I-lithium niobate electro-optical phase modulator(i-lithium niobate modulator) esekelwe kunqubo yokusabalalisa i-titanium inezici zokulahlekelwa ukufakwa okuphansi, umkhawulokudonsa ophezulu wokuguquguquka, umkhawulo ophansi wamagagasi kagesi, umonakalo omkhulu wamandla okubona, njll. Isetshenziswa kakhulu emkhakheni we-optical ukulawulwa kwe-chirp ezinhlelweni zokuxhumana ze-high-speed optical, ukushintshwa kwesigaba ezinhlelweni zokuxhumana ezihambisanayo, ukukhiqizwa kwamabhande aseceleni ezinhlelweni ze-ROF, kanye nokunciphisa ukuhlakazeka kwe-Brillouin (SBS) okuvuselelwe ezinhlelweni zokuxhumana ze-analog optical fiber.
