1. I-fiber efakwe i-Erbium
I-Erbium iyisakhi somhlaba esingavamile esinenombolo ye-athomu engu-68 kanye nesisindo se-athomu esingu-167.3. Izinga lamandla kagesi le-erbium ion liboniswe esithombeni, futhi ukuguquka kusuka ezingeni eliphansi lamandla kuya ezingeni eliphezulu lamandla kuhambisana nenqubo yokumunca ukukhanya. Ushintsho kusuka ezingeni eliphezulu lamandla kuya ezingeni eliphansi lamandla luhambisana nenqubo yokukhipha ukukhanya.
2. Isimiso se-EDFA
I-EDFA isebenzisa i-fiber ene-erbium ion njenge-gain medium, ekhiqiza ukuguqulwa kwabantu ngaphansi kokukhanya kwephampu. Ikwazi ukwandisa imisebe evuselelwe ngaphansi kokufakwa kokukhanya kwesignali.
Ama-ion e-Erbium anamazinga amathathu amandla. Asezingeni eliphansi kakhulu lamandla, i-E1, lapho engavuselelwa yinoma yikuphi ukukhanya. Lapho i-fiber ivuselelwa njalo yi-laser yomthombo wokukhanya kwephampu, izinhlayiya ezisesimweni somhlaba zithola amandla futhi ziguqukele ezingeni eliphezulu lamandla. Njengokushintsha kusuka ku-E1 kuya ku-E3, ngoba inhlayiya ayizinzile ezingeni eliphezulu lamandla le-E3, izowela ngokushesha esimweni se-metastable E2 enkambisweni yokushintsha okungeyona i-radiative. Kuleli zinga lamandla, izinhlayiya zinesikhathi eside sokusinda. Ngenxa yokuvuselelwa okuqhubekayo komthombo wokukhanya kwephampu, inani lezinhlayiya ezingeni lamandla le-E2 lizoqhubeka nokukhula, futhi inani lezinhlayiya ezingeni lamandla le-E1 lizokhula. Ngale ndlela, ukusatshalaliswa kokuguqulwa kwabantu kutholakala ku-fiber efakwe i-erbium, futhi izimo zokufunda ukukhulisa ukukhanya ziyatholakala.
Uma amandla e-photon yesignali yokufaka i-E=hf elingana ncamashi nomehluko wezinga lamandla phakathi kwe-E2 ne-E1, i-E2-E1=hf, izinhlayiya ezisesimweni esiguquguqukayo zizoshintshela esimweni somhlabathi i-E1 ngesimo somsebe oshukunyisiwe. Imisebe kanye nokufakwayo Ama-photon esignalini afana nama-photon, ngaleyo ndlela andisa kakhulu inani lama-photon, okwenza isignali ye-optical yokufaka ibe isignali ye-optical enamandla ephumayo ku-fiber efakwe i-erbium, okwenza kubonakale ukukhuliswa okuqondile kwesignali ye-optical.
2. Umdwebo wesistimu kanye nesingeniso sedivayisi eyisisekelo
2.1. Umdwebo ohleliwe wohlelo lwe-L-band optical fiber amplifier umi kanje:
2.2. Umdwebo wesimiso sesistimu yomthombo wokukhanya we-ASE wokukhishwa okuzenzakalelayo kwefayibha efakwe i-erbium ungokulandelayo:
