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 ...

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 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 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 ...

A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical ...

A teams of researchers from South Africa and Tunisia have demonstrated that adding light patterns to optical communications can bring significant bandwidth benefits. This new dimension in light ...

The basics of digital logic are pretty easy to master, and figuring out how the ones and zeroes flow through various kinds of gates is often an interesting exercise. Taking things down a level and ...

Researchers from the University of Southampton (UK), and the Institut d'Optique in Bordeaux (France) have devised a new approach for controlling light in a silicon chip by bringing the concept of ...
