Kutentha kwa chipinda chachikulu kwambiri 1550 nmAvalanche Photodiodiode chojambula

Pafupi ndi infrared (swir), chidwi chachikulu cha ma alanche othamanga kwambiri amagwiritsidwa ntchito kwambiri mu kulumikizana kwa optoelectonic komanso ntchito zoikika. Komabe, avalche omwe ali pafupi ndi ap Inalas), zomwe zimapangitsa kuti kuchepetsedwa kwa chipangizocho. Kwa zaka zambiri, ofufuza ambiri amayang'ana zida zatsopano za semiconduct zomwe zimagwirizana ndi ingtoectic Platform Platsions Platgestiction Platsions Platsions Platsions Platsions Platsions Platsions Platsions Platsions Platsions Platsion Plassion ndi kukhala ndi phokoso lotsika la mankhwala othandizira ofanana ndi zida zambiri za silicon.

Wogwiritsa ntchito bwino 1550 NM Avanche Photodiode amathandiza kukula kwa madera a liDidar

Gulu la ofufuza ku United Kingdom ndi United States likhala ndi nthawi yoyamba yomwe idayamba kupanga chidwi chatsopano cha ultra-ives 1550 nm apd chithunzi (Chithunzithunzi cha Avalche) Chotsani zomwe zimalonjeza kuti ziziwongolera kwambiri machitidwe a madera ena ndi mapulogalamu ena a OPtoelectronic.

Zinthu zatsopano zimapereka zabwino

Chofunika kwambiri cha kafukufukuyu ndi kugwiritsa ntchito zinthu zatsopano. Ofufuzawo adasankha Gaass ngati mayamwidwe osanjikiza ndi algaassb ngati ochulukitsa. Kapangidwe kameneka kumasiyana ndi miyambo ya Mile / INP ndikubweretsa zabwino:

1.Gassb kuyamwidwe: Gaassb ali ndi mayamwidwe ofanana ndi a Ikuas, ndikusintha kuchokera ku Gasb Kuyamwa ku Algaassb (Clueter Spend) ndikosavuta kuwongolera ndikusintha kwa chipangizocho.

2.Lalgassb clundu cluyer: Algaassb clundu cluble slue ndipamwamba kuposa inp ya infictive ndi invalas clearquequiliquetion mu magwiridwe antchito. Zimawonedwa bwino kwambiri kutentha kwa firiji, phokoso lalitali komanso phokoso lochulukirapo.

Ndi zisonyezo zabwino kwambiri

AtsopanoPhotodtector.

1. Ultra-yayikulu: Kupeza ndalama kwambiri kwa 278 kunatheka kutentha, ndipo posachedwa Dr. JIN XIN XIAO idasintha makonzedwe ndi njira, ndipo phindu lalikulu lidachuluka mpaka m = 1212.

2. Nyuzi zochepa kwambiri: zimawonetsa phokoso lotsika kwambiri (f <3, kupeza m = 70; f <4).

3. Kugwira ntchito kwambiri: Kutsika mtengo kwambiri, kuchuluka kwa kuchuluka kwake kuli kokwera ngati 5935.3%. Kutentha kwamphamvu: Kusokoneza khutu pamtunda wochepa ndi pafupifupi 11.83 MV / k.

Zofunika Kwambiri

APD yatsopanoyi ili ndi tanthauzo lofunikira kwa ma systems ndi ma Photon:

1. Chiwerengero choyenera-chizindikiritso: Kuchuluka kwa phokoso komanso phokoso laling'ono kwambiri kusintha kuchuluka kwa chizindikiritso, komwe ndikofunikira kuti pakhale ntchito mu Photon-Utoto Wogulitsa Mafuta.

2. Kugwirizana kwamphamvu: The New Photodetector (Collanche Photodtector) idapangidwa kuti ikhale yogwirizana ndi phosphide yamakono ya phosfaide (insp) nsanja yolumikizirana ndi njira zamalonda.

3. Kuchita bwino kwambiri: kumatha kugwira ntchito motaka firiji popanda njira zozizira zothandizira.

Kukula kwa 1550 NM Stem Apd Photodtector (Avranche Photodtector) akuimiranso zopinga zazikulu zomwe zimagwirizanitsidwa ndi phokoso lowonjezerapo ndikupanga zithunzi. Kupanga kumeneku kumayembekezeredwa kuti ulimbikitse kuthekera kwa maluso a madera, makamaka m'manda wamba, komanso maulendo aulere.
