High‐Performance 535‐nm Green Laser Diode Enabling Free‐Space and Underwater Optical Links

ABSTRACT There is a continuous growing demand for visible light communication (VLC) with high‐speed and low‐latency in both free‐space and underwater environments. However, green laser diodes (LDs) remain constrained by the long‐standing “green gap”, where material quality and de...

Ultraviolet‐Induced Band Engineering in Black Phosphorus/Gallium Nitride Heterojunction Toward High‐Performance Broadband Photodetection

ABSTRACT Broadband photodetectors that combine ultraviolet sensitivity with visible and near‐infrared response are important for multispectral optoelectronic sensing. However, the performance of these photodetectors is often limited by weak interfacial carrier separation and inef...
