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 i-Avalanche ye-Avalanche ye-Avalanche (i-APD) ilawulwa yi-Ivalium Gallium Avalanches ye-Diode yeNdawo yeMimandla yeNdawo yeMimandla ye-Ivalay (i-InP) i-Insminum Alsenic ( I-Inalas), isiphumo sokuncitshiswa okukhulu kwimvakalelo 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.
