provided in materials which are both piezoelectric and optically isotropic. This enables an acousto-optic modulator configuration with a longitudinal interaction geometry for the optical and acoustic waves which also provides a large acceptance angle. Preferably, the acoustic modulation is at a frequency that corresponds to a mechanical resonance of the modulator window.

Abstract: Devices and/or methods provided herein relate to providing conversion of photons between an optical domain and a microwave domain. An electronic structure can comprise a resonator assembly comprising a microwave resonator and an optical resonator, an optical pump waveguide that transmits an optical pump input to the resonator assembly, and an optical signal waveguide, separate from the optical pump waveguide, that transmits an optical signal relative to the resonator assembly. The electronic structure further can comprise a microwave signal waveguide that transmits a microwave signal relative to the resonator assembly. The optical pump waveguide can comprise a delay portion that delays receipt of the optical pump input to the resonator assembly through the optical pump waveguide to a time after reduction of a majority of decoherence of the resonator assembly caused by scattering of a portion of the optical pump input, which portion does not enter the optical pump waveguide.

Abstract: A laser source includes a first laser device configured to generate a first laser beam having a first wavelength, a second laser device configured to generate a second laser beam having a second wavelength, which is different from the first wavelength, and a non-linear crystal configured to receive simultaneously the first and second laser beams and to generate a third laser beam that has a third wavelength, which is larger than each of the first and second wavelengths. The non-linear crystal has a length and a width, and a variable poling period is distributed across the width so that the third wavelength varies within a given wavelength range based on an incident position of the first and second laser beams along the width of the non-linear crystal.

Abstract: The invention relates to a single-photon generator and a single-photon generating method, which theoretically makes it possible to precisely generate a single photon in real time. A three-level lambda system is formed of a coupled quantum dots group, which is a set of a number of coupled quantum dots where a couple of quantum dots having different ground quantum levels are coupled. The entirety is made in an exciton ground state through illumination with first excitation light. Then, the number of photons in the Raman scattering light through illumination with second excitation light is detected, and a single excited Dicke state is achieved. After that, a single photon is generated accompanying the transition from the single excited Dicke state to the exciton ground state through illumination with third excitation light.
