Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in ...

(a) Schematic illustration of the proposed signal modulation process. Left: initial input laser spot illustration before interacting with the SLM and Si metasurface. Middle: schematic of the linear ...

Researchers have devised a novel technique to 'flip' the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion ...

Researchers at Caltech make progress in medical imaging by adapting astronomical optics. A reflector shapes light waves to counterbalance distortion. Researchers in Caltech’s Andrew and Peggy Cherng ...

Researchers at the University of California, Los Angeles (UCLA) have developed an optical computing framework that performs large-scale nonlinear computations using linear materials. Subscribe to our ...

A new technical paper titled “Massively parallel and universal approximation of nonlinear functions using diffractive processors” was published by researchers at UCLA. “Nonlinear computation is ...

Aspheric lenses are designed to focus or collimate light without introducing spherical aberration into the transmitted wavefront. For monochromatic sources, spherical aberration is often what prevents ...
