Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly ...

The vortex is ubiquitous in nature, spanning from the galaxy, ocean flow, to phyllotaxis. In electromagnetic wave, the vortex can be found in spiral wavefront profiles, representing the orbital ...

Recently, the Laboratory of Micro and Nano Engineering, School of Engineering Science, University of Science and Technology of China (USTC) has made important progress in the field of structural ...

The knots in your shoelaces are familiar, but can you imagine knots made from light, water, or from the structured fluids ...

In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing ...

A high energy electron in circular/spiral motion radiates vortex photons in the entire wavelength range from the radio-wave to the gamma-rays, researchers have shown theoretically and experimentally.
