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 ...
The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles.
(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 ...
