Modular and Automated Workflow for Streamlined Raman Signal Analysis

Journal of Raman Spectroscopy, EarlyView.
This study presents an automated workflow for preprocessing and analyzing Raman spectroscopy data, addressing key challenges such as noise suppression, baseline correction, and peak fitting using Voigt profiles. The method is validated on both synthetic and experimental spectra, demonstrating improved spectral fidelity and peak detection for biomedical

Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

Journal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...

Revealing growth increments in fossil and modern otoliths with backscattered electron imaging

Limnology and Oceanography: Methods, EarlyView.
Abstract Otoliths, the functional earstones of teleost fishes, record growth in the form of microscopic increments, making them key archives of individual life histories. While increment analysis is commonly applied to modern otoliths, studies of fossil (Holocene) otoliths remain limited.

Efficient Robust Spontaneous Parametric Down‐Conversion via Detuning Modulated Composite Segments Designs

Laser &Photonics Reviews, EarlyView.
Detuning modulated composite segmentation (DMCS) enables robust spontaneous parametric down‐conversion with sevenfold improved temperature stability compared to conventional designs, opening new possibilities for stable quantum photon sources. ABSTRACT Spontaneous parametric down conversion (SPDC) holds a pivotal role in quantum physics, facilitating ...

Vortex Beam Lasing from III‐V Nanowires Epitaxially Grown on Silicon‐on‐Insulator

Laser &Photonics Reviews, EarlyView.
An epitaxially grown InGaAs nanowire photonic crystal laser on silicon‐on‐insulator is demonstrated to emit vortex beams carrying orbital angular momentum. Deforming the honeycomb lattice causes the band inversion effect and creates symmetry‐protected bound states in the continuum, enabling single‐mode lasing with a topological charge of −2 ...
