Self-assembling materials called block copolymers, which are known to form a variety of predictable, regular patterns, can now be made into much more complex patterns that may open up new areas of ...

Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the Poisson spot to create stable patterns of light called optical skyrmions, ...

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 ...

The optical radiation force can deform dielectric material surfaces, such as photo-isometric azopolymers, due to their electric susceptibility, and the shape can be controlled by the artificial ...

Researchers used the Poisson spot effect to create stable optical skyrmions with a laser and disc, simplifying studies for ...

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 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 ...

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 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 ...
