To improve the response, we virtually demonstrate novel LC switching between in-plane and out-of-plane for reversible switching between three orthogonal orientation states, broadening the range of continuous phase shifts. This LC switching is realized using a pair of substrates, each with two pairs of orthogonal finger-type electrodes and one grating-type electrode for in- and out-of-plane switching. An applied voltage generates an electric field that drives each switching process between the three distinct orientation states, enabling a rapid response.<\/p>\n<p><a href=\"https:\/\/opg.optica.org\/oe\/fulltext.cfm?uri=oe-31-5-8632\" target=\"_blank\" rel=\"noopener noreferrer\"><em>Optics Express<\/em> article<\/a><\/p>\n<figure><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.ee.nthu.edu.tw\/oh-e\/wp-content\/uploads\/2023\/02\/FoHighlight_HexaDirecSwitching_021623-scaled.jpg\" alt=\"\" width=\"2560\" height=\"1440\" class=\"aligncenter size-full wp-image-876\" \/><figcaption>(a) Layout of electrodes on each substrate in a periodic unit structure.
