(Nanowerk News) 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 ...

High-power laser diodes constitute a critical element in contemporary photonic systems, delivering efficient, compact, and reliable sources of coherent light for a variety of applications ranging from ...

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 ...

PITTSBURGH—Charged particle accelerators have been a central tool of basic physics research for almost a hundred years, perhaps most famously as “atom smashers” for understanding the elementary ...

Researchers embedded a liquid crystal layer into a waveguide that was created with direct laser writing (pictured). The resulting hybrid device can be used to change the polarization of light ...
