High-yield single-photon source using gated spontaneous parametric downconversion.
The construction of a single-photon source by use of gated parametric fluorescence is reported with the measurement results of the photon number distribution. A beamlike twin-photon method is used in order to achieve high-collection efficiency. The estimated probability P(1) to find a single photon in a collimated output pulse is 26.5% at a repetition rate of 10 kHz when the effective quantum e...
متن کاملHeralded single-photon source utilizing highly nondegenerate, spectrally factorable spontaneous parametric downconversion.
We report on the generation of an indistinguishable heralded single-photon state, using highly nondegenerate spontaneous parametric downconversion (SPDC). Spectrally factorable photon pairs can be generated by incorporating a broadband pump pulse and a group-velocity matching (GVM) condition in a periodically-poled potassium titanyl phosphate (PPKTP) crystal. The heralding photon is in the near...
متن کاملPhoton-number state on-demand source by cavity parametric downconversion
The authors propose a realizable scheme for an arbitrary photon-number state on-demand source based on parametric downconversion in a doubly resonant photonic cavity. The signal-wavelength resonance serves as storage for signal photons and the idler-wavelength resonance generates time separation between exiting idler photons, enabling photon-number-resolving detection. The counting of idler pho...
متن کاملUltrabroadband coherence-domain imaging using parametric downconversion and superconducting single-photon detectors at 1064 nm.
Coherence-domain imaging systems can be operated in a single-photon-counting mode, offering low detector noise; this in turn leads to increased sensitivity for weak light sources and weakly reflecting samples. We have demonstrated that excellent axial resolution can be obtained in a photon-counting coherence-domain imaging (CDI) system that uses light generated via spontaneous parametric downco...
متن کاملBragg-grating-enhanced narrowband spontaneous parametric downconversion.
We propose a new method to narrow the line width of entangled photons generated from spontaneous parametric downconversion (SPDC). The single structure device incorporates an internal Bragg grating onto a nonlinear optical waveguide. We study theoretically the spectral characteristics of SPDC under two Bragg grating structures. We show that using the Bragg grating with a midway pi-phase shifter...
