1. I-Erbium-doped fiber
I-Erbium sisiqalelo somhlaba esinqabileyo esinenombolo yeathomu engama-68 kunye nobunzima beathom obuyi-167.3.Inqanaba lamandla ombane we-erbium ion liboniswa kumzobo, kwaye ukuguquka ukusuka kwinqanaba eliphantsi lamandla ukuya kwinqanaba eliphezulu lamandla lihambelana nenkqubo yokufunxa ukukhanya.Utshintsho ukusuka kwinqanaba eliphezulu lamandla ukuya kwinqanaba eliphantsi lamandla lihambelana nenkqubo yokukhutshwa kokukhanya.
2. Umgaqo we-EDFA
I-EDFA isebenzisa i-erbium ion-doped fiber njengendlela yokuzuza, evelisa inversion yabemi phantsi kokukhanya kwempompo.Iqaphela ukukhulisa i-radiation evuselelweyo phantsi kokufakwa komqondiso wokukhanya.
I-Erbium ion inemigangatho emithathu yamandla.Bakwinqanaba eliphantsi lamandla, i-E1, xa bengavuyiswanga nakuphi na ukukhanya.Xa i-fiber iqhubeka ivuyiswa yi-laser yomthombo wokukhanya wempompo, amasuntswana akwimeko yomhlaba afumana amandla kwaye atshintshele kwinqanaba eliphezulu lamandla.Njengotshintsho olusuka ku-E1 ukuya kwi-E3, ngenxa yokuba i-particle ayizinzile kwizinga eliphezulu lamandla e-E3, iya kuwela ngokukhawuleza kwi-metastable state E2 kwinkqubo yokuguqulwa kwe-radiative.Kweli nqanaba lamandla, amasuntswana aphila ubomi obude.Ngenxa yokuphazamiseka okuqhubekayo komthombo wokukhanya wempompo, inani leengqungquthela kwinqanaba lamandla e-E2 liya kuqhubeka nokunyuka, kwaye inani leengqungquthela kwinqanaba le-E1 liya kwanda.Ngale ndlela, ukuhanjiswa kwe-inversion yabemi kubonwa kwi-erbium-doped fiber, kwaye iimeko zokufunda ukukhulisa i-optical ziyafumaneka.
Xa isignali yegalelo le-photon energy E=hf ilingana ngokuchanekileyo nomlinganiselo wenqanaba lamandla phakathi kwe-E2 kunye ne-E1, E2-E1=hf, amasuntswana akwimo ye-metastable aya kutshintshela kumhlaba we-E1 ngendlela yosasazo oluvuselelweyo.Ukukhanya kwemitha kunye negalelo Iifotoni ezikwisiginali ziyafana neefotoni, ngaloo ndlela zonyusa kakhulu inani leefotoni, zenza isiginali ye-optical igalelo ibe ngumqondiso onamandla ophumayo kwifayibha ye-erbium-doped, ukuqonda ukukhulisa ngokuthe ngqo umqondiso wokukhanya. .
2. Umzobo wenkqubo kunye nokuqaliswa kwesixhobo esisisiseko
2.1.Umzobo weskim senkqubo ye-L-band optical fiber amplifier yile ilandelayo:
2.2.Umzobo wenkqubo yomthombo wokukhanya we-ASE yokuphuma ngokuzenzekelayo kwe-erbium-doped fiber imi ngolu hlobo lulandelayo:
