Lithium niobate waxaa sidoo kale loo yaqaan silicon optical. Waxaa jira maahmaah oranaysa "lithium niobate waa isgaarsiinta indhaha waxa silikoonku u yahay semiconductors." Muhiimadda silikoonku u leeyahay kacaanka elektaroonigga ah, markaa maxaa ka dhigaya warshadaha kuwo aad u rajo wanaagsan oo ku saabsan walxaha lithium niobate?
Lithium niobate (LiNbO3) waxaa loo yaqaan "silikoni indhaha" warshadaha. Marka laga soo tago faa'iidooyinka dabiiciga ah sida xasilloonida jireed iyo kiimikada wanaagsan, daaqadda iftiinka ballaaran (0.4m ~ 5m), iyo isku-dhafka weyn ee electro-optical (33 = 27 pm/V), lithium niobate sidoo kale waa nooc ka mid ah kiristaalka oo leh ilo badan oo ceeriin ah iyo qiimo jaban. Waxaa si weyn loogu isticmaalaa shaandheeyayaasha waxqabadka sare leh, aaladaha electro-optical, kaydinta holographic, bandhigga holographic 3D, aaladaha indhaha ee aan tooska ahayn, isgaarsiinta quantum indhaha iyo wixii la mid ah. Dhanka isgaarsiinta indhaha, lithium niobate waxay inta badan ciyaartaa doorka wax-ka-beddelka iftiinka, waxayna noqotay badeecada ugu weyn ee modulator-ka electro-optical-ka ee hadda jira (Eo Modulator) suuq.
Waqtigan xaadirka ah, waxaa jira saddex teknoolojiyad oo muhiim ah oo loogu talagalay wax ka beddelka iftiinka warshadaha: modulators electro-optical (Eo Modulator) oo ku salaysan iftiinka silicon, indium phosphide iyolithium niobateMadal agab. Qalabka elektaroonigga ah ee Silicon waxaa inta badan loo isticmaalaa qaybaha gudbinta xogta ee heerka gaaban, qalabka elektaroonigga ah ee indium phosphide waxaa inta badan loo isticmaalaa qaybaha gudbinta shabakadda isgaarsiinta indhaha ee heerka dhexe iyo heerka fog, iyo qalabka elektaroonigga ah ee lithium niobate (Eo Modulator) waxaa inta badan loo isticmaalaa isgaarsiinta isku xiran ee shabakadda laf-dhabarta ee heerka fog iyo xarumaha xogta ee xawaaraha sare ee hal-hirarka 100/200Gbps. Saddexda goobood ee qalabka modulator-ka xawaaraha sare ee sare ee kor ku xusan, qalabka elektaroonigga ah ee lithium niobate ee khafiifka ah ee soo baxay sannadihii la soo dhaafay wuxuu leeyahay faa'iidada bandwidth-ka ee agabka kale aysan la jaan qaadi karin.
Lithium niobate waa nooc ka mid ah walax aan dabiici ahayn, qaacido kiimiko ahLiNbO3, waa kiristaalo taban, kiristaalo ferroelectric ah, kiristaalo lithium niobate ah oo polarized ah oo leh piezoelectric, ferroelectric, photoelectric, optics nonlinear, thermoelectric iyo sifooyin kale oo walxaha ah, isla markaana leh saameyn photorefractive ah. Kiristaalo Lithium niobate waa mid ka mid ah agabyada cusub ee aan organic ahayn ee ugu isticmaalka badan, waa walax isdhaafsi tamar oo piezoelectric ah oo wanaagsan, walax ferroelectric ah, walax electro-optical ah, lithium niobate oo ah walax electro-optical ah oo ku jirta isgaarsiinta indhaha ayaa door ka ciyaara isbeddelka iftiinka.
Walxaha lithium niobate, oo loo yaqaan "silicon indhaha", waxay isticmaalaan habka ugu dambeeyay ee micro-nano si ay u uumiiyaan lakabka silicon dioxide (SiO2) ee substrate-ka silicon, waxay ku xidhaan substrate-ka lithium niobate heerkulka sare si ay u dhisaan dusha sare ee kala-goynta, ugu dambayntiina waxay ka saaraan filimka lithium niobate. Qalabka lithium niobate ee khafiifka ah ee la diyaariyey wuxuu leeyahay faa'iidooyinka waxqabadka sare, qiimaha hooseeya, cabbirka yar, wax soo saarka tirada badan, iyo iswaafajinta tiknoolajiyada CMOS, waana xal tartan ah oo loogu talagalay isku-xirka indhaha ee xawaaraha sare leh mustaqbalka.
Haddii xarunta kacaanka elektaroonigga loogu magac daro walaxda silicon ee suurtogalisay, markaa kacaanka photonics waxaa laga yaabaa in lagu raad raaco walaxda lithium niobate, oo loo yaqaan "silicon indhaha" lithium niobate waa walax aan midab lahayn oo isku daraysa saamaynta sawir-qaadista, saamaynta aan tooska ahayn, saamaynta elektaroonigga ah, saamaynta acousto-optical, saamaynta piezoelectric iyo saamaynta kulaylka. Qaar badan oo ka mid ah sifooyinkeeda waxaa xakamayn kara halabuurka kiristaalka, doping curiyaha, xakamaynta xaaladda valence iyo arrimo kale. Waxaa si weyn loogu isticmaalaa diyaarinta hagaha hirarka indhaha, badhanka indhaha, modulator-ka piezoelectric,modulator-ka elektaroonigga ah, matoorka labaad ee harmonic, isku-darka soo noqnoqda ee laysarka iyo alaabooyin kale. Warshadaha isgaarsiinta indhaha, modulators-ku waa suuq codsi oo muhiim u ah lithium niobate.
