Efficient free-space optical switching harnessing quasi-guided modes in a corrugated lithium niobate grating

We report and demonstrate an efficient free-space optical switching scheme by harnessing the high-Q resonances of quasi-guided modes (QGMs) supported by a corrugated Lithium Niobate grating on a slab waveguide. The well-confined guided modes in the slab are inaccessible by free-space radiations, so...
