Kwa a Silicon-zochokera ku Silicon, Silicn Photooders

Ojambula zithunziSinthani mawonekedwe owala kukhala magetsi Nkhaniyi ifotokoza mwachidule zithunzi zapamwamba kwambiri za maluwa othamanga kwambiri, motsimikiza pa silika yochokera ku Germanium (ge kapena s Photodtector)Silicon Photodetorspophatikizira ukadaulo wa octuectonics.

Germanium ndi zinthu zokongola pafupi ndi zowunikira zopepuka za silika chifukwa zimagwirizana ndi njira za CMOS ndipo zimayamwa kwambiri mayamwidwe. Kapangidwe kakang'ono kwambiri kwa ge / sidedcy ndi ma pini daide, komwe ku Germanium Germanium imasungidwa pakati pa zigawo za P-mtundu ndi n-mtundu.

Chipangizo cha Chipangizo cha Chipangizo 1 chikuwonetsa chopindika chokhazikikaSI PhotodtectorKapangidwe:

Zoterezi zimaphatikizapo: Germanium yotenga shirse yolimidwa pa silikan gawo; Ankakonda kutolera p ndi nkumanani kwa onyamula; Kuphatikizira kulumikizana kwa kuyamwa koyenera.

Kukula kwa Epithexial: Kukula ku Germanium yapamwamba kwambiri pa silika ndikovuta chifukwa cha vuto la 4.2% la Lattice pakati pa zinthu ziwirizi. Kukula kwa magawo awiri kumagwiritsidwa ntchito: kutentha kochepa (300-400 ° C) Kutentha kwambiri (pamwamba pa 600 ° C) Kupanga Germanium. Njirayi imathandizira kuwongolera dislocation yolumikizidwa yoyambitsidwa ndi malata. Kukula kwa post pa 800-900 ° Ch kumachepetsa kachulukidwe katatu mpaka 10 ^ 7 cm ... -2. Makhalidwe ogwirira ntchito: Chithunzi chojambulidwa kwambiri cha Get / SI chitha kukwaniritsa: Kugwira ntchito, 0.8a / W nthawi ya 1550 nm; Bandwidth,> 60 ghz; Zakumaso zamakono, <1 <μa ku -1 v kukondera.

Kuphatikiza ndi nsanja ya Sicon

Kuphatikiza kwaMakina othamanga kwambiriNdi nsanja zochokera ku Silicon zochokera ku Wiltoelectics zimathandizira makompyuta oyenda bwino komanso azisokoneza. Njira ziwiri zazikuluzikulu ndizotsatira: Kuphatikizika kwakumapeto (FORY), komwe chithunzicho chimapangidwa nthawi yomweyo chimapangidwa mwapadera pa gawo lapansi la silika kuloleza kutentha kwambiri, koma kumatenga chip. Kuphatikiza kwa kumapeto (Beol). Photoodteganirs amapangidwa pamwamba pazitsulo kuti mupewe kulowerera ndi ma cmos, koma ndizochepa pakuchepetsa kutentha.

Chithunzi 2: Kuyankha ndi Bandwidth ya Get / SI Photodtector

Ntchito ya data

Makoswe othamanga kwambiri ndi gawo lalikulu m'badwo wotsatira wa data. Mapulogalamu akuluakulu amaphatikizapo: matembenuzidwe owoneka bwino: 100g, 400g ndi mitengo yayikulu, kugwiritsa ntchito kusinthasintha kwa Pam-4; AChithunzi cha bandwidth(> 50 ghz) ndizofunikira.

Silicon-zochokera ku magemu ophatikizika: Kuphatikiza kwa wojambula ndi wowongolera ndi zinthu zina; Injini yamphamvu, yolimbitsa thupi kwambiri.

Makona ogawidwa: kuphatikizidwa kwa mavesi owoneka bwino pakati pa kugwiritsa ntchito polumikiza, kusungidwa, ndi kusungirako; Kuyendetsa njira yofunikira kuti ikhale ndi mphamvu, mabotolo apamwamba kwambiri.

Chikondi m'tsogolo

Tsogolo la Kuphatikiza kwa Optoectronic kwambiri-liwiro liziwonetsa zochitika zotsatirazi:

Mitengo yapamwamba ya data: Kuyendetsa chitukuko cha 800g ndi 1.6t; Assingteganirs okhala ndi ma bandwidths oposa 100 ghz amafunikira.

Kuphatikizidwa Kwabwino: Kuphatikizidwa kwa chip kwa III-v zakuthupi ndi silicon; Ukadaulo wapamwamba wa 3D.

Zipangizo zatsopano: Kufufuza zinthu ziwiri (monga graphene) pazomwe sizabwino; Gulu latsopano la IV iv Alloy powonjezera.

Ntchito zotuluka: Lidar ndi mapulogalamu ena akuwona akuyendetsa chitukuko cha acd; Ma Microwave Photon Yofunika Kufuna Kutsanzira Kwambiri.

Mafashoni othamanga kwambiri, makamaka ge kapena SI PROMETERARORS-yofunikira kwambiri ya Silicon-zochokera ku maptoectonics okhalapo. Kupitiliza kupita patsogolo ku zida, kapangidwe ka chipangizo, ndi matekinoloje ophatikiza ndikofunikira kuti mukwaniritse zofuna za bandwidth zofuna za ma bandwids zapamsondo ndi ma telefoni. M'munda ukupitiliza kusinthika, titha kuyembekezera kuwona zithunzi zokhala ndi mandwidth apamwamba, phokoso lotsika, komanso masitepe opanda pake okhala ndi madera a makwerero.
