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 ...

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 ...

Co-packaged optics (CPO) technology can integrate photonic integrated circuits (PICs) with electronic integrated circuits (EICs) like CPUs and GPUs on a single platform. This advanced technology has ...

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 ...
