Researchers have designed the first theoretical model that describes the occurrence of multiple solitary optical waves, referred to as dark photovoltaic spatial solitons. The findings by Yuhong Zhang, ...

Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

“We’ve laid the groundwork in the past and shown it’s possible to guide light through liquid channels,” said Holger Schmidt, associate professor of electrical engineering at UCSC. “But this is the ...

Triumphal arc: waveguide is a victory for X-ray optics Physicists in Germany have steered beams of X-rays around corners by carefully shining them along extremely narrow channels carved into a thin ...

Scientists have performed simulations to help understand the occurrence of multiple solitary optical waves that are used to reconfigure optical beams. Researchers have designed the first theoretical ...
