New York, NY—May 8, 2023—Researchers at Columbia Engineering have developed a new class of integrated photonic devices--“leaky-wave metasurfaces”--that can convert light initially confined in an ...

Optical solitons represent a unique phenomenon in nonlinear optics whereby light waves maintain their integrity over long distances by balancing dispersion with nonlinear effects. When these solitons ...

Researchers have now achieved high-Q photonic flatbands that span the entire k-space of nonlocal metasurfaces and can be selectively tailored for linearly polarized or circularly polarized light, ...

Waveguides are structures designed to direct and control the propagation of electromagnetic waves from one point to another. They play a crucial role in various fields, including telecommunications, ...

Vuzix, the US-based producer of augmented reality (AR) smart glasses, says that its new optical waveguide manufacturing facility is up and running, with devices now being sampled. Located adjacent to ...
