1 W Single‐Mode Large‐Area Edge‐Emitting Laser via Non‐Hermitian Spatial Mode Filtering

open access: yesLaser &Photonics Reviews, EarlyView.
We demonstrate a non‐Hermitian spatial mode filtering approach for achieving high‐power single‐mode operation in large‐area edge‐emitting laser diodes. By symmetrically coupling passive filter arrays to the main lasing waveguide, higher‐order transverse modes are effectively suppressed while preserving the fundamental mode.

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 ...
