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.
2. ka'idar EDFA
EDFA yana amfani da erbium ion-doped fiber a matsayin 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.
