Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors ...

Maybe you’ve seen an influencer gliding an illuminated red wand across their face or a glowing Jason-like mask on a beauty-savvy friend — these are LED (light-emitting diode) devices meant to ...

Inorganic LEDs are light-emitting diodes (LEDs) made from a crystalline semiconductor. The optical emission wavelength can be selected by varying material composition. Example active regions ...

Red light therapy doesn’t hurt or burn the skin, nor does it expose the user to UV rays. Research shows that red light therapy, when used correctly, can help in smoothing skin, improving elasticity, ...

SAXONBURG, Pa., June 13, 2025 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, today launches the SES18-880A-190-10, a high-power 880 nm single-emitter laser diode on ...

An organic light emitting diode (OLED) with a linearly polarized white light emission is demonstrated using a nanograting structure. The aluminum based grating structure is fabricated by laser ...

X-Fab has improved 25V isolation for better SPAD integration in its 180nm XH018 fab process. 4×3 SPAD arrays: Original Isomos1 and new Isomos2 (right) SPADs – single-photon avalanche diodes – are used ...

The API failed to deliver the resource. A handful of residents in the Woodland Historic District in downtown Phoenix have raised concerns over a potential light rail expansion.

This study delves into the intricate behaviors of degradation in AlGaN-based UV-C light-emitting diodes (LEDs) undergoing constant current stress and maintaining a constant heat sink temperature over ...

OLED stands for "organic light-emitting diode." QLED (according to Samsung) stands for " q uantum dot LED TV." OLED is a fundamentally different technology from LCD, the major type of TV.

A new and general approach to achieving efficient electrically driven light emission from a Si-based nano p-n junction array is introduced. A wafer-scale array of p-type silicon nanotips were formed ...
