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 ...

Engineering Topological Phases with a Traveling‐Wave Spacetime Modulation

Laser &Photonics Reviews, EarlyView.
Time‐varying systems have garnered considerable attention due to their unique potential in manipulating electromagnetic waves. Here, a novel class of topological spacetime crystals with a traveling‐wave modulation is introduced. By manipulating material anisotropy, one can engineer light angular momentum and non‐trivial topological phases characterized

Topological Engineering of High‐Order Exceptional Points Through Transformation Optics

Laser &Photonics Reviews, EarlyView.
A novel framework leveraging transformation optics is introduced for engineering high‐order exceptional points (EPs) in nanophotonic systems. By linking these spectral singularities to physically accessible parameters, this approach enables the design of complex EPs, including third and fourth‐order EPs in coupled nanowire systems.

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 ...

Bridging Classical and Quantum Approaches for Quantitative Sensing of Turbid Media with Polarization‐Entangled Photons

Laser &Photonics Reviews, EarlyView.
This work bridges classical and quantum polarimetry toward quantitative quantum photonic sensing of turbid environments. Theoretical and experimental investigations reveal how polarization‐entangled photonic states evolve in turbid media, uncovering robust trends in entanglement evolution and paving the way for advanced quantum sensing in biomedical ...
