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 ...

The first theoretical models of the propagation of an electromagnetic field in a waveguide date back to the second half of the 19th century (Hertz, Debye, Rayleigh). The technological fallout for long ...

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 waveguide to an ...

Specifics of non-electronic issues with waveguides. How nylon can be used to make waveguides via additive manufacturing. The virtues of a unique coating that metallizes the nylon waveguide for use.

Since its inception, augmented reality (AR) technology has faced a persistent engineering challenge: achieving a wide field of view (FOV) and excellent display quality within a compact and lightweight ...
