Taxanaha Eo Modulator: Waa maxay sababta lithium niobate loogu yeedhay silikon indhaha

Lithium niobate waxaa sidoo kale loo yaqaan silikoon indhaha. Waxaa jirta odhaah ah "lithium niobate waa isgaadhsiinta indhaha waxa silikoon u yahay semiconductors." Muhiimadda Silicon ee kacaanka elektiroonigga ah, haddaba maxaa ka dhigaya warshadaha si rajo leh oo ku saabsan walxaha lithium niobate?

Lithium niobate (LiNbO3) waxaa loo yaqaan "silicon indhaha" warshadaha. Marka lagu daro faa'iidooyinka dabiiciga ah sida xasilloonida jireed iyo kiimikaad wanaagsan, daaqad indho-furan oo ballaadhan (0.4m ~ 5m), iyo isugeynta elektro-optical-ka weyn (33 = 27 pm/V), lithium niobate sidoo kale waa nooc crystal ah oo ceeriin badan leh. ilaha alaabta iyo qiimaha hoose. Waxaa si weyn loogu isticmaalaa filtarrada waxqabadka sare leh, aaladaha elektiroonigga ah, kaydinta holographic, bandhig holographic 3D, aaladaha indhaha ee aan tooska ahayn, isgaarsiinta quantum indhaha iyo wixii la mid ah. Dhanka isgaarsiinta indhaha, lithium niobate inta badan waxay ka ciyaartaa doorka wax-ka-beddelka iftiinka, waxayna noqotay wax soo saarka guud ee hadda jira-xawaaraha sare ee modulator-ka (electro-optical modulator)Eo Modulator) suuqa.

Waqtigan xaadirka ah, waxaa jira saddex tikniyoolajiyadeed oo waaweyn oo loogu talagalay is-beddelka iftiinka ee warshadaha: Modulator-ka elektiroonigga ah (Eo Modulator) oo ku saleysan iftiinka silicon, fosfide indium iyolithium niobatedhufto ee alaabta. Modulator Optical Modulator waxaa inta badan loo adeegsadaa modules-ka gudbinta isgaarsiineed ee xogta muddada-gaaban, modulator-ka indium phosphide modulator waxaa inta badan loo adeegsadaa aaladaha isgaarsiinta indhaha ee dhex-dhexaadka ah iyo kuwa fog, iyo modulator-ka elektiroonigga ah ee lithium niobate (Eo Modulator) ayaa inta badan loo adeegsadaa isgaadhsiinta isku xidhan ee shabakada laf dhabarta fog iyo hal-mawjadaha 100/200Gbps ee xarumaha xogta xawaaraha sare leh. Waxaa ka mid ah saddexda sare ee qalabka modulator-ka xawaaraha aadka u sarreeya, modulatorka filimka khafiifka ah ee lithium niobate modulator kaas oo soo baxay sannadihii u dambeeyay wuxuu leeyahay faa'iidada xawliga ah ee alaabta kale aysan la jaan qaadi karin.

Lithium niobate waa nooc ka mid ah walaxda aan noolaha ahayn, caanaha kiimikadaLiNbO3, waa crystal negative, ferroelectric crystal, polarized lithium niobate crystal leh piezoelectric, ferroelectric, photoelectric, optics aan online ahayn, heerkulbeegyada iyo sifooyinka kale ee alaabta, waqti isku mid ah oo leh saamaynta photorefractive. Lithium niobate crystal waa mid ka mid ah qalabka cusub ee loo isticmaalo inorganic, waa wax wanaagsan piezoelectric tamarta beddelka, wax ferroelectric, wax electro-optical, lithium niobate sida walxo electro-optical in isgaarsiinta indhaha ayaa door ku modulation iftiinka.

Maaddada lithium niobate, oo loo yaqaan "silikoon indhaha", waxay isticmaashaa nidaamkii ugu dambeeyay ee micro-nano si ay u nuujiso lakabka silicon dioxide (SiO2) ee lakabka silikon, ku xidho substrate lithium niobate heerkul sare si loo dhiso dusha sare ee dillaacsan, iyo ugu dambeyntii diirka ka baxsan filimka lithium niobate. Qalabka khafiifka ah ee la diyaariyey ee lithium niobate modulator wuxuu leeyahay faa'iidooyinka waxqabadka sare, qiimo jaban, cabbir yar, wax soo saar ballaaran, iyo waafaqsanaanta tignoolajiyada CMOS, waana xal tartan ah oo loogu talagalay isku xirka indhaha xawaaraha sare ee mustaqbalka.

Haddii xarunta kacaanka elektiroonigga ah lagu magacaabo maadada silikoon ee suurtagelisay, markaas kacaanka photonics waxaa laga yaabaa in lagu raad raaco walxaha lithium niobate, oo loo yaqaan "silicon optical" lithium niobate waa walax aan midab lahayn oo hufan oo isku dhafan saamaynta sawir-celinta, aan toos ahayn. saamaynta, saamaynta electro-optical, saamaynta acousto-optical, saamaynta piezoelectric iyo saamaynta kulaylka. Qaar badan oo ka mid ah hantideeda waxaa lagu xakameyn karaa halabuurka crystal, element doping, valence state control iyo arrimo kale. Waxaa si weyn loo isticmaalaa in lagu diyaariyo waveguide indhaha, beddelka indhaha, piezoelectric modulator,modulator-ka-elektarooniga ah, koronto-dhaliyaha labaad ee harmonic, badiyaha inta jeer ee laser iyo alaabooyin kale. Warshadaha isgaarsiinta indhaha, modulators ayaa ah suuq adeeg oo muhiim u ah lithium niobate.
