Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review

Advanced Science, EarlyView.
Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

InAlGaP vertical cavity surface emitting lasers (VCSELs): processing and performance [PDF]

Conference Proceedings. 1997 International Conference on Indium Phosphide and Related Materials, 2002
The performance of AlGaInP based visible VCSELs has been advanced with the application of new heterostructure designs and the technique of selective oxidation. Improved performance at elevated temperatures as well as high wallplug efficiency, low threshold devices have been demonstrated for devices operating in the 670-680 nm region.

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

Laser &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

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 ...
