I-L-band EDFA amplifier system technical scheme

1. I-Erbium-doped fiber
I-Erbium iyisici somhlaba esingavamile esinenombolo ye-athomu engu-68 kanye nesisindo se-athomu esingu-167.3. Izinga lamandla kagesi we-erbium ion liboniswa emfanekisweni, futhi uguquko olusuka ezingeni eliphansi lamandla ukuya ezingeni eliphezulu lamandla lihambisana nenqubo yokumuncwa kokukhanya. Ushintsho olusuka ezingeni eliphezulu lamandla ukuya kwelamandla aphansi luhambisana nenqubo yokukhipha ukukhanya.

I-EDFA isebenzisa i-erbium ion-doped fiber njengendlela yokuzuza, ekhiqiza ukuguquguquka kwabantu ngaphansi kokukhanya kwepompo. Ibona ukukhulisa imisebe evuselelwe ngaphansi kokufakwa kokukhanya kwesignali.
Ama-Erbium ions anamazinga amathathu wamandla. Zisezingeni eliphansi lamandla, i-E1, lapho zingajatshuliswa noma yikuphi ukukhanya. Uma i-fiber ijatshuliswa ngokuqhubekayo i-laser yomthombo wokukhanya wepompo, izinhlayiya ezisesimweni esiphansi zithola amandla futhi zishintshele ezingeni eliphezulu lamandla. Njengoguquko olusuka ku-E1 luye ku-E3, ngenxa yokuthi i-particle ayizinzile ezingeni eliphezulu lamandla e-E3, izowela ngokushesha esimweni se-metastable E2 ngenqubo yoguquko olungenayo imisebe. Kuleli zinga lamandla, izinhlayiya ziphila isikhathi eside uma kuqhathaniswa. Ngenxa yenjabulo eqhubekayo yomthombo wokukhanya wepompo, inani lezinhlayiya ezingeni le-E2 lamandla lizoqhubeka nokukhula, futhi inani lezinhlayiya ezingeni le-E1 lamandla lizokhula. Ngale ndlela, ukusatshalaliswa kokuguqulwa kwabantu kutholwa ku-erbium-doped fiber, futhi izimo zokufunda ukukhuliswa kwe-optical ziyatholakala.
Lapho isignali yokufaka amandla e-photon E=hf ilingana ngokunembile nomehluko wezinga lamandla phakathi kwe-E2 ne-E1, E2-E1=hf, izinhlayiya ezisesimweni sokumetastable zizoshintshela esimweni esiphansi esingu-E1 ngesimo semisebe evuselelwe. I-radiation kanye nokokufaka Ama-photon akusiginali afana nama-photon, ngaleyo ndlela akhulise ngokuphawulekayo inombolo yama-photons, okwenza isignali yokubona okokufaka ibe isignali yokuphuma enamandla ku-erbium-doped fiber, ibona ukukhuliswa okuqondile kwesignali yokubona. .
