Tikanga ine mō te whānui rārangi otaiaho auau kotahi
He maha ngā tikanga ine mō te whānui raina taiaho auau kotahi mai i te matotoru ki te matotoru, tae atu ki ō rātou horopaki me ngā āhuatanga hangarau e tika ana, kua whakarāpopototia penei:
1, Ine tika mā te ine āwhata (ine matawhānui, whānui raina ≥ taumata GHz)
Whakamahia he ine āwhata, he ine āwhata whatu rānei (OSA) hei whakatau mēnā he aratau roa kotahi, inehia te ōwehenga pehi aratau taha me te whānui raina aratau roa. Ko te taumira ine āwhata tikanga he tata ki te 0.1-0.01 nm (e rite ana ki te 0.1-10 GHz mō te infrared tata), ā, ka taea e te mahi teitei te tae ki te 1 pm, he mea tika anake mō te tirotiro tuatahi o te whānui raina whānui.rēseri.
2、 Matawai Fabry Perot (FP) etalon (whānui raina whaiti waenga)
He pai mō ngā taiaho he whāiti ake te whānui o te rārangi, he iti ake rānei te tawhiti aratau roa i te taumira ine matawhānui. I te wā e ine ana, me whakatau i runga i te ōwehenga o te whānui rārangi taiaho ki te whānui aratau kōhao FP: ina nui ake te whānui rārangi taiaho i te whānui aratau kōhao, ka taea te pānui tika; ina rite, me wetewete; ki te iti rawa atu i te wā, me whakakapi ki tētahi FP tino tika ake, me whakamahi rānei i te hangarau whakatauira taha mō te whakatau tata.
3, Heterodyne/Whakaroa Whaiaro Heterodyne me te Homodyne Whaiaro (Whānuitanga rārangi whaiti, awhe kHz~MHz)
Ina nui ake te taumira o te ine ira whatu i te reiti auau kotahi e ōrite ana te hononga, ka whakamahia te tikanga heterodyne (me te reiti tohutoro whānui raina tino whaiti e mōhiotia ana) me te tikanga heterodyne whaiaro/homodyne whaiaro whakaroa-wā (kaore he reiti tohutoro). Ko te taputapu he ine muka Mach Zehnder, he ine Michelson rānei, me te whakaroa wā o τ d_d (e whakatauhia ana e te rerekētanga o te roa muka) i waenga i ngā ringa e rua; Te honoKaiwhakahaere AOMKo te nekehanga auau he heterodyne-ake, kāore e hono ana he homodyne-ake. Ka taea e te AOM Modulator te neke i te auau patu mai i te DC hei whakaiti i te pokanoa auau-iti.
4. Ngā Whakatūpato:
4.1 Ka pāngia ngā muka whatu toronga roa e te wiri/te paheketanga pāmahana, ā, me whakapai ake te pumau o te ine whakawhiti;
4.2 Me taurite ngā hongere hiko e rua, ā,Whakakaha Whatu EDFAka taea te whakamahi i te ine whakawhiti maha-huringa mō te utu, te mowhiti muka rānei;
4.3 Ina tino whaiti te whānui o te rārangi, ka taea te pānui i te whānui o te rārangi o te 20 dB, kātahi ka taea te whakatau i te whānui o te rārangi o te 3 dB i runga i te āhua o te rārangi Lorentz;
4.4 Whakamahia he pūmana whakapōraruraru (PC) he whakaata hurihuri Faraday rānei (FRM) hei pehi i te memeha o te whakapōraruraru.
