Time‐Modulated Optomechanics Reveal Energy Flow and Inelastic Interactions Between Acoustic Phonons in Nanomembranes

Laser &Photonics Reviews, EarlyView.
Temporal interfaces are abrupt refractive index changes used in time‐varying optics, but also transitions to nonequilibrium states. This work explores the inelastic scattering of time‐varying light by nonthermal acoustic phonons in the vicinity of temporal interfaces.

Microfluidic Molecular Diagnostic Chips: Functional Modules, Integration Strategies, and Emerging Applications

Small Methods, EarlyView.
This comprehensive review delivers an engineering‐centric analysis of microfluidic molecular diagnostic chips, breaking them down into foundational modules from fluid manipulation to bio‐sensing. Beyond chip design, it evaluates sample‐to‐answer integration strategies and commercial readiness levels.

Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

Journal of Microscopy, EarlyView.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Germanium Single Crystals for Photonics

Crystals
Germanium (Ge) is a system-forming material of IR photonics for the atmospheric transparency window of 8–14 µm. For optics of the 3–5 µm range, more widespread silicon (Si), which has phonon absorption bands in the long-wave region, is predominantly used.

Femtosecond‐Laser‐Induced Selective Etching in a Mid‐Infrared Glass

Advanced Photonics Research, Volume 7, Issue 11, November 2026.
Using femtosecond‐laser‐assisted chemical etching in 1 mol L−1 HCl, selective etching is demonstrated for the first time in a MIR‐transmitting gallate glass, yielding etching rates exceeding 4000 µm h−1 and aspect ratios up to ~15. Thermal modeling and annealing experiments suggest the involvement of oxygen‐related defects in the etching mechanism ...

Sound offset responses become highly informative in the auditory cortex

The Journal of Physiology, Volume 604, Issue 21, Page 8702-8720, 1 November 2026.
Abstract figure legend Using large datasets of neural responses to diverse sounds recorded across four stages of the mouse auditory system (depicted and colour‐coded on the left), offset responses occurring after the termination of each sound (time window indicated by the orange shaded area superimposed with activity traces) were characterized and it ...

Lensless acousto-optical convolver

Electronics Letters, 1978
A lensless acousto-optical convolver has been realised with surface acoustic waves, which relies on a technique of polarisation discrimination detection of the diffracted light. A polariser may, then, filter the light signal directly in the Fresnel field, thus allowing realisation of a strictly compact device that retains properties of easy adjustment ...
