Ngā whakakaha whatu i roto i te mara o te whakawhitiwhiti muka whatu
An whakakaha whatuHe taputapu e whakanui ana i ngā tohu whatu. I roto i te ao whakawhitiwhiti muka whatu, ko āna mahi matua e whai ake nei: 1. Te whakarei ake me te whakanui i te mana whatu. Mā te whakanoho i te whakanui whatu ki te pito o mua o te tuku whatu, ka taea te whakanui ake i te mana whatu e uru ana ki te muka. 2. Te whakanui i te tuku ipurangi, hei whakakapi i ngā Whakahoki o nāianei i roto i ngā pūnaha whakawhitiwhiti muka whatu; 3. Te whakanui mua: I mua i te kite whakaahua i te pito whiwhi, ka whakanuia mua te tohu mārama ngoikore hei whakanui ake i te aro o te whiwhi.
I tēnei wā, ko ngā momo whakakaha whatu e whakamahia ana i roto i te whakawhitiwhiti muka whatu ko ēnei: 1. Whakakaha whatu haurua-whakahaere (Whakakaha whatu SOA)/Whakakaha taiaho hiko-haurua (whakakaha whatu SLA); 2. Ngā whakakaha muka kua tāpirihia ki te whenua onge, pērā i ngā whakakaha muka kua tāpirihia ki te maunu (Whakakaha whatu EDFA), me ētahi atu. 3. Ngā whakakaha muka kore-raina, pērā i ngā whakakaha muka Raman, me ētahi atu. He kupu whakataki poto tēnei e whai ake nei.
1. Ngā whakakaha whatu haurua-ārahi: I raro i ngā āhuatanga tono rerekē, me te whakaata rerekē o te mata pito, ka taea e ngā reera haurua-ārahi te whakaputa i ngā momo whakakaha whatu haurua-ārahi. Mena he iti iho te ia taraiwa o te reera haurua-ārahi i tōna paepae, arā, kāore he reera e puta, i tēnei wā, ka whakaurua he tohu whatu ki tētahi pito. Mena kei te tata te auau o tēnei tohu whatu ki te pokapū hihi o te reera, ka whakakahangia, ka puta mai i tētahi atu pito. Ko tēnei momowhakakaha whatu haurua-hauruae kiia ana ko te whakakaha whatu momo Fabry-Perrop (FP-SLA). Mena kei runga ake te rēseri i te paepae, ka uru mai te tohu whatu aratau-kotahi ngoikore mai i tetahi pito, mena kei roto te auau o tēnei tohu whatu i te whānuitanga o tēnei rēseri maha-aratau, ka whakanuia te tohu whatu, ka raka ki tētahi aratau. Ka kiia tēnei momo whakakaha whatu ko te whakakaha momo raka-whakauru (IL-SLA). Mena ka pania ngā pito e rua o te rēseri haurua-waenga, ka mimitia rānei ki tētahi paparanga kiriata ārai-whakaata, ka iti rawa te putanga, ā, kāore e taea te hanga i tētahi kōhao whakakoi Fabry-Perrow, ina haere te tohu whatu mā te paparanga arataki ngaru hohe, ka whakanuia i a ia e haere ana. Nō reira, ka kiia tēnei momo whakakaha whatu ko te whakakaha whatu momo ngaru haere (TW-SLA), ā, e whakaaturia ana tōna hanganga i te pikitia e whai ake nei. Nā te mea e toru ngā whakarea te rahi o te whānui o te whakakaha whatu momo ngaru haere i tō te whakakaha momo Fabry-Perot, ā, ka taea e tōna whānui 3dB te eke ki te 10THz, ka taea e ia te whakakaha i ngā tohu whatu o ngā auau rerekē, ā, he whakakaha whatu tino whai hua.
2. Whakakaha muka i whakakīia ki te mōunu: E toru ngā wāhanga: Ko te tuatahi he muka i whakakīia, he roa mai i ētahi mita ki ngā tekau mita. Ko ēnei poke he katote whenua onge te nuinga, e hanga ana i te rauemi whakahohe laser; Ko te tuarua ko te pūtake papu laser, e whakarato ana i te kaha o ngā roangaru e tika ana hei whakaoho i ngā katote whenua onge kua whakakīia kia tutuki ai te whakanui i te mārama. Ko te tuatoru ko te hononga, e āhei ai te mārama papu me te mārama tohu ki te hono ki roto i te rauemi whakahohe muka whatu kua whakakīia. He tino rite te kaupapa mahi o te whakakaha muka ki te laser āhua totoka. Ka puta he āhua tohatoha tau matūriki kua hurihia i roto i te rauemi whakahohe laser, ā, ka whakaputa i te ira whakaoho. Hei waihanga i tētahi āhua tohatoha hurihanga tau matūriki pumau, me neke atu i te rua ngā taumata kaha e uru ana ki te whakawhiti whatu, ko te tikanga he pūnaha taumata-toru me te taumata-whā, me te tuku tonu i te kaha mai i te pūtake papu. Hei whakarato kaha whai hua, me poto ake te roangaru o te photon papu i te photon laser, arā, me nui ake te kaha o te photon papu i te photon laser. Hei tāpiritanga, ka hangaia he urupare pai e te kōhao haruru, ā, nō reira ka taea te hanga i tētahi whakakaha taiaho.
3. Ngā whakakaha muka kore-raina: Kei raro i te kāwai whakakaha muka ngā whakakaha muka kore-raina me ngā whakakaha muka erbium. Heoi, ko te tuatahi e whakamahi ana i te pānga kore-raina o ngā muka kuata, ko te tuarua ia e whakamahi ana i ngā muka kuata kua tāpirihia ki te erbium hei mahi i runga i ngā pāpāho hohe. Ka whakaputa ngā muka whatu kuata noa i ngā pānga kore-raina kaha i raro i te mahi a te mārama papu kaha o ngā roangaru e tika ana, pērā i te marara Raman whakaohooho (SRS), te marara Brillouin whakaohooho (SBS), me ngā pānga whakaranu ngaru-whā. Ina tukuna te tohu i te taha o te muka whatu me te mārama papu, ka taea te whakakaha i te mārama tohu. Nō reira, ka hangaia e rātou ngā whakakaha muka Raman (FRA), ngā whakakaha Brillouin (FBA), me ngā whakakaha tawhā, he whakakaha muka tohatoha katoa ēnei.
Whakarāpopototanga: Ko te ahunga whanaketanga noa o ngā whakakaha whatu katoa he nui te whakanui, he nui te mana putanga, me te iti o te haruru.
