Ana kuma kiran Lithium niobate da silikon gani. Akwai wata karin magana da ke cewa "lithium niobate ga sadarwa ta gani kamar yadda silikon yake ga semiconductors." Muhimmancin silikon a juyin juya halin lantarki, to me ya sa masana'antar ke da kyakkyawan fata game da kayan lithium niobate?
An san Lithium niobate (LiNbO3) da "silikon gani" a masana'antar. Baya ga fa'idodin halitta kamar kyakkyawan kwanciyar hankali na jiki da sinadarai, taga mai faɗi mai haske (0.4m ~ 5m), da babban ma'aunin electro-optical (33 = 27 pm/V), lithium niobate shima wani nau'in lu'ulu'u ne mai wadataccen tushen kayan masarufi da ƙarancin farashi. Ana amfani da shi sosai a cikin matatun mai aiki mai yawa, na'urorin electro-optical, ajiyar holographic, nunin holographic na 3D, na'urorin gani marasa layi, sadarwa ta quantum da sauransu. A fannin sadarwa ta gani, lithium niobate galibi yana taka rawar daidaita haske, kuma ya zama babban samfuri a cikin mai amfani da na'urar lantarki mai saurin gudu (Eo Modulator) kasuwa.
A halin yanzu, akwai manyan fasahohi guda uku don daidaita haske a masana'antar: masu daidaita haske na lantarki (Eo Modulator) bisa hasken silicon, indium phosphide dalithium niobatedandamalin kayan aiki. Ana amfani da na'urar silicon optical modulator galibi a cikin na'urorin transceiver na sadarwa na bayanai na ɗan gajeren zango, indium phosphide modulator galibi ana amfani da shi a cikin na'urorin transceiver na sadarwa na gani na matsakaici da dogon zango, kuma lithium niobate electro-optical modulator (Eo Modulator) galibi ana amfani da shi a cikin hanyoyin sadarwa masu haɗin gwiwa na dogon zango da cibiyoyin bayanai masu saurin gaske na 100/200Gbps guda ɗaya. Daga cikin dandamali uku na kayan modulator na sauri mai sauri, siraran fim na lithium niobate modulator wanda ya fito a cikin 'yan shekarun nan yana da fa'idar bandwidth da sauran kayan ba za su iya daidaitawa ba.
Lithium niobate wani nau'in abu ne mai rashin tsari, dabarar sinadaraiLiNbO3, lu'ulu'u ne mai kama da lu'ulu'u ...
Kayan lithium niobate, wanda aka sani da "silicon na gani", yana amfani da sabon tsarin micro-nano don tururi layin silicon dioxide (SiO2) akan substrate na silicon, haɗa substrate na lithium niobate a zafin jiki mai yawa don gina saman raba, sannan a ƙarshe ya cire fim ɗin lithium niobate. Siririn fim ɗin lithium niobate modulator da aka shirya yana da fa'idodin babban aiki, ƙarancin farashi, ƙaramin girma, yawan samarwa, da kuma dacewa da fasahar CMOS, kuma mafita ce mai gasa don haɗin kai mai sauri a nan gaba.
Idan aka sanya wa tsakiyar juyin juya halin lantarki suna bayan kayan silicon da suka sa ya yiwu, to juyin juya halin photonics zai iya komawa ga kayan lithium niobate, wanda aka sani da "silicon na gani" lithium niobate abu ne mai haske mara launi wanda ya haɗu da tasirin photorefractive, tasirin da ba na layi ba, tasirin electro-optical, tasirin acousto-optical, tasirin piezoelectric da tasirin zafi. Yawancin kaddarorinsa ana iya sarrafa su ta hanyar abubuwan da ke cikin lu'ulu'u, abubuwan da ke cikin sinadarai, sarrafa yanayin valence da sauran abubuwa. Ana amfani da shi sosai don shirya jagorar waveleptic, maɓallin gani, mai daidaita piezoelectric,na'urar sarrafa haske ta lantarki (electro-optical modulator), janareta na biyu mai haɗakar sauti, mai ninka mitar laser da sauran kayayyaki. A cikin masana'antar sadarwa ta gani, masu daidaita sauti muhimmin kasuwa ne na aikace-aikacen lithium niobate.
