data-start=\"688\" data-end=\"830\">The structure consists of a single-crystal lithium niobate thin film bonded onto a SiO\u2082 insulating layer and supported by a silicon substrate.<\/p>\n<p data-start=\"832\" data-end=\"1001\">This configuration provides strong optical confinement, ultra-low propagation loss, and high electro-optic efficiency, making it a key platform for integrated

data-start=\"1052\" data-end=\"1197\">Thin-Film Lithium Niobate (TFLN) refers to a sub-micron crystalline LiNbO\u2083 layer engineered for optical waveguide and electro-optic applications.<\/p>\n<p data-start=\"1199\" data-end=\"1334\">Compared with bulk lithium niobate, TFLN enables tighter optical confinement, smaller device footprint, and higher integration density.<\/p>\n<p data-start=\"1336\" data-end=\"1429\">TFLN is typically implemented on LNOI wafers to form a complete integrated photonic platform.<\/p>\n<hr data-start=\"1431\" data-end=\"1434\" \/>\n<h1
