Measurement-induced collective vibrational quantum coherence under spontaneous Raman scattering in a liquid [PDF]

Nature Communications, 2023
Spontaneous vibrational Raman scattering is a ubiquitous form of light–matter interaction whose description necessitates quantization of the electromagnetic field.

Differentiation of glioblastoma tissues using spontaneous Raman scattering with dimensionality reduction and data classification. [PDF]

Front Oncol, 2022
The neurosurgery of intracranial tumors is often complicated by the difficulty of distinguishing tumor center, infiltration area, and normal tissue. The current standard for intraoperative navigation is fluorescent diagnostics with a fluorescent agent ...

Few-Mode Fiber with Low Spontaneous Raman Scattering for Quantum Key Distribution and Classical Optical Communication Coexistence Systems [PDF]

Sensors
In this paper, the theoretical model of spontaneous Raman scattering (SpRS) in few-mode fiber (FMF) is discussed. The influence of SpRS on quantum key distribution (QKD) in FMF is evaluated by combining wavelength division multiplexing (WDM) and space ...

Intercore spontaneous Raman scattering impact on quantum key distribution in multicore fiber [PDF]

New Journal of Physics, 2020
We propose a theoretical model to quantitatively estimate the intercore spontaneous Raman scattering (ICSRS) in multicore fiber based on intercore crosstalk. We analyze the properties of ICSRS through numerical simulations.

Revisiting spontaneous Raman scattering for direct oxygen atom quantification [PDF]

Optics Letters, 2021
In this Letter, the counterintuitive and largely unknown Raman activity of oxygen atoms is evaluated for its capacity to determine absolute densities in gases with significant O-density. The study involves C O 2 microwave plasma to generate a self-calibrating mixture and establish accurate cross sections for

Broadband Coherent Raman Scattering: Excitation Architectures and Operating Regimes [PDF]

Molecules
Coherent Raman scattering (CRS) techniques such as coherent anti-Stokes Raman scattering (CARS) provide chemically specific vibrational contrast with signal levels far exceeding spontaneous Raman scattering (SpRS). Extending these to broadband excitation
