Breakthrough photoelectric nrhiav tshuab (Avalanche photodetector): Ib tshooj tshiab hauv kev nthuav tawm lub teeb tsis muaj zog
Hauv kev tshawb fawb txog kev tshawb fawb, kev tshawb pom tseeb ntawm lub teeb pom kev tsis muaj zog yog tus yuam sij rau qhib ntau yam kev tshawb fawb. Tsis ntev los no, ib qho kev tshawb fawb tshawb fawb tshiab tau ua rau muaj kev hloov pauv mus rau kev tshawb pom cov teeb liab tsis muaj zog. CovLub avalanche photodetectorseries tsim los ntawm pab pawg tshawb fawb paub zoo hauv Suav teb, nrog rau nws qhov kev ua tau zoo thiab qhov zoo, yuav qhib ib tshooj tshiab rau kev tshawb pom lub teeb pom kev tsis muaj zog.
Avalanchephotodetectorseries khoom, raws li avalanche amplification txoj cai ntawmAPD, magnification yog 10 mus rau 100 npaug ntawm qhov zoo tib yam PIN photoelectric sib sib zog nqus detector, nrog siab rhiab heev, tsis tshua muaj suab nrov, zoo nrhiav kom tau zoo thiab lwm yam zoo. Qhov tshwm sim ntawm cov khoom siv no yuav pab cov neeg tshawb nrhiav zoo dua thiab txheeb xyuas lub teeb pom kev tsis muaj zog, thiab ntxiv dag zog rau qhov tob ntawm kev tshawb fawb tshawb fawb.
Cov yam ntxwv tseem ceeb ntawm cov khoom siv no yog cov suab nrov qis, siab nce thiab kho qhov muag fiber ntau, spatial coupling xaiv. Qhov no txhais tau hais tias txawm tias nws yog ib puag ncig kev sim lossis ib puag ncig sab nraud, cov khoom lag luam tuaj yeem ua tiav qhov teeb meem kho qhov muag kom pom tseeb, muab cov ntaub ntawv txhim khu kev qha rau cov kws tshawb fawb. Cov thev naus laus zis tshiab no tsis yog tsuas yog txhim kho kev tshawb pom kev ua haujlwm ntawm cov teeb liab kho qhov muag, tab sis kuj txo cov suab nrov hauv cov txheej txheem tshawb nrhiav thiab txhim kho qhov tseeb ntawm kev tshawb pom.
Tshwj xeeb, qhov ntau ntawm cov lus teb spectra npog 300-1100nm thiab 800-1700nm, nrog 3dB bandwidths mus txog 200MHz, 500MHz, 1GHz thiab 10GHz. Cov kev sib txawv no thiab cov kev txwv no ua rau cov khoom lag luam hloov mus rau qhov kev xav tau ntawm kev tshawb fawb sib txawv, thiab ntau yam kev siv, suav nrog kev pom tsis muaj zog kho qhov muag teeb liab, kev kub ceev optical pulse teeb pom kev, thiab kev sib txuas lus quantum.
Nws yog tsim nyog hais tias cov khoom muaj built-in avalanche photodiode, tsis tshua muaj suab nrov amplification Circuit Court, APD bias boost circuit, thiab nrhiav kom tau wavelength ntawm tag nrho cov series ntawm cov khoom npog 300nm-1700nm. Qhov kev tsim no ua rau cov khoom lag luam kom ua tiav qhov kev tshawb pom siab, tab sis kuj txo cov suab nrov, txhim kho qhov tseeb ntawm kev tshawb pom. Tsis tas li ntawd, qhov kev xaiv ntawm optical fiber ntau thiab spatial coupling pab kom cov khoom ua tiav cov teeb liab pom tseeb hauv ntau qhov chaw ib puag ncig.
Nyob rau hauv luv luv, txoj kev loj hlob ntawm no avalanchephotoelectric ntesseries yog undoubtedly ib tug loj breakthrough nyob rau hauv photoelectric nrhiav tshuab. Qhov tshwm sim ntawm cov khoom no muab qhov muaj peev xwm tshiab rau qhov tsis muaj zog lub teeb pom kev pom thoob ntiaj teb. Peb cia siab tias cov khoom no los ua lub luag haujlwm ntau dua hauv kev tshawb fawb txog kev tshawb fawb yav tom ntej, txhawb kev kawm txuj ci, thiab ua haujlwm zoo dua rau kev txhim kho tib neeg lub neej.
