L-band edfa amplifier sisitemu ya tekinoroji ya tekiniki

1. Fibre ya Erbium
Erbium nikintu kidasanzwe cyisi gifite umubare wa 68 nuburemere bwa atomic bwa 167.3. Urwego rwingufu za erbium rwa erbium rwerekanwe ku gishushanyo, hamwe ninzibacyuho kuva kurwego rwo hasi kurwego rwo hejuru rwingufu zijyanye nuburyo bujyanye numucyo. Impinduka kuva kurwego rwo hejuru kurwego rwo hasi ruhuye nibikorwa byo kumurika.

2. Ihame rya Edfa

EDFA ikoresha fibre ya erbium nka chaction nkubwiza, butanga ihindagurika ryabaturage munsi yumucyo. Irasaba ko ikubiyemo imirasire ikubiyemo induction yimyandikire.
Erbium veon ifite imbaraga eshatu. Bari kurwego rwo hasi rwingufu, E1, mugihe badashimishijwe numucyo uwo ariwo wose. Iyo fibre ikomeje gushimishwa na pompe yoroheje Inkomoko ya laser, ibice biri hasi byunguka imbaraga ninzibacyuho kurwego rwo hejuru. Nk'inzibacyuho kuva E1 kugeza E3, kubera ko ibice bidahungabana kurwego rwo hejuru rwa E3, bizahita bigwa kuri leta ya metastable E2 muburyo bwo kwihindura. Kurwego rwingufu, ibice bifite ubuzima buhoraho bwo kubaho. Bitewe no guhora ushimangira inkomoko ya pompe, umubare wibice kurwego rwingufu za E2 bizakomeza kwiyongera, kandi umubare wibice kurwego rwingufu ziziyongera. Muri ubu buryo, ikwirakwizwa ryabaturage ryabangamiye muri fibre ya erbium, kandi ibintu byo kwiga byongewe birahari.
Iyo kwinjiza ingufu za photon ingufu e = HF ihwanye neza nitandukaniro ryingufu zingana na E2 na E1, E1 = HF, ibice muburyo bwo guhuza leta e1 muburyo bwimirasire yashidikanywaho. Imirasire hamwe nibitekerezo byafotowe mubimenyetso birasa kubafotora, bityo bikaba byinshi byerekana ibimenyetso bya optique bihinduka ibimenyetso bya optique muri fibre ya erbium, imenya kongererwa ibimenyetso bya oplique.
