Vision, microscopy, imaging, optical data projection and storage all depend on focusing of light. Dynamic focusing is conventionally achieved with mechanically reconfigurable lenses, spatial light ...

Researchers have devised a new approach for controlling light in a silicon chip by bringing the concept of spatial light modulation to integrated optics. Silicon photonics are forming the backbone of ...

A simple, cheap, and highly effective approach to achieve large tuning range of optical transmittance through harnessing surface wrinkling–cracking patterns on polydimethylsiloxane (PDMS) films. The ...

Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a novel framework for monitoring structural vibrations using diffractive optical processors. This new ...

Bespoke manipulation of light by Steve Johnson's group could find uses in cellphone lenses, smart-car sensors, optical fibers. Mathematicians at MIT, Cambridge, Ma, have developed a new computational ...

A flexible optical identifier uses polarized emission from self-assembled crystal films to create two stable states that support tri modal authentication and improve reliability in secure device ...

An optical illusion is a visual phenomenon where our perception of thinking about an image differs from objective reality. This image is seen as a Radiating Wavy Pattern Optical Illusion that appears ...
