Refractive index measurement is at the heart of optical science, influencing everything from lens design to material characterization. Modern techniques span from classical prism-based methods to ...

Researchers at Beijing University of Chemical Technology (BUCT) and BOE Technology Group Co., Ltd. (BOE) have developed a novel type of transparent organic–inorganic hybrid photoresist with highly ...

Physicists at Harvard University in the US have built a silicon waveguide that exhibits a refractive index of, or close to, zero when operating at near-infrared telecom wavelengths. The waveguide can ...

The Brix scale, derived from the refractive index of a solution at 20 degrees Celsius (68 Fahrenheit), is widely known. Originally, it was established by determining the weight percentage of sucrose ...

(PhysOrg.com) -- Scientists at the University of California, Berkeley, have for the first time engineered 3-D materials that can reverse the natural direction of visible and near-infrared light, a ...

A team of scientists has uncovered a crystal that can be reshaped and programmed using ordinary light, opening a new path for ...

A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped ...
