1. Fiber e entsoeng ka Erbium
Erbium ke ntho e sa tloaelehang ea lefatše e nang le nomoro ea athomo ea 68 le boima ba athomo ea 167.3.Boemo ba matla a elektronike a erbium ion bo bontšoa setšoantšong, 'me phetoho ho tloha boemong bo tlaase ba matla ho ea boemong bo phahameng ba matla bo lumellana le mokhoa oa ho monya ha leseli.Phetoho ho tloha boemong bo ka holimo ba matla ho ea boemong bo tlaase ba matla bo lumellana le mokhoa oa ho ntša khanya.
2. Molao-motheo oa EDFA
EDFA e sebelisa fiber ea erbium ion-doped e le mokhoa oa ho fumana chelete, o hlahisang phetoho ea baahi tlas'a leseli la pompo.E lemoha ho holisoa ha mahlaseli a matla tlas'a ho kenngoa ha lebone la lets'oao.
Li-ion tsa Erbium li na le matla a mararo.Ba boemong bo tlaase ka ho fetisisa ba matla, E1, ha ba sa thabisoe ke leseli leha e le lefe.Ha fiber e tsoela pele ho thabisoa ke laser mohloli oa leseli la pompo, likaroloana tse sebakeng sa fatše li fumana matla le ho fetela boemong bo phahameng ba matla.Joalo ka phetoho ho tloha ho E1 ho ea ho E3, hobane karoloana e sa tsitsa boemong bo phahameng ba matla a E3, e tla potlakela ho oela sebakeng sa metastable E2 ka mokhoa o se nang mahlaseli a phetoho.Boemong bona ba matla, likaroloana li na le nako e telele ea ho phela.Ka lebaka la ho tsosoa ho tsoelang pele ha mohloli oa leseli la pompo, palo ea likaroloana tsa matla a E2 e tla tsoela pele ho eketseha, 'me palo ea likaroloana tsa matla a E1 e tla eketseha.Ka tsela ena, kabo ea inversion ea baahi e fumaneha ho erbium-doped fiber, 'me maemo a ho ithuta ho phahamisa mahlo a fumaneha.
Ha lets'oao la ho kenya matla la photon E = hf le lekana hantle le phapang ea boemo ba matla pakeng tsa E2 le E1, E2-E1 = hf, likaroloana tse maemong a metastable li tla fetela sebakeng sa fatše sa E1 ka mokhoa oa mahlaseli a tsositsoeng.Mahlaseli a mahlaseli le ho kenya letsoho Li-photons tse ka har'a pontšo li tšoana le li-photon, kahoo li eketsa haholo palo ea photons, ho etsa hore pontšo ea optical e be pontšo e matla ea optical ka har'a fiber ea erbium-doped, e hlokomelang ho phahamisa ka ho toba ha lets'oao la optical. .
