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 luhambisana nenqubo yokumuncwa kokukhanya.Ushintsho olusuka ezingeni eliphezulu lamandla ukuya kwelamandla aphansi luhambisana nenqubo yokukhipha ukukhanya.
2. Umgomo we-EDFA
I-EDFA isebenzisa i-erbium ion-doped fiber njengendlela yokuzuza, ekhiqiza ukuguquguquka kwabantu ngaphansi kokukhanya kwepompo.Ibona ukukhulisa imisebe evuselelwe ngaphansi kokufakwa kokukhanya kwesignali.
I-Erbium ions inamazinga 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 engeyona 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.
Uma isignali yokufaka amandla e-photon E=hf ilingana ngokunembile nomehluko wezinga lamandla phakathi kwe-E2 ne-E1, E2-E1=hf, izinhlayiya ezisesimweni sokumetastable zizoshintshela kusimo esiphansi esingu-E1 ngesimo semisebe evuselelwe.I-radiation kanye nokokufaka Ama-photons kusiginali afana nama-photon, ngaleyo ndlela akhulise ngokuphawulekayo inombolo yama-photons, okwenza isignali yokubona okokufaka ibe isignali ephumayo enamandla ku-erbium-doped fiber, ibona ukukhuliswa okuqondile kwesignali yokubona. .
2. Umdwebo wesistimu nesingeniso sedivayisi eyisisekelo
2.1.Umdwebo wohlelo lohlelo lwe-L-band optical fiber amplifier umi kanje:
2.2.Umdwebo wohlelo lwesistimu yomthombo wokukhanya we-ASE wokuphuma ngokuzenzekelayo kwe-erbium-doped fiber imi kanje:
