1. Erbium-doped fiber
ʻO ka Erbium kahi mea honua laha ʻole me ka helu atomika o 68 a me ke kaumaha atomika o 167.3. Hōʻike ʻia ka pae ikehu uila o ka erbium ion ma ke kiʻi, a ʻo ka hoʻololi ʻana mai ka pae ikehu haʻahaʻa a i ka pae ikehu luna e pili ana i ke kaʻina hana absorption o ka mālamalama. ʻO ka hoʻololi ʻana mai ka pae ikehu kiʻekiʻe i ka pae ikehu haʻahaʻa e pili ana i ke kaʻina hana hoʻokuʻu māmā.

2. Kumu EDFA

Hoʻohana ʻo EDFA i ka fiber erbium ion-doped fiber ma ke ʻano he kumu waiwai, kahi e hoʻohuli ai i ka heluna kanaka ma lalo o ke kukui pamu. Hoʻomaopopo ia i ka hoʻonui ʻia ʻana o ka radiation ma lalo o ka induction o ke kukui hōʻailona.
ʻEkolu mau pae ikehu ko Erbium ions. Aia lākou ma ka pae ikehu haʻahaʻa loa, E1, ke hoʻohauʻoli ʻole lākou i kekahi kukui. Ke hoʻohauʻoli mau ʻia ka fiber e ka laser puna kukui pamu, loaʻa i nā ʻāpana o ka ʻāina ka ikehu a hoʻololi i kahi kiʻekiʻe o ka ikehu. E like me ka hoʻololi ʻana mai E1 a hiki i E3, no ka mea, ʻaʻole paʻa ka ʻāpana i ka pae ikehu kiʻekiʻe o E3, e hāʻule koke ia i ka mokuʻāina metastable E2 i loko o kahi kaʻina hoʻololi non-radiative. Ma kēia pae ikehu, he lōʻihi ke ola o nā ʻāpana. Ma muli o ka hoʻoulu mau ʻana o ke kumu kukui pump, e hoʻomau ka nui o nā mea i ka pae ikehu E2, a e piʻi aʻe ka nui o nā ʻāpana ma ka pae ikehu E1. Ma kēia ala, ʻike ʻia ka hoʻoili ʻana o ka heluna kanaka i ka fiber erbium-doped, a loaʻa nā kūlana no ke aʻo ʻana i ka hoʻonui optical.
Ke like pono ka ikehu photon hoailona E=hf me ka like ole o ka ikehu ma waena o E2 a me E1, E2-E1=hf, e hoololi ana na mea liilii ma ka mokuaina metastable i ka mokuaina honua E1 ma ke ano o ka kukuna hooulu ana. ʻO ka radiation a me ka hoʻokomo Ua like nā kiʻi i loko o ka hōʻailona me nā kiʻi kiʻi, no laila e hoʻonui nui i ka helu o nā kiʻi, e hana ana i ka hōʻailona hōʻailona hoʻokomo i lilo i hōʻailona optical puka ikaika i loko o ka fiber erbium-doped, eʻike ana i ka hoʻonui pololeiʻana o ka hōʻailona optical. .
