In one device, photothermal microcavities simultaneously measure light power and wavelength for potential applications in ...

Harvard and PSI scientists have managed to freeze normally fleeting quantum states in time, creating a pathway to control ...

The innovative 3D micro-printed microlaser sensor demonstrates exceptional sensitivity, paving the way for advanced lab-on-a-chip diagnostic applications.

Abstract: The article reports the successful fabrication of GaN-based resonant cavity light-emitting diodes (RCLEDs ... Under light injection condition, longitudinal mode laser was observed at 438 nm, ...

GaN-VCSELs are composed of two layers of special semiconductor mirrors, called distributed Bragg reflectors (DBRs), separated by active GaN-semiconductor layers, which form the optical resonant cavity ...

A compact solid-state single-longitudinal-mode (SLM) Q-switched laser based on a compound cavity is demonstrated. SLM operation is achieved through the enhancement of mode competition (via ...

State Key Laboratory of Electronic Thin Films and Integrated Devices, School of Optoelectronic Science and Engineering, University of Electronic Science and Technology of China, Chengdu, China ...

But cavities, composed of a power and ground plane for example, can have very high Qs. This means even a little bit of coupling from signal paths can drive resonances and give rise to long range noise ...
