Tun daga farkon masana'antar har zuwa yanzu, ƙarfin sadarwa ta fiber guda ɗaya ya ƙaru da miliyoyin sau, kuma ƙaramin adadin bincike na zamani ya wuce sau dubun-dubatar miliyoyin. Lithium niobate ya taka rawa sosai a tsakiyar masana'antarmu. A farkon zamanin sadarwa ta fiber optical, ana daidaita siginar gani kai tsaye akan na'urorin hangen nesa.laserWannan hanyar daidaitawa abu ne mai karɓuwa a aikace-aikacen ƙarancin bandwidth ko gajere. Don aikace-aikacen daidaitawa mai sauri da aikace-aikacen nisa mai nisa, ba za a sami isasshen bandwidth ba kuma tashar watsawa tana da tsada sosai don biyan buƙatun nesa mai nisa.
A tsakiyar sadarwa ta fiber optic, tsarin siginar yana da sauri da sauri don biyan karuwar ƙarfin sadarwa, kuma yanayin daidaita siginar optic yana fara rabuwa, kuma ana amfani da hanyoyi daban-daban na daidaitawa a cikin hanyar sadarwa ta gajere da hanyar sadarwa ta dogon lokaci. Ana amfani da tsarin daidaitawa kai tsaye mai rahusa a cikin hanyar sadarwa ta gajere, kuma ana amfani da wani "mai daidaita lantarki" daban a cikin hanyar sadarwa ta dogon lokaci, wanda aka raba shi da laser.
Mai daidaita wutar lantarki yana amfani da tsarin tsangwama na Machzender don daidaita sigina, haske shine raƙuman lantarki, tsangwama na raƙuman lantarki yana buƙatar mitar sarrafawa mai ƙarfi, lokaci da kuma rarrabuwar kawuna. Sau da yawa muna ambaton kalma, da ake kira rassan tsangwama, haske da rassan duhu, mai haske shine yankin da tsangwama na lantarki ke ƙaruwa, duhu shine yankin da tsangwama na lantarki ke haifar da rauni ga makamashi. Tsangwama na Mahzender wani nau'in interferometer ne mai tsari na musamman, wanda shine tasirin tsangwama da ake sarrafawa ta hanyar sarrafa matakin hasken guda bayan raba hasken. A wata ma'anar, ana iya sarrafa sakamakon tsangwama ta hanyar sarrafa matakin tsangwama.
Ana amfani da Lithium niobate wannan kayan a cikin sadarwa ta fiber optic, wato, yana iya amfani da matakin ƙarfin lantarki (siginar lantarki) don sarrafa matakin haske, don cimma daidaiton siginar haske, wanda shine alaƙar da ke tsakanin mai daidaita haske na lantarki da lithium niobate. Ana kiran mai daidaita haskenmu mai daidaita haske na lantarki, wanda ke buƙatar la'akari da daidaiton siginar lantarki da ingancin daidaitawar siginar gani. Ƙarfin siginar lantarki na indium phosphide da silicon photonics ya fi na lithium niobate kyau, kuma ƙarfin siginar gani yana da ɗan rauni amma ana iya amfani da shi, wanda ke ƙirƙirar sabuwar hanya don amfani da damar kasuwa.
Baya ga kyawawan halayen wutar lantarki, indium phosphide da silicon photonics suna da fa'idodin miniaturization da haɗin kai wanda lithium niobate ba shi da shi. Indium phosphide ya fi lithium niobate ƙanƙanta kuma yana da babban matakin haɗin kai, kuma silicon photons sun fi indium phosphide ƙanƙanta kuma suna da babban matakin haɗin kai. Kan lithium niobate a matsayinmai daidaitatsawonsa ya ninka na indium phosphide sau biyu, kuma zai iya zama mai daidaita abubuwa ne kawai kuma ba zai iya haɗa wasu ayyuka ba.
A halin yanzu, na'urar sarrafa hasken lantarki ta shiga zamanin ƙimar alamar biliyan 100, (128G shine biliyan 128), kuma lithium niobate ta sake yin fafutukar shiga gasar, kuma tana fatan jagorantar wannan zamanin nan gaba kaɗan, tana jagorantar shiga kasuwar ƙimar alamar biliyan 250. Domin lithium niobate ta sake kwace wannan kasuwa, ya zama dole a yi nazarin abin da indium phosphide da silicon photons suke da shi, amma lithium niobate ba shi da shi. Wannan ƙarfin lantarki ne, haɗin kai mai girma, da kuma ƙaramin aiki.
Canjin lithium niobate yana cikin kusurwoyi uku, Kusurwoyi na farko shine yadda ake inganta ƙarfin lantarki, Kusurwoyi na biyu shine yadda ake inganta haɗin kai, Kusurwoyi na uku kuma shine yadda ake rage girmansa. Mafita ga waɗannan kusurwoyi uku na fasaha yana buƙatar aiki ɗaya kawai, wato, a rage girman kayan lithium niobate, a cire wani siririn Layer na kayan lithium niobate a matsayin jagorar hasken gani, za ku iya sake tsara electrode, a inganta ƙarfin lantarki, a inganta bandwidth da ingancin daidaitawa na siginar lantarki. Inganta ƙarfin lantarki. Wannan fim ɗin kuma ana iya haɗa shi da wafer silicon, don cimma haɗin kai gauraye, lithium niobate a matsayin mai daidaita sauti, sauran haɗin silicon photon, ikon rage girman silicon photon a bayyane yake ga kowa, fim ɗin lithium niobate da haɗin haɗin silicon haske, a inganta haɗin kai, a cimma ƙaramin haske ta halitta.
Nan gaba kadan, na'urar sarrafa hasken lantarki (electro-optical modulator) za ta shiga zamanin darajar alamar biliyan 200, rashin kyawun gani na indium phosphide da silicon photons yana kara bayyana, kuma fa'idar gani na lithium niobate tana kara bayyana, kuma fim din lithium niobate na kara inganta rashin kyawun wannan kayan a matsayin mai daidaita haske, kuma masana'antar ta mai da hankali kan wannan "siraran fim na lithium niobate", wato, fim din siriri.na'urar daidaita lithium niobateWannan shine rawar da sinadarin lithium niobate mai siriri ke takawa a fannin na'urorin daidaita hasken lantarki.
