Sekema sa tekheniki sa L-band EDFA amplifier system

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.

EDFA e sebelisa erbium ion-doped fiber 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 leseli la pontšo.
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 ka matla a matla a E3, e tla oela ka potlako ho boemo ba 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 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 Lifoto tse ka har'a lets'oao li ts'oana le li-photon, ka hona li eketsa palo ea li-photon haholo, ho etsa hore lets'oao la optical le be lets'oao le matla la phallo ea optical ka har'a erbium-doped fiber, ho lemoha ho holisoa ka ho toba ha lets'oao la optical. .
