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 ...

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 ...

NTT scientists in Japan have used a photonic crystal to slow 1550 nm light down to 1% of its normal speed. The researchers first fabricated a two-dimensional silicon photonic crystal slab using ...

These devices are the first to demonstrate simultaneous control of all four optical degrees of freedom, namely, amplitude, phase, polarization ellipticity, and polarization orientation--a world record ...
