L-band EDFA ampliifier system kaupapa hangarau

1. Erbium-doped muka
He huānga whenua onge te Erbium me te tau ngota 68 me te taumaha ngota 167.3. Ko te taumata hiko hiko o te katote erbium e whakaatuhia ana i roto i te ahua, a ko te whakawhiti mai i te taumata hiko o raro ki te taumata hiko o runga e rite ana ki te tukanga absorption o te marama. Ko te huringa mai i te taumata kaha o runga ki te taumata o raro o te kaha e rite ana ki te tukanga tuku marama.

2. Tikanga EDFA

p2

Ka whakamahia e te EDFA te muka erbium katote-doped hei taputapu taonga, ka puta te hurihanga taupori i raro i te rama papu. Ka mohio ia ki te whakanui i te hihi iraruke i raro i te whakaurunga o te rama tohu.
E toru nga taumata kaha o nga katote Erbium. Kei te taumata iti rawa o te kaha, E1, i te mea karekau ratou e hikaka ki tetahi rama. I te wa e hikaka tonu ana te muka e te taiaho puna marama papu, ka whiwhi nga matūriki o te whenua i te kaha me te whakawhiti ki te taumata kaha ake. Pērā i te whakawhiti mai i te E1 ki te E3, na te mea ko te matūriki e kore e mau i te taumata teitei o te kaha o E3, ka tere te taka ki te ahua metastable E2 i roto i te tukanga whakawhiti kore-radiative. I tenei taumata kaha, he roa te oranga o nga matūriki. Na te whakaoho tonu o te puna marama papu, ka piki tonu te maha o nga matūriki i te taumata kaha E2, ka piki ake te maha o nga matūriki i te taumata kaha E1. Ma tenei ara, ka kitea te tohatoha hurihanga taupori i roto i te muka erbium-doped, a kei te waatea nga tikanga mo te ako whakakaha whatu.
I te wa e rite ana te tohu whakaurunga hiko whakaahua E=hf ki te rereketanga o te taumata o te kaha i waenga i te E2 me te E1, E2-E1=hf, ka huri nga matūriki o te ahua metastable ki te whenua whenua E1 i te ahua o te iraruke whakahihiko. Te iraruke me te whakauru Ko nga whakaahua kei roto i te tohu he rite tonu ki nga whakaahua, na reira ka tino piki ake te maha o nga whakaahua, na te mea ka riro te tohu whatu whakauru hei tohu whakaputa kaha i roto i te muka erbium-doped, me te mohio ki te whakanui tika o te tohu whatu. .
