Researchers said these optical vortices could help overcome bandwidth limitations in fibre optic communication, or enhance the optical tweezers that can manipulate atoms. Researchers have created an ...

Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

Scientists have managed for the first time to create a unidirectional device that significantly increases the quality of a special class of transmitted signals in optical communications: optical ...

The Fourth Industrial Revolution is driving exponential growth in data transmission, and cost-effective, ultrafast, and compact optical communication technologies are urgently needed to manage the ...

Topology originated from the classification of geometric structures in mathematics, and have prevailed in a variety of branches of physics, ranging from the early electronic topological insulator to ...

A new optical device might allow astronomers to view extrasolar planets directly without the annoying glare of the parent star. It would do this by “nulling” out the light of the parent star by ...

Researchers have succeeded in printing uniformly sized droplets with a diameter of approximately 100 µm using a liquid film of fluorescent ink. This ink, with a viscosity roughly 100 times that of ...

Light is composed of electric and magnetic fields that oscillate perpendicular to each other. When these oscillations are restricted, say, along a plane, it results in polarized light. Polarized light ...
