1. Erbium-yakarongedzwa fiber
Erbium ishoma yepasi chinhu chine nhamba yeAtomi ye68 uye kurema kwe167.3. Iyo erbium ion's yemagetsi emagetsi chikamu chinoratidzwa mumufananidzo, uye shanduko kubva kune yakadzika simba resimba kune iyo yepamusoro simba remawere inoenderana neyakagadziriswa maitiro echiedza. Shanduko kubva kune iyo yepamusoro simba chikamu kune yakaderera simba chikamu chinoenderana nekunyorerana kwechiedza chechiitiko.
2. Edfa nheyo
Edfa anoshandisa erbium ion-temped fiber seanowana svikiro, inoburitsa huwandu hwehuwandu hwehuwandu hwepombi. Izvo zvinonyatsoomerwa radiation kukwirisa pasi pekunyepedzera kweSignal Chiedza.
Erbium ion ine ese maviri esimba mazinga. Ivo vari pane yakaderera simba remugodhi, E1, kana vasingafare nemwenje. Kana iyo fiber ichiramba ichinakidzwa neiyo pombi mwenje tsime Laser, zvidimbu zviri pasi state kuwana simba uye shanduko kune yakakwirira simba remagetsi. Sekushandurwa kubva kuE3 kusvika E3, nekuti iyo simle haina kugadzikana kune yakakwira simba remuti e3, inokurumidza kuwira kune mitezo ye2 e2 nenzira isiri-radiate transition. Pane imwe simba esimba, zvidimbu zvine hupenyu hwakareba hwekupona. Nekuda kwekuenderera mberi kwechiitiko chepombi yemwenje, nhamba yezvikamu zveE2 Energy Level icharamba ichiwedzera, uye nhamba yezvikamu zveE1 simba ichawedzera. Nenzira iyi, huwandu hwevanhu vekuparadzaniswa kwehuwandu hunoonekwa muErbium-Diber Filber, uye mamiriro ekudzidza Optical kukwiridzwa kunowanikwa.
Kana iyo yekuisa chiratidzo phonal emagetsi e = hf ndeyechokwadi yakaenzana neyekuwedzera musiyano uripo pakati peE2 neE1 Iyo radiation uye kuisa iyo mafoto muchiratidzo zvakafanana kune iyo pikicha, ichigadzira iyo yekuisa nhamba yechiitiko chekubuda mune yeErbium fiber, ichiziva iyo yakananga kugadzirwa kwechiratidzo chechiratidzo.
