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 ...

Impedance model for the polarization-dependent optical absorption of superconducting single-photon detectors [PDF]

, 2009
We measured the single-photon detection efficiency of NbN superconducting single photon detectors as a function of the polarization state of the incident light for different wavelengths in the range from 488 nm to 1550 nm.

Single- and two-photon absorption induced all-optical control of gallium selenide integrated silicon nitride photonic devices in the 700–800 nm wavelength range

APL Photonics, 2023
In this work, we report single- and two-photon absorption (TPA) induced transmission and resonance modulation in a multilayer gallium selenide (GaSe) integrated silicon nitride (Si3N4) waveguide and ring resonator operating in the 700–800 nm wavelength ...

Complete elimination of nonlinear light-matter interactions with broadband ultrafast laser pulses

, 2017
The absorption of a single photon that excites a quantum system from a low to a high energy level is an elementary process of light-matter interaction, and a route towards realizing pure single-photon absorption has both fundamental and practical ...

On the Theory of the Intraband Mechanism of Single-Photon Absorption in Semiconductors, Taking into Account the Effect of Coherent Saturation

East European Journal of Physics
A theoretical analysis of the frequency–temperature dependence of the single-photon absorption coefficient of polarized radiation in narrow- and wide-bandgap semiconductors is conducted, considering intraband optical transitions and including the ...

Stochastic and deterministic absorption in single-photon interference experiments

Physical Review A, 1997
We performed single-photon interference experiments with neutral density filters and slow beam choppers to confirm the difference between stochastic and deterministic absorption and obtained results that agreed with the case of neutron-interference experiments and quantum theory.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

Molecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Realization of a Universal Quantum Gate Set for Itinerant Microwave Photons

Physical Review X, 2022
Deterministic photon-photon gates enable the controlled generation of entanglement between mobile carriers of quantum information. Such gates have thus far been exclusively realized in the optical domain and by relying on postselection.

Raman‐based label‐free microscopic analysis of the pancreas in living zebrafish larvae

FEBS Open Bio, EarlyView.
Forward stimulated Raman scattering (F‐SRS) and epi coherent anti‐Stokes Raman scattering (E‐CARS) allow label‐free discrimination of distinct subcellular structures in the pancreas of living zebrafish larvae. Given the straightforward applicability, we anticipate broad implementation of Raman microscopy in other organs and across various biomedical ...
