Film yo muri lithium niobate (ln) Photodetetector

Lithium Niobate (LN) ifite imiterere yihariye ya kirisiti yingaruka zidasanzwe, nkingaruka zidasanzwe, ingaruka za electro-optic, ingaruka za pyroelectric, hamwe ningaruka za piezoelectric. Muri icyo gihe, ifite ibyiza byo guhinduranya kwagurika idirishya rya sotratique no gutuza igihe kirekire. Ibi biranga kora ln urubuga rwingenzi kubisekuru bishya bya pushiness. Mubikoresho bya optique hamwe na sisitemu ya Optoelecronic, ibiranga LN birashobora gutanga imirimo ikungahaye n'imikorere, guteza imbere iterambere ryitumanaho ryiza, kubara neza, hamwe na optique yunvikana. Ariko, kubera kwinjiza intege nke hamwe nibiranga imitungo ya lithium, ishyirwa mubikorwa ryimiterere ya litbate iracyahuye nikibazo cyo kumenya ibintu bigoye. Mu myaka yashize, raporo muri uyu muriyi harimo ahanini ni ugufotora amafoto ya Waveguide hamwe na Photorojucccctor.
Amafoto ya Wavegue ashingiye kuri lithium niobate isanzwe yibanda ku itumanaho ryiza C-GAND (1525-1565NM). Kubijyanye n'imikorere, ln cyane cyane igira uruhare mu imiraba iyobowe, mugihe ibikorwa bya optoelectronique bishingiye cyane kuri silicon, iii-v itsinda rya bande ifungane, nibikoresho bibiri. Mubwubatsi nk'ubwubatsi, urumuri rwanduzwa na lithium niobate optique hamwe nigihombo gito, hanyuma gishora mubindi bikoresho bya pimiconductor bishingiye ku ngaruka za Phofeteric. Ibyiza ni ugukora umurongo muremure (~ ghz), voltage yo hasi, ingano ntoya, no guhuza na chip ya fotoki. Ariko, kubera gutandukanya imyanda ya methium niobate na semiconductor yibikoresho byayo, nubwo buri wese akora inshingano zabo, ln gusa akina uruhare mu kurwanya imiraba nindi mitungo myiza yamahanga ntabwo yakoreshejwe neza. Semiconductor ibikoresho bigira uruhare gusa muguhindura no kubura guhuza hamwe, bikaviramo itsinda rito ugereranije. Ukurikije ishyirwa mubikorwa ryihariye, guhuza urumuri uhereye kumucyo kuri lithium niobate optique wapguide bivamo igihombo gikomeye nibisabwa muburyo bukomeye. Byongeye kandi, imbaraga nyazo zumucyo zirashira kumuyoboro wa semiconductor ushinzwe ubusanzwe mukarere ka konti kamenyereye biragoye kuri olibrate, bigabanya imikorere yayo.
Gakondoamafotoikoreshwa mugushushanya porogaramu zisanzwe zishingiye kubikoresho bya semiconductor. Kubwibyo, kuri lithium niobate, igipimo cyoroheje cyoroheje kandi kibuza imitungo ituma idashyigikiwe nabashakashatsi batofotoye, ndetse ningingo igoye mumurima. Ariko, iterambere ryikoranabuhanga rya hetero kugutemanywa mumyaka yashize ryazanye ibyiringiro byubushakashatsi bwa litbate niobate ishingiye kubafotora. Ibindi bikoresho bifite urumuri rukomeye cyangwa kuba mu bubiko buhebuje burashobora guhuzwa na lithium niobate kugirango yishyure amakosa yayo. Muri icyo gihe, igihe gito gitera imiterere ya pyroelectric ya siyobate ya lithium kubera anotropi yacyo ishobora kugenzurwa no guhinduranya ibwAISI yamashanyarazi, bityo ihindura ibiranga Pyroelectric iranga ibitekerezo bya Optoelectronic. Iyi ngaruka yubushyuhe ifite ibyiza byo gutwara no kwitwara, kandi birashobora kuzuzwa kandi byahujwe nibindi bikoresho. Gukoresha Synchrous byingaruka zubushyuhe nifoto byafunguye ibihe bishya kuri lithium niobate ishingiye kubafotora, bigatuma ibikoresho byo guhuza ibyiza byingaruka zombi. No guhimba ibitagenda neza kandi ugere guhuza inyungu, ni hotspot yubushakashatsi mumyaka yashize. Byongeye kandi, imikoreshereze ya Ions Inglantation, Ubwubatsi bwa Band, hamwe na Snoreering Engineering nanone nanone nahisemo kandi gukemura ibibazo byo gutahura Litium niobate. Ariko, kubera ingorane ndende zo gutunganya Lithium, uyu murima uracyafite ibibazo bikomeye nko kwishyira hamwe, ibikoresho byamashusho na sisitemu, nibikorwa bidahagije, bifite agaciro gakomeye k'ubushakashatsi n'umwanya.

Igishushanyo 1, ukoresheje ingufu zidasanzwe muri ln bandgap nkuru nkurugohama Ugereranije na pyroelectric yabanjirije ln amafoto, mubisanzwe bigarukira kumuvuduko wa 100hz, iyiFotografiyaifite umuvuduko wihuse wo kugeza kuri 10khz. Hagati aho, muri uyu murimo, byerekanwe ko Magnesium ion akora ln irashobora kugera ku mpinduka zo hanze hamwe n'igisubizo kigera kuri 10khz. Uyu murimo uteza imbere ubushakashatsi ku mikorere yo hejuru kandiAmafoto Yihuta YihutaMububiko bwimikorere yose-chip ihuriweho na fone ya fotosic.
Muri make, urwego rw'ubushakashatsi rwafilm yo muri lithium niobateifite akamaro ka siyansi hamwe nubushobozi bukomeye bwo gusaba. Mugihe kizaza, hamwe niterambere ryikoranabuhanga no kwimbitse ubushakashatsi, film yo muri lithium niobate (ln) ifotoza izatera imbere yerekeza kwishyira hamwe. Guhuza uburyo butandukanye bwo kwishyira hamwe kugirango tugere ku mikorere yo hejuru, igisubizo cyihuse, hamwe na fagitire yoroheje fithium fithium niobate, izateza imbere cyane iterambere rya chip hamwe nubwenge bwubwenge, kandi butanga ibindi bishoboka kuri Igisekuru gishya cya Photonics Ponsics.
