Over the past decade, metasurfaces deploying two-dimensional artificial nanostructures have emerged as a groundbreaking platform to manipulate light across various degrees of freedom. These ...

(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 in Caltech's Andrew and Peggy Cherng Department of Medical Engineering have made what they call "a major step forward in medical imaging" by taking inspiration from the field of astronomy.

Lithium niobate (LN) powers a newly developed optical metasurface for shaping and guiding light waves. Leveraging the electro-optical effect of lithium niobate, the device applies different electric ...
