Continuous wave coherent light sources have been developed primarily intended for metrology tools in advanced semiconductor manufacturing. 5 W at 266 nm, 150 mW at 213 nm, and 120 mW at 198.5 nm have ...

Lead-halide perovskite nanocrystals (NCs) are promising for fabricating deep-blue (<460 nm) light-emitting diodes (LEDs), but their development is plagued by low electroluminescent performance and ...

Award-winning Romanian director Marian Crișan lines up co-production deal for new drama about traditional Orthodox Holy Fire ceremony 'Holy Light.' ...

Quantum light sources, particularly those based on solid-state emitters, are indispensable components for quantum information technology. Single quantum dots, as a prominent candidate, are leading the ...

As true single-photon sources (SPS) are difficult to produce, most QKD systems developed to date rely on attenuated light sources that mimic single photons, such as low-intensity laser pulses. As ...

A Light That Doesn’t Bounce Back Traditional fNIRS systems measure how light bounces back from the brain’s surface. Light is shone onto the scalp, where some of it penetrates and scatters.

Scientists Produced a Particle of Light That Simultaneously Accessed 37 Different Dimensions It’s got us beat by 34.

The on-chip integration of quantum light sources and nonlinear elements constitutes a major step toward scalable photon-based quantum information processing and communication. In this work we ...

Other light sources, such as bright floodlights and illuminated doorbells to decorative lights in yards and gardens, made up about a quarter of the lights observed.

Night-time satellite images have shown that cities are getting brighter, and light pollution is now recognized as an environmental issue. But how should local governments even begin the work of ...

The connection between light and biology starts with photons striking our retinas, triggering signals that reach a knot of neurons known as the suprachiasmatic nucleus; that knot is a crucial ...

In the Cape Cod National Seashore is the Cape's first lighthouse, in North Truro. Here's a guide on how to visit.
