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, ...
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 ...
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 ...
