Researchers have developed a new method for light and matter interaction, paving the way for the production of ultrathin silicon solar cells. The University of California, Irvine (UC Irvine) team's ...

For decades, scientists have used near-infrared light to study the brain in a noninvasive way. This optical technique, known as fNIRS (functional near-infrared spectroscopy), measures how light is ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...
