Suppression of Residual Single-Photon Absorption Relative to Two-Photon Absorption in High Finesse Planar Microcavities [PDF]

IEEE Photonics Technology Letters, 2008
Suppression of residual single-photon absorption (SPA) relative to two-photon absorption (TPA) in a high finesse GaAs planar microcavity is explored. The TPA photocurrent becomes larger than the SPA photocurrent as long as the incident continuous-wave optical power exceeds 0.09 mW.

Coherent Perfect Absorption in Deeply Subwavelength Films in the Single-Photon Regime [PDF]

Nature Communications, 2015
AbstractThe technologies of heating, photovoltaics, water photocatalysis and artificial photosynthesis depend on the absorption of light and novel approaches such as coherent absorption from a standing wave promise total dissipation of energy. Extending the control of absorption down to very low light levels and eventually to the single-photon regime ...

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.

Photofluorochromic water-dispersible nanoparticles for single-photon-absorption upconversion cell imaging

Nanotechnology, 2021
Abstract Photofluorochromic diarylethene (DAE) molecules have been widely investigated due to their excellent fatigue resistance and thermal stability. However, the poor water solubility of DAEs limits their biological applications to some extent.

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.
