Entshaii-photodetectorsukuguqula iteknoloji yonxibelelwano kunye nokuva i-optical fiber
Ngenkqubela phambili eqhubekayo yesayensi netekhnoloji, iinkqubo zonxibelelwano lwefayibha ye-optical kunye neenkqubo zokuva ifayibha ye-optical ziyatshintsha ubomi bethu. Ukusetyenziswa kwazo kuye kwangena kuzo zonke iinkalo zobomi bemihla ngemihla, ukusuka kunxibelelwano lwe-intanethi ukuya kuxilongo lwezonyango, ukusuka kwi-automation yemizi-mveliso ukuya kuphando lwesayensi. Kutshanje, uhlobo olutsha lweisixhobo sokubona iifotoiguqule zombini iinkqubo.
Esi sixhobo sokubona iifoto sidibanisai-PIN photodiodekunye nesekethe yesandisi-lizwi esiphantsi se-bandwidth yokusebenza ephezulu kunye nokulahleka okuphantsi kokufakwa. Oku kuthetha ukuba iyakwazi ukubamba isignali yokukhanya ngexesha elifutshane kakhulu kwaye iyiguqule ibe sisignali yombane, ngaloo ndlela ifezekisa ukuguqulwa kwe-photoelectric ngesantya esiphezulu nangokufanelekileyo.
Ukongeza, uluhlu lwe-photodetector lokufumanisa ubude be-wavelength lugubungela i-300nm ukuya kwi-2300nm, lugubungela phantse zonke ii-wavelength ezibonakalayo kunye ne-infrared. Olu phawu luvumela ukuba isetyenziswe kwiinkqubo ezahlukeneyo ze-optical kunye ne-sensing.
I-photodetector inomsebenzi wokucubungula isignali ye-analog kunye nokukhulisa, nto leyo enokwandisa imiqondiso yokukhanya ebuthathaka ngokwaneleyo ukuba ifunyanwe sisixhobo ngexesha elifutshane kakhulu. Oku kuyivumela ukuba idlale indima ebalulekileyo kwiindawo ezifana nonxibelelwano lwe-optical, uhlalutyo lwe-spectral, i-lidar njalo njalo.
Ukongeza ekubeni namandla, esi sixhobo sokubona iifoto sinobuchule kakhulu kuyilo. Iqokobhe lenzelwe ukuthintela uthuli kunye nokuphazamiseka kwe-electromagnetic, okunokukhusela ngempumelelo isekethe yangaphakathi kukuphazamiseka kwangaphandle. Kwangaxeshanye, ujongano lwayo lwe-SMA output lwenza kube lula ukunxibelelana nezinye izixhobo.
Kufanelekile ukukhankanya ukuba iqokobhe lale photodetector linomngxuma onemisonto, ukuze likwazi ukuxhonywa kwiqonga le-optical okanye kwizixhobo zovavanyo, nto leyo eyenza kube lula kakhulu ukusebenza kovavanyo.
Lilonke, esi sitshixo-mfanekiso sitsha sisixhobo esinamandla sokwandisa iinkqubo zonxibelelwano lwefayibha ye-optical kunye neenkqubo zokuva ifayibha ye-optical. I-bandwidth ephezulu yokusebenza kunye nokulahleka okuphantsi kokufakwa kwenza ukuguqulwa kwe-photoelectric ngesantya esiphezulu nangokufanelekileyo, kwaye uluhlu olubanzi lwamaza ombane kunye nokwanda okuphezulu kwenza ukuba ikwazi ukuziqhelanisa neemeko ezahlukeneyo zesicelo. Uyilo oluhle kakhulu kunye nokufakelwa okulula kuyawandisa kakhulu amava omsebenzisi. Ukwaziswa kwesi sitshixo-mfanekiso ngokungathandabuzekiyo kuya kukhuthaza ngakumbi uphuhliso lonxibelelwano lwefayibha ye-optical kunye netekhnoloji yokuva, okusikhokelela kwihlabathi elitsha lokukhanya.
