Controlling light is an important technological challenge—not just at the large scale of optics in microscopes and telescopes ...

Light can be sculpted into countless shapes. Yet building optical devices that can simultaneously manipulate many different ...

The Sun has captivated humanity for millennia. And yet, despite being our closest star, studying it is not easy. Its blinding ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

As nights have gotten brighter, the list of health problems linked to artificial lighting has gotten longer, from insomnia to cancer. Lighting in urban areas like Chicago (shown) has gotten brighter ...

Each Wasatch Photonics volume phase holographic (VPH) grating produced is an original, with consistent performance from one grating to the next. Our proprietary processes minimize stress, resulting in ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Abstract: In this paper, the sensor containing light coupling into surface plasmon resonance (SPR) structure via volume diffraction grating was studied. A film made of amorphous chalcogenide materials ...

Abstract: The continuous miniaturization of semiconductor devices has increased the demand for advanced process control technologies. This process requires real-time measurement systems to monitor ...
