Nanometer-precision measurements of geometric fluctuations via momentum-filtered spectroscopy

Applied Physics Express
In this work, we report ultra-sensitive detection of geometric fluctuations of semiconductor nanostructures using momentum-filtered spectroscopy. Our strategy is developed based on angle-resolved photoluminescence/absorption spectroscopic imaging ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Dirac Cones and Room Temperature Polariton Lasing Evidenced in an Organic Honeycomb Lattice

Advanced Science
Artificial 1D and 2D lattices have emerged as a powerful platform for the emulation of lattice Hamiltonians, the fundamental study of collective many‐body effects, and phenomena arising from non‐trivial topology.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

Advanced Physics Research, Volume 5, Issue 7, July 2026.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Neural Network–Based Depth Retrieval of Fluorescent Targets From Wide‐Field Fluorescence Intensity Images in Scattering Tissues

Journal of Biophotonics, Volume 19, Issue 7, July 2026.
A convolutional neural network (CNN) model accurately predicts the depth of dual near‐infrared dyes, Indocyanine Green (ICG) and IRDye 800, within tissue‐mimicking phantoms and a tumor‐bearing mouse. ABSTRACT Fluorescence imaging (FI) is widely used in in vivo and cellular studies.

3D‐Printed Structures Versus Drilled Cavities: A Comparison of Microconfinement Methods for Rheological Characterisation of Multicellular Aggregates

Journal of Molecular Recognition, Volume 39, Issue 4, July 2026.
ABSTRACT Three‐dimensional (3D) cell culture systems are increasingly recognised as more physiologically relevant models than traditional two‐dimensional cultures, as they better mimic the native tumour microenvironment and enable the study of complex cellular behaviour. However, applying atomic force microscopy (AFM) to these models is challenging due
