EDFA na-eji erbium ion-doped fiber dị ka ihe na-enweta uru, nke na-emepụta mgbanwe ndị mmadụ n'okpuru ọkụ mgbapụta. Ọ na-achọpụta mmụba radieshon na-akpali akpali n'okpuru ntinye nke ìhè mgbaàmà.
Erbium ion nwere ọkwa ume atọ. Ha nọ n'ogo ike kachasị ala, E1, mgbe ọkụ ọ bụla na-enweghị obi ụtọ ha. Mgbe eriri na-anọgide na-enwe obi ụtọ site na mgbapụta ọkụ ọkụ mgbapụta laser, ihe ndị dị na ala ala na-enweta ume na mgbanwe na ọkwa ume dị elu. Dị ka mgbanwe site na E1 ka E3, n'ihi na urughuru na-ejighị n'aka na elu ume larịị nke E3, ọ ga-ngwa ngwa daa na metastable steeti E2 na a na-abụghị radiative mgbanwe usoro. N'ọkwa ike a, ihe ndị ahụ nwere ndụ dị ogologo ndụ. N'ihi mkpali na-aga n'ihu nke isi iyi ọkụ mgbapụta, ọnụ ọgụgụ nke ihe ndị dị na E2 ike larịị ga-anọgide na-abawanye, na ọnụ ọgụgụ nke ahụ na E1 ike larịị ga-abawanye. N'ụzọ dị otú a, a na-enweta nkesa ngbanwe nke ọnụ ọgụgụ mmadụ na eriri erbium-doped, na ọnọdụ maka ịmụta nkwalite ngwa anya dị.
Mgbe mgbama mgbama photon ike E = hf bụ kpọmkwem nha nha nha ike dị n'etiti E2 na E1, E2-E1 = hf, ihe ndị dị na steeti metastable ga-agbanwe gaa na steeti ala E1 n'ụdị radieshon kpaliri. Radieshon na ntinye foton ndị dị na mgbama ahụ yiri foton, si otú a na-amụba ọnụ ọgụgụ foton nke ọma, na-eme ka mgbama ngwa ngwa ntinye aghọ ihe siri ike mmepụta ihe ngosi anya na eriri erbium-doped, na-aghọta nrịbawanye nke mgbaàmà anya kpọmkwem. .
