Inkqubela-phambili yakutshanjeIimvakalelo eziphezulu ze-Avalanche

Igumbi legumbi eliphezulu lobushushu 1550 NMI-Avalanche Photediode ictorctor

Kwi-infrared ekufuphi (i-wirr) ye-nece, ibhendi ephezulu ye-Avalanche Dods isetyenziswa ngokubanzi kunxibelelwano lwe-Optoect kunye nezicelo ze-lidar. Nangona kunjalo, i-Ivalanche ye-Avalanche ye-Avalanche (i-APD) ilawulwa yi-InAllium Gallium Avalanches Ivarder Ivasions ye-Ivalade (I-Inp), i-Inaim phossin, ikhokelela ekubonakalisweni kwemvakalelo yesixhobo. Over the years, many researchers are actively looking for new semiconductor materials that are compatible with InGaAs and InP optoelectronic platform processes and have ultra-low impact ionization noise performance similar to bulk silicon materials.

I-Innovative 1550 NM Avalanche Photoctor umfanekiso we-Photoriode inceda ukukhula kweenkqubo ze-lidar

Iqela labaphandi e-United Kingdom kunye ne-United States lize kwixesha lokuqala liphuhlise ngempumelelo imvakalelo ye-Ultra ye-Ultra ye-Ultra ye-Ultra ye-Altra ye-1550 NM APDEtectctotect (I-Avalanche Pempletetect), iqhekeza elithembisa ukuba liphucule kakhulu ukusebenza kweenkqubo ze-lidir kunye nezinye izicelo ze-Optoect.

Izinto ezintsha zibonelela ngoncedo oluphambili

Eyona nto ibalulekileyo kolu phando kukusetyenziswa okutsha lwezixhobo. Abaphandi bakhetha i-gasb njengomaleko wokufumana kunye ne-algaasb njenge-sportler. Oluyilo lwahlukileyo kwi-ICAAS / i-inp kwaye uzisa izibonelelo ezibalulekileyo:

I-Action ye-Ackessb ye-Ackessb: IGasb inolwazi olufanayo kwi-Insaas, kunye notshintsho oluvela kwi-Gassb Gacermer kwi-Algaisb

I-Funder ye-Adgassb ye-Sport: I-Algaasfu ye-Algaasfur ye-Algaight iphezulu kwi-Inp yeSiko kunye ne-Inallas ye-Inali. Kuboniswa ikakhulu ngokufumana inzuzo ephezulu kubushushu begumbi, i-bandwidth ephezulu kunye ne-Ultra-ephantsi.

Ngeempawu zentsebenzo ezifanelekileyo

EntshaI-APD yefoto(Ivalanche Phototiode Strictor) ikwabonelela ngokuphuculwa okubonakalayo kwi-metrics yentsebenzo:

I-1. Inzuzo ePltra-In Eltra-Right e-Ultra-Right ifezekiswe kubushushu begumbi, kwaye kutshanje uGqr Jin xiao uphucule i-M = 1212.

I-2. Ingxolo enkulu kakhulu: ibonisa ingxolo ephantsi kakhulu (F <3, ifumane m = 70; f <4, ifumane m = 100).

3. Ukusebenza kakuhle kwexabiso: Ngaphantsi kwenzuzo ephezulu, ukusebenza ngokukuko kukuphakama kwi-5935.3%. Uzinzo lobushushu olunamandla: Imvakalelo yokuqhekezwa kwiqondo lobushushu elisezantsi limalunga ne-11.83 MV / K.

Amathemba okusebenza ngokubanzi

Le APD entsha ineempembelelo ezibalulekileyo kwiinkqubo ze-lidi kunye nezicelo zePhoton:

1. Ukuphuculwa kwengxolo yengxolo: Inzuzo ephakamileyo kunye neempawu zengxolo eziphantsi kunye neempawu eziphantsi zengxolo ziphucula ikakhulu umlinganiso wengxolo, ebaluleke kakhulu kwindalo ePhoton-Engling Rogehouse.

2. Ukuhambelana okuqinileyo: Ifoto ye-APD entsha (ivalanchetetecttectote) yenzelwe ukuba ihambelane nePlasffide yangoku ye-Indion Fosfide (i-INP) i-Optoelectory, iqinisekisa ukudityaniswa kwenkqubo yonxibelelwano.

3. Ukusebenza okuphezulu kokusebenza: Inokusebenza ngokufanelekileyo kubushushu begumbi ngaphandle kweendlela zokupholisa ezintsonkothileyo, ukwenziwa lula kwizicelo ezahlukeneyo zenziwe.

Ukuphuhliswa kwale ncwadi intsha ye-1550 NM SACD ye-APD Olu luhlu lulindeleke ukuba lukhulise amandla eenkqubo ze-lidi, ngakumbi kwiinkqubo ze-lida engekho mthethweni, kunye nonxibelelwano lwesithuba esimahla.
