A microlaser emitting helical light

Researchers recently demonstrated the realization of an integrated microlaser based on a novel design that emits light in chiral modes, thus producing corkscrews of light. An object is said to be chiral if it can be distinguished ...

Mini-projectors -- maximum performance

(PhysOrg.com) -- The number of mini-projector devotees keeps growing. The combination of a new kind of optical structure with high-performance LEDs enables completely new compact and brilliant lighting and projection systems.

The electronic origin of photoinduced strain

(Phys.org)—Multiferroics are in a class of materials that exhibits more than one ferroic order simultaneously. One of the prototypical multiferroics is BiFeO3, an important material because it is one of a few materials ...

Invisible pattern can put a stop to counterfeit designer clothing

There is now a way to differentiate between designer clothing and knockoffs. Chalmers researcher Christian Müller has produced a thread with unique optical properties, which can be used to create invisible patterns in fabrics ...

Bringing color to solar facades

Until now, designers of buildings have no choice but to use black or bluish-gray colored solar panels. With the help of thin-film technologies, researchers have now been able to turn solar cells into colorful creations.
