A technical paper titled “Unlocking the monolithic integration scenario: optical coupling between GaSb diode lasers epitaxially grown on patterned Si substrates and passive SiN waveguides” was ...

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 ...

Throughout the evolution of AR technology, display systems have consistently aimed for a balance between clarity and compactness. Diffractive waveguides, known for their slim profiles, have become ...

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 ...

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 ...
