De har en h\u00f6g skalbarhet och CMOS-kompatibilitet, men saknar en stark linj\u00e4r elektrooptisk effekt (Pockels) och lider av relativt h\u00f6g f\u00f6rlust och begr\u00e4nsad modulationslinj\u00e4ritet. F\u00f6r att komma till r\u00e4tta med dessa problem anv\u00e4nds tunnfilmsteknikerna LiNbO\u2083 och LiTaO\u2083 p\u00e5 SiPh-plattformar genom wafer bonding eller hybridintegration.<\/p>\n

Den anv\u00e4nds ofta i n\u00e4sta generations optiska sammankopplingar, koherenta kommunikationssystem och mikrov\u00e5gsfotonik.<\/p>\n
Litiumniobat i tunnfilm ger en stark Pockels-effekt, vilket m\u00f6jligg\u00f6r ultrasnabb optisk modulering med l\u00e5g ins\u00e4ttningsf\u00f6rlust. Det \u00e4r f\u00f6r n\u00e4rvarande industristandarden f\u00f6r optiska h\u00f6ghastighetsmodulatorer.<\/p>\n
Litiumtantalat i tunnfilm uppvisar liknande elektrooptiska egenskaper men har f\u00f6rb\u00e4ttrad termisk stabilitet, h\u00f6gre tr\u00f6skel f\u00f6r optiska skador och b\u00e4ttre enhetlighet p\u00e5 waferniv\u00e5. Det anses vara ett lovande alternativ f\u00f6r h\u00f6geffektiva och storskaliga applikationer.<\/p>\n
