Pulsed Sagnac polarization-entangled photon source with a PPKTP crystal at telecom wavelength
Rui-Bo Jin, Ryosuke Shimizu, Kentaro Wakui +6
We demonstrate pulsed polarization-entangled photons generated from a periodically poled (PPKTP) crystal in a Sagnac interferometer configuration at telecom wav…
Efficient detection of a highly bright photon source using superconducting nanowire single photon detectors
Rui-Bo Jin, Mikio Fujiwara, Taro Yamashita +6
We investigate the detection of an ultra-bright single-photon source using highly efficient superconducting nanowire single-photon detectors (SNSPDs) at telecom wavelengths. Both t…
Widely tunable single photon source with high purity at telecom wavelength
Rui-Bo Jin, Ryosuke Shimizu, Kentaro Wakui +2
We theoretically and experimentally investigate the spectral tunability and purity of photon pairs generated from spontaneous parametric down conversion in periodically poled $\mat…
Entangled state generation with an intrinsically pure single-photon source and a weak coherent source
Rui-Bo Jin, Ryosuke Shimizu, Fumihiro Kaneda +3
We report on the experimental generation of an entangled state with a spectrally pure heralded single-photon state and a weak coherent state. By choosing group-velocity matching in…
Nonclasscial interference between independent intrinsically pure single photons at telecom wavelength
Ruibo Jin, Kentaro Wakui, Ryosuke Shimizu +7
We demonstrate a Hong-Ou-Mandel interference between two independent, intrinsically pure, heralded single photons from spontaneous parametric down conversion (SPDC) at telecom wave…
