"Since hBN is used so widely in 2D material–based devices, this novel usage as an optical waveguide potentially has wide-ranging impacts." Graphene and TMD monolayers are both extremely sensitive to ...

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 ...

A powerful new microscopy technique unveils hidden nanoscale light interactions, offering a glimpse into physics that ...

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, ...

Comprised of judiciously engineered microscopic photonic structures with subwavelength features, the concept of metasurface and metamaterials have proven fruitful results in the realm of meta-optics.

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...

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 ...

What are modal effects? Integrated photonics—the devices and the materials used to make them happen. One of the key planar-waveguide configurations: the ring resonator. The roots of waveguide optics ...

Augmented reality (AR) technology developer Magic Leap has signed an agreement with the Taiwan-based electronics manufacturer Pegatron, in a move that should see the latter ramp production of optical ...
