Kuri Optoelectronics ya Silicon, Amafoto ya Silicon

AmafotoHindura ibimenyetso byumucyo mumashanyarazi, kandi nkuko amakuru yo kwimura amakuru akomeje kunoza, amafoto yihuta yihuta yinjijwe hamwe na platformy ya silicolectronics yahindutse urufunguzo rwibisekuru. Iyi ngingo izatanga incamake yamafoto yihuse-yihuta, ashimangira ubudage bushingiye kuri silicon (ge cyangwa si Photodetetector)Amafoto ya Siliconkuri tekinoroji ya OPTONELTMOTROLTICSITIKI.

Ikidage ni ibintu byiza cyane ku buryo bworoshye bwo kumenya uburabyo ku rubuga rwa silicon kuko bihuye na CMO inzira kandi bikaba bikurura cyane kuri telesoluteng uburebure. Imiterere isanzwe ya ge / SI ni diode ya pin, aho gechurique yimbere yashizwe hagati yubwoko bwa p-ubwoko nubundi.

Imiterere yibikoresho 1 yerekana iginini gisanzwe cya Vertical GRA cyangwaSI PhotodetectorImiterere:

Ibiranga nyamukuru birimo: Ubudage gukuramo igice cyakuze kuri silicon sustrate; Ikoreshwa mu gukusanya p na N contacts zishinzwe abatwara intwara; Guhuza guhuza kugirango binjire neza.

Gukura Kwiyongera: Gukura ubuziranenge bwubudage kuri silicon biragoye bitewe na 4.2% Lattice idahuye hagati yibikoresho byombi. Iterambere ryintambwe ebyiri zikoreshwa: Ubushyuhe buke (300-400 ° C) Buffer Igice cyo Gukura no Kurenza Ubushyuhe (Hejuru ya 600 ° C) Kubitsa Ubudage. Ubu buryo bufasha kugenzura imitwe yatewe na Latsice Mismatches. Nyuma yo gukura kuri 800-900 ° c kure zigabanya ubucucike bwa charlocation kuri 10 ^ 7 ^ -2. Ibiranga imikorere: Ifoto ya Enter Imbere cyane irashobora kugeraho: Kwitabira,> 0.8A / W saa 1550 nm; Umurongo,> 60 ghz; Ubu bwicukuzi bwijimye, <1 μI kuri -1 v kubogama.

Kwishyira hamwe hamwe na status ya silicon

Kwishyira hamwe kwaAmafoto YihutaHamwe na platike ishingiye kuri silicon-ishingiye kuri platforms ifasha abasekuruza bakuru hamwe nimikoranire. Uburyo bubiri bwingenzi bwo kwishyira hamwe ni ibi bikurikira: Kwishyira hamwe byimbere (Feol), aho pakedetector na trapiskor icyarimwe bakorewe kumurongo wa silicon wemerera gutunganya ubushyuhe bwinshi, ariko bafata akarere ka chip. Kwishyira hamwe-kurangiza (beol). Amafoto yakozwe hejuru yicyuma kugirango wirinde kwivanga na CMO, ariko bigarukira kubushyuhe butunganijwe.

Igishushanyo 2: Kwitabira hamwe na Bandidth yumuvuduko mwinshi ge / SI Photodetetector

Gusaba amakuru

Amafoto yihuta yihuta nikintu cyingenzi mubisekuru bizakurikiraho byimikorere ya Data. Porogaramu nyamukuru zirimo: Infezizi nziza: 100g, 400g n'igiciro cyo hejuru, ukoresheje pam-4 modulation; AAmafoto Yinyuma ya Bandwidth(> 50 ghz) birakenewe.

Optoelectronic ya Silicon ishingiye ku muzunguruko: Kwinjiza monolic yo guterwa na modulator nibindi bice; Moteri yoroshye, yimikorere miremire.

Ubwubatsi: Guhuza neza hagati yo kubara, kubika, no kubika; Gutwara ibisabwa byingufu-ikora neza, amafoto menshi-abunga.

Ibizaza

Ejo hazaza h'amafoto yihuta yihuta-abafotore bizerekana inzira zikurikira:

Igipimo cyamakuru arenze: Gutwara iterambere rya 800g na 1.6t abasekuruza; Amafoto hamwe na bandidths arenga 100 ghz.

Kwishyira hamwe: guhuza chip imwe ya bii-v ibikoresho na silicon; Tekinoroji yagezweho ya 3D.

Ibikoresho bishya: Gushakisha ibikoresho bibiri-binini (nka graphene) kugirango uburanirwe; Itsinda rishya IV ALLY yo kwagura uburebure bwa garele.

Porogaramu igaragara: Lidar nibindi bikoresho byo kumva bitwara iterambere rya APD; Microwave Phoon isaba amasaha menshi.

Amafoto yihuta yihuta, cyane cyane ge cyangwa amafoto, yabaye umushoferi wingenzi wa silicolectronika ya silicon-selicolectronics hamwe nitumanaho ryiza. Gukomeza gutera imbere mubikoresho, igishushanyo cyibikoresho, hamwe nikoranabuhanga ryihuza ni ngombwa kugirango duhuze ibisabwa bikura ibigo bizaza hamwe n'imiyoboro y'itumanaho. Mugihe umurima ukomeje guhinduka, turashobora kwitega kubona abafototeri bafite umurongo mwinshi, urusaku rwinshi, hamwe no kwishyira hamwe kwagaciro hamwe na elegisi ya elegitori na photonic na photonic.
