High‐Sensitivity, High‐Resolution Stimulated Raman Photoacoustic Spectroscopy Enabled by Continuous‐Wave Intracavity Pump‐Stokes Beams

Laser &Photonics Reviews, Volume 20, Issue 3, 5 February 2026.
High‐sensitivity, high‐resolution stimulated Raman photoacoustic spectroscopy is achieved by coupling continuous‐wave pump and Stokes beams to a high‐finesse optical cavity. This approach successfully resolves the narrow Raman rotational transition S0(0) of H2 with sub‐kHz spectral resolution and attains an unprecedented sensitivity of 0.5 ppm using ...

Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...

Inverse‐Designed On‐Chip Orbital Angular Momentum Mode Converter for Optical Convolution Acceleration

Nanophotonics, Volume 15, Issue 3, 12 February 2026.
This work proposes OAM‐encoded CNN based on cascaded on‐chip OAM converters and multiplexers. The footprint of inverse‐designed converters is 5 μm × 4 μm and the maximum conversion efficiency of OAM reaches 88%. The OAM‐encoded optical CNN was built using this device, achieving 98.0% accuracy on MNIST and 86.1% accuracy on Fashion‐MNIST classification.

The Generation and Control of Irregularly Shaped Perfect Vector Vortex Beams on Hybrid Poincaré Spheres Using All‐Dielectric Metasurfaces

Nanophotonics, Volume 15, Issue 3, 12 February 2026.
Based on an all‐dielectric metasurface with cross‐phase modulation, we achieve the generation and polarization control of integers and fractional order irregular perfect vector vortex beams on the hybrid Poincaré sphere, opening a new avenue for optical field manipulation.
