Adaptive optics (AO) systems play a pivotal role in mitigating the deleterious effects of atmospheric turbulence and optical aberrations, thereby enhancing the resolution and imaging quality in fields ...

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 ...

Researchers at Columbia Engineering have developed a new class of integrated photonic devices—"leaky-wave metasurfaces"—that can convert light initially confined in an optical waveguide to an ...
