Twisted sisters: light with OAM values of +1 (top) and 0 (bottom) before (left) and after (centre) passing through the doughnut wave guide. The column on the right shows the inference of the two ...

Waveguides are structures designed to direct and control the propagation of electromagnetic waves from one point to another. They play a crucial role in various fields, including telecommunications, ...

(Nanowerk News) For the first time, researchers have successfully generated strongly nonclassical light using a modular waveguide-based light source. The achievement represents a crucial step toward ...

When two black holes merge or two neutron stars collide, gravitational waves can be generated. They spread at the speed of ...

Waveguides generate digital images directly in the field of vision and enable smart glasses such as the Meta Ray-Ban. We explain the technology behind them. Waveguides, as they are known in German, ...

Engineers at the University of California San Diego have developed the thinnest optical device in the world--a waveguide that is three layers of atoms thin. The work is a proof of concept for scaling ...

Researchers have succeeded in making the thinnest ever optical device in the form of a waveguide just three atomic layers thick. The device could lead to the development of higher density ...

Researchers have successfully generated strongly nonclassical light using a modular waveguide-based light source. By combining a waveguide optical parametric amplifier (OPA) module created for quantum ...

Researchers in the US have come up with a microfluidic waveguide that relies on the thermal gradient across its core and cladding liquids to channel light. "One advantage of a liquid waveguide is that ...

Light is well known to exhibit both wave-like and particle-like properties, as imaged here in this 2015 photograph. What's less well appreciated is that matter particles also exhibit those wave-like ...
