1. Ifayibha exutywe ne-erbium
I-Erbium sisiqalelo somhlaba esinqabileyo esinenombolo yeathomu engama-68 kunye nobunzima beathomu obuyi-167.3. Inqanaba lamandla e-elektroniki le-erbium ion liboniswe kumfanekiso, kwaye utshintsho ukusuka kwinqanaba lamandla asezantsi ukuya kwinqanaba lamandla aphezulu luhambelana nenkqubo yokufunxa ukukhanya. Utshintsho ukusuka kwinqanaba lamandla aphezulu ukuya kwinqanaba lamandla asezantsi luhambelana nenkqubo yokukhupha ukukhanya.
2. Umgaqo we-EDFA
I-EDFA isebenzisa i-erbium ion-doped fiber njenge-gain medium, evelisa i-population inversion phantsi kokukhanya kwepompo. Ifezekisa ukwanda kwemitha evuselelweyo phantsi kokukhanya kwesiginali.
Ii-ion ze-Erbium zinamanqanaba amathathu amandla. Zikwinqanaba lamandla asezantsi, i-E1, xa zingavuselelwanga kukukhanya. Xa ifayibha ivuselelwa rhoqo yilaser yomthombo wokukhanya kwepompo, amasuntswana akwimeko yomhlaba afumana amandla kwaye atshintshele kwinqanaba lamandla aphezulu. Njengokutshintsha ukusuka kwi-E1 ukuya kwi-E3, kuba isuntswana ayizinzanga kwinqanaba lamandla aphezulu le-E3, iya kuwa ngokukhawuleza kwisimo se-metastable E2 kwinkqubo yotshintsho olungenamisebe. Kweli nqanaba lamandla, amasuntswana anobomi obude bokusinda. Ngenxa yokuvuseleleka okuqhubekayo komthombo wokukhanya kwepompo, inani lamasuntswana kwinqanaba lamandla le-E2 liya kuqhubeka likhula, kwaye inani lamasuntswana kwinqanaba lamandla le-E1 liya kwanda. Ngale ndlela, ukusasazwa kwe-population inversion kuyenzeka kwifayibha efakwe i-erbium, kwaye iimeko zokufunda ukukhulisa ukukhanya ziyafumaneka.
Xa amandla e-photon yesignali yokufaka i-E=hf elingana ngokuchanekileyo nomahluko wenqanaba lamandla phakathi kwe-E2 kunye ne-E1, i-E2-E1=hf, amasuntswana akwimeko eguquguqukayo aya kutshintshela kwimo yomhlaba i-E1 ngohlobo lwemitha evuselelweyo. Imitha kunye ne-input Ii-photon ezikwisignali ziyafana nee-photon, ngaloo ndlela zinyusa kakhulu inani lee-photon, okwenza i-input optical signal ibe yisignali enamandla ye-output optical kwi-fiber efakwe i-erbium, iqonda ukwanda ngokuthe ngqo kwesignali ye-optical.
2. Umzobo wenkqubo kunye nentshayelelo yesixhobo esisisiseko
2.1. Umzobo wesicwangciso senkqubo ye-L-band optical fiber amplifier yile ilandelayo:
2.2. Umzobo wesicwangciso senkqubo yomthombo wokukhanya we-ASE wokukhupha okuzenzekelayo kwefayibha efakwe i-erbium ngolu hlobo lulandelayo:
