The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State University, has discovered slab waveguides based on the two-dimensional material hexagonal boron nitride. This milestone ...

Real-space (left) and Fourier space (right) photoluminescence image of a hexagonal boron nitride waveguide. The real-space image shows where photoluminescence is emitted from within the sample, while ...

In this paper, a general method for analyzing arbitrary planar negative-refractive-index (NRI) multilayer slab optical waveguide structures was proposed. Some degenerated examples were introduced to ...

This paper presents a novel silicon-based metasurface-coated one-dimensional (1D) slab waveguide. The proposed idea can easily engineer and mold guided waves into any desired free-space mode and ...

The US Naval Research Laboratory (NRL), in partnership with Kansas State University, reported the development of slab waveguides made of the two-dimensional material hexagonal boron nitride. This ...

The report "Optical Waveguide Market by Type (Planar, Channel), Material (Glass, Polymer, Semiconductor), Propagation (Single-mode, Multi-mode), Refractive Index (Step-index, Graded-index), ...

Holographic images: the two figures on the left are two holographic images produced by a leaky-wave metasurface at two different distances from the device surface. The other figures are distinct ...

A simple, solid-state waveguide that can “stop” light has been proposed by physicists in the UK. The researchers say that their device – which has yet to be built in the lab – would be straightforward ...
