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 ...

Researchers have developed a new way to control and manipulate optical signals by embedding a liquid crystal layer into waveguides created with direct laser writing. The new devices enable ...

“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 ...

Quantum computing represents a potential breakthrough technology that could far surpass the technical limitations of modern-day computing systems for some tasks. However, putting together practical, ...

Portland, Ore. – Cornell University says it has fabricated the components necessary for silicon optical computers that use light instead of electrons. “Photonic microchips are now a reality,” said ...
