Drive‐Efficient GHz‐Rate Binary‐State Updates Enabled by VCSEL Polarization Switching

open access: yesLaser &Photonics Reviews, EarlyView.
Photonic computing needs a compact node that can hold a binary state and update it fast. A vertical‐cavity surface‐emitting laser biased at its polarization‐switching point could serve as one: its two orthogonal linear polarizations are the two states, and a small electrical drive is enough to move the output from one state to the other at gigahertz ...

Ultrahigh Detectivity Colloidal Quantum dot Avalanche Photodetectors Driven by Electron Mobility of the n‐Type Layer

open access: yesAdvanced Electronic Materials, Volume 12, Issue 19, 12 October 2026.
Herein, electron mobility of the n‐type layer is demonstrated to be a key parameter governing detection performance in CQD‐APDs through a comparative study of ZnO nanoparticles (NPs) and ZnO sol–gel (S‐G). The incorporation of ZnO NPs with high electron mobility facilitates efficient extraction of photogenerated electrons, thereby achieving improved ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

open access: yesAdvanced Materials, Volume 38, Issue 51, 11 September 2026.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

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

open access: yesAdvanced 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 ...
