Tsarin fasaha na tsarin L-band EDFA amplifier

1. Erbium-doped fiber
Erbium wani nau'in ƙasa ne da ba kasafai ba tare da lambar atomic na 68 da nauyin atomic na 167.3.An nuna matakin makamashi na lantarki na erbium ion a cikin adadi, kuma sauyawa daga matakin ƙananan makamashi zuwa matakin makamashi na sama ya dace da tsarin ɗaukar haske.Canji daga matakin makamashi na sama zuwa matakin ƙananan makamashi ya dace da tsarin fitar da haske.

EDFA yana amfani da erbium ion-doped fiber azaman matsakaicin riba, wanda ke haifar da jujjuyawar jama'a a ƙarƙashin hasken famfo.Yana gane haɓakar haɓakar radiation a ƙarƙashin ƙaddamar da hasken sigina.
Erbium ions suna da matakan makamashi guda uku.Suna a matakin mafi ƙarancin makamashi, E1, lokacin da ba su jin daɗin kowane haske.Lokacin da fiber ke ci gaba da jin daɗin famfo hasken hasken Laser, abubuwan da ke cikin ƙasa suna samun kuzari da canzawa zuwa matakin makamashi mafi girma.Irin su sauyawa daga E1 zuwa E3, saboda barbashi ba shi da kwanciyar hankali a babban matakin makamashi na E3, zai fada cikin sauri zuwa yanayin E2 mai sauƙi a cikin tsarin canji maras radiyo.A wannan matakin makamashi, barbashi suna da ɗan gajeren rayuwa.Saboda ci gaba da tashin hankali na tushen hasken famfo, adadin ƙwayoyin da ke cikin matakin makamashi na E2 zai ci gaba da karuwa, kuma adadin kwayoyin halitta a matakin makamashi na E1 zai karu.Ta wannan hanyar, ana samun rarrabawar yawan jama'a a cikin fiber na erbium-doped, kuma ana samun yanayin koyan haɓakawar gani.
Lokacin da siginar shigar da siginar photon E = hf daidai yake daidai da bambancin matakin makamashi tsakanin E2 da E1, E2-E1 = hf, barbashi a cikin yanayin metastable zasu canza zuwa yanayin ƙasa E1 a cikin nau'in radiation mai kuzari.Radiation da shigarwa Photons da ke cikin siginar suna kama da photons, don haka yana ƙaruwa da lambar photons sosai, yana sa siginar shigarwar ta zama siginar gani mai ƙarfi a cikin fiber na erbium-doped, yana fahimtar haɓakar siginar gani kai tsaye. .
