Germanium‐Based Mid‐Infrared Integrated Photonics
Laser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Small Structures, Volume 7, Issue 7, July 2026.Magnonic crystals (MCs) are an emerging class of metamaterial structures that manipulate spin‐wave propagation. This study identifies previously unknown, inverse‐designed MCs that achieve large magnonic bandgaps by combining a topology optimization framework with computational micromagnetics.

Molecular Ecology Resources, Volume 26, Issue 5, July 2026.ABSTRACT Given the high levels of endemism, diversity, and increasing anthropogenic impacts in tropical regions, studies on species interactions and ecological networks are urgently needed to understand community responses to environmental change. Increasingly, molecular methods are used to monitor biodiversity and identify species interactions.

Nanophotonics, Volume 15, Issue 11, 13 June 2026.Backward optical parametric oscillation is realized in a submicron‐poled thin‐film lithium niobate microring. By engineering the quasi‐phase‐matching condition, both type‐0 and type‐I degenerate oscillation emerge in the same device and are selectively accessed through temperature tuning, providing a versatile on‐chip platform for polarization‐diverse ...

Unlocking Photodetection Mode Switching from a Simple Lateral Design
Advanced Functional Materials, Volume 36, Issue 44, 1 June 2026.A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and
