Ihame no kwerekana ukoAvalanche Photodetetector (APD Photodetetector) Igice cya kabiri

2.2 INGINGO CHD
Imiterere ifatika ni garanti yibanze yibikoresho byimbitse. Igishushanyo mbonera cya APD gisuzuma ahanini rc igihe gihoraho, umwobo ufata kuri hetero kugutection, igihe cya kabiri cyitwara binyuze mukarere kangiritse nibindi. Iterambere ryurwego ryayo rivuga muri make hepfo:

(1) Imiterere y'ibanze
Imiterere yoroshye ya APD ishingiye kuri Pin Photodiode, akarere ka P na Nkarere kabigizemo uruhare cyane, kandi ubwoko bwa n-ubwoko bwa n-nyabwo, kugirango tumenye ko byarose bya electrodiary. Kuri Inoces Ibikoresho bya Inos, kubera ko umwobo ufite ingaruka muri ioniation coefficient aruta impengamiro ya electron, urwego rwakarere rwa n-ubwoko rusanzwe rushyirwa mukarere. Mubihe byiza, gusa ibyobo byatewe mukarere, niko iyi miterere yitwa imiterere yashizwemo.

(2) kwinjiza kandi inyungu zitandukanijwe
Bitewe n'itsinda ryagutse ryibiranga inp (inp ni 1.35ev na Ingaas ni 0.75Ev), IDP isanzwe ikoreshwa nkibikoresho bya zone na kato.

(3) kwinjiza, gradient ninyungu (sage) nibisabwa
Kugeza ubu, ibikoresho byinshi bya APD bakoresha ibikoresho bya IDP / Ingaas, ishami ikurura urwego, umurongo wo mu mashanyarazi. Kuri ibi bikoresho, igishushanyo cyiyi APD nuko inzira ya Avalanche ikorwa muri N-Ubwoko bwa ITP kugongana. Urebye itandukaniro rinini mu cyuho kiri hagati ya IDP na Ingaas, itandukaniro ry'ingufu rishingiye ku mukino wa Ingaation ryinjira mu ntera ya Ingaation mbere yo kugera ku nkombe za Ingaation zirimo kuzenguruka. Iki kibazo kirashobora gukemurwa wongeyeho urwego rwinzibacyuho hagati yibikoresho byombi.

(4) kwinjiza, Gradient, kwishyuza no kunguka (SAGCM) imiterere irasabwa
Kugirango uhindure uburyo bwo gukwirakwiza amashanyarazi akuramo urwego rwinshi hamwe nunguka urwego, urwego rwishyurwa rwitangizwa mubishushanyo, bikaba byateje imbere cyane ibikoresho byigikoresho no kugaza.

(5) Resonator yazamuye (RCE) imiterere ya sagcm
Mubishushanyo mbonera byateganijwe byatanzwe nibice gakondo, tugomba guhangana nuko umubumba ukurura urwego rwihuta nigikoresho kivuguruzanya kubikoresho byihuta nibikoresho. Ubunini bworoshye bwurwego rukurura rushobora kugabanya igihe cyitwara, bityo umurongo munini wagabatswe. Ariko, icyarimwe, kugirango ubone imikorere yo hejuru, urwego rushingiye rukeneye kugira ubunini buhagije. Igisubizo cyiki kibazo gishobora kuba umwobo uhumeka (RCE), ni ukuvuga kuringaniza bragg yerekana (DBR) yateguwe hepfo no hejuru yigikoresho. Indorerwamo ya DBR igizwe nuburyo bubiri bwibikoresho bivuguruzanya hamwe nuburyo buke bwo kumvikana hamwe nuburyo bworoshye bworoshye, kandi byombi bikura ubundi, kandi ubunini bwa buri gice cyujuje ibyabaye 1/4 muri Semiconductor. Imiterere ya Renator ya Deteri irashobora kuzuza ibisabwa byihuta, ubunini bwo kwinjiza urwego burashobora gukorwa cyane, kandi imikorere ya electrod yiyongereye nyuma yibitekerezo byinshi.

(6) inkombe-coupd waveguide (wg-apd)
Ikindi gisubizo cyo gukemura ibibazo bitandukanye byingirakamaro mubyifuzo byumubiri wihuta kubikoresho hamwe no kumenyekanisha imikorere yihuta na oubled ya Waveguide. Iyi nyubako ihuza urumuri kuva kuruhande, kubera ko ingenzi cyane ari ndende cyane, biroroshye kubona imikorere miremire, kandi icyarimwe, urwego rutoroshye rushobora gukorwa cyane, kugabanya igihe cyitwara. Kubwibyo, iyi nyubako ikemura aho ihuriweho n'umurongo unyuranye no gukora neza ku bunini bw'ikirere ikurura, kandi biteganijwe ko bizagera ku gipimo kinini kandi gifite umusaruro mwinshi. Inzira ya WG-APD ntabwo yoroshye kuruta izo rce apd, ikuraho inzira igoye yimyiteguro yindorerwamo ya DBR. Kubwibyo, birashoboka cyane mubikorwa bifatika kandi bikwiranye nindege isanzwe ihuza.

3. UMWANZURO
Iterambere rya AvalanchePhotodetetectorIbikoresho n'ibikoresho birasubirwamo. Electron na Hole Ibiciro bya Ioniation yibikoresho bya INP biri hafi yibyo INALAS, biganisha kumikorere ibiri ya symbike ebyiri, ituma igihe cyo kubaka inzara, urusaku rwiyongera. Ugereranije nibikoresho byiza bya inalas, Ingaas (P) / Inala kandi muri (Al) Gaas / Inalas Quas Kubijyanye n'imiterere, regonator yazamuye (RCE) imiterere ya Sagcm hamwe na coupled ya Waveguide (WG-APD) yatejwe no gukemura amakosa ku ngaruka zinyuranye zo kwinjiza igice cyimigenzo hamwe na quanim. Bitewe nuburyo bugoye, gushyira mubikorwa byuzuye byizi nzego zombi bigomba gukomeza gukomeza ubushakashatsi.
