Emission and Absorption of Single Photons by Single Atoms

Research in Optical Sciences, 2012
For quantum networking, we show high-rate single-mode emission of bandwidth-tunable single photons from a single ion, and heralded absorption by the ion of single photons from SPDC photon pairs. The heralded absorption preserves entanglement.

Quantum interference between Raman scattering and single-photon absorption

Chinese Physics B, 2009
A new kind of quantum interference between Raman scattering and single-photon absorption is predicted theoretically, which gives an expanded view of quantum interference. Its potential application is also proposed.

Double-heralded single-photon absorption by a single atom

CLEO: 2014, 2014
We present a single-photon to single-atom interface, where a heralded single photon generated by Spontaneous Parametric Conversion is absorbed by a single trapped ion, subsequently generating a single Raman-scattered photon that heralds the absorption event.

Characterization of optical absorptance in superconducting nanowire single-photon detectors

2013 IEEE 14th International Superconductive Electronics Conference (ISEC), 2013
We present a numerical simulation of the optical absorptance for the superconducting nanowire single-photon detectors (SNSPDs or SSPDs) designed with various layouts by using finite-element analysis software. The simulation results reveal that the electric field concentrated in the superconducting nanowire is enhanced by reducing the filling factor ...

Multi-electron emission from fullerenes upon a single photon absorption

Journal of Physics B: Atomic, Molecular and Optical Physics, 2004
A theoretical model is developed for the treatment of single and coincident multi-electron emission from a C60 molecule following the absorption of a VUV photon. The multi-electron ionization process is viewed as a single electron–photon interaction followed by a sequence of incoherent electron–electron collisions in which the photon energy is ...

Single photon absorption laser facility for single event effect testing

2016 IEEE Canadian Conference on Electrical and Computer Engineering (CCECE), 2016
The laser testing facility for single event effects (SEEs) at the Saskatchewan Structural Sciences Centre, University of Saskatchewan is introduced and its principles of operation described. An ultrafast pulsed laser setup is used to investigate the SEE behavior of microelectronic circuits and devices.

Single Event Effects Characterization Using a Single Photon Absorption Laser

2018 IEEE AUTOTESTCON, 2018
The use of a pulsed laser to analyze a circuit's susceptibility to radiation-induced errors has been a topic of interest to the radiation effects community. Research has shown that while lasers inject charge differently compared to radiation, the errors observed match closely.

Infrared single-photon detection by two-photon absorption in silicon

Physical Review B, 2008
We propose a scheme for infrared single-photon detection based on two-photon absorption at room temperature in Si avalanche photodiodes, where the detected photon's energy is lower than the band gap and the energy difference is complemented by a pump field.

Single-Photon Absorption and Reemission in Two-Level Cold Atoms

The Rochester Conferences on Coherence and Quantum Optics and the Quantum Information and Measurement meeting, 2013
With narrow-band heralded single photons, we demonstrate that the single-photon absorption and reemission processes in a two-level atomic ensemble can be coherently controlled by shaping the incident photon temporal waveform.
