Te ia o te whanaketanga orēseri whānui-rārangi whaiti
Ko te whanaketanga o te aratau urupare taiaho i roto i te taiaho whānui-rārangi whaiti ko te whanaketanga o te hanganga kōhao resonant taiaho. Kei raro nei, ka whakaatuhia e mātou ngā whirihoranga rerekē o ngā hangarau taiaho whānui-rārangi whaiti i roto i te raupapa whanaketanga o ngā resonator taiaho.

1. Whirihoranga kōhao matua kotahi. Ka taea te wehewehe i tēnei momo taiaho ki te kōhao rārangi (whirihoranga matarohia, hanganga māmā me te whai hua) me te kōhao porowhita (te wikitoria i te tahunga kōhao ā-wāhi me te whakamahi i te mara ngaru haere). Ko te kaiwhakaoho mowhiti kore-papatahi (NPRO) e whakahuatia ana i roto i te kaiwhakaoho mowhiti, he mara ngaru haere motuhake me te tino pumau.rēseriMai i te tirohanga o te roa o te kōhao, ka taea te wehewehe ki ngā kōhao poto (he ngāwari ki te whakatinana i te aratau SLM kotahi te roa, engari he whānui te rārangi ā-roto me te haruru nui) me ngā kōhao roa (he mea tūturuwhānui rārangi whaiti, engari he uauatanga hangarau te whakatinana i te mahi SLM).

2. Whirihoranga urupare kotahi o te kōhao o waho. E whakaarohia ana tēnei whirihoranga hei whakaoti rapanga o te wā taunekeneke poto o te photon me te uaua ki te whakakore i te tukunga ohorere i roto i te kōhao matua kotahi, mā te tātari me te whāngai i ngā photon mā roto i te kōhao o waho hei whakawhāiti i te whānui o te rārangi. Ko ngā hanganga tawhito o mua ko ngā kōhao o waho momo Littrow me Littman Metcalf e whakamahi ana i ngā whariki. Ko te uauatanga hangarau o tēnei whirihoranga kei roto i te taurite ā-wāhanga i waenga i te kōhao matua me te kōhao o waho.
3. E rua ngā whirihoranga kōhao matua kua whakauruhia i runga i ngā whariki Bragg:

Reera DFBwhirihoranga: Mā te whakakotahi i te hanganga Bragg me te rohe hohe me te whakauru i te rohe nekehanga ā-wāhanga, he nui ake te whakaurunga, te pumau me te whaihua, ā, ka whakapai ake i te nekehanga roangaru o te DBR. Ko te uauatanga hangarau kei roto i te tukatuka whatanga (pēnei i te tikanga epitaxial tuarua RGF-DFB me te whakairo mata SG-DFB o te semiconductor DFB).
Whirihoranga taiaho DBR: ka whakakapi i ngā whakaata tuku iho ki ngā hanganga Bragg ā-wā, he āhuatanga tātari, he ngāwari hoki ki te whakatinana i te SLM me ngā kōhao poto. E ai ki te reo whakanui, ka taea te wehewehe ki te DBR haurua-ira (me te hototahitanga tukanga pai) me te DBR muka (e whakawhirinaki ana ki te tukatuka muka me te hangarau tāpiri).

Hei whakawhāiti ake i te whānui o te kōhao poto o te kōhao matua (pērā i te DFB/DBR), ka whakamahia he hanganga kōhao waho whakakotahi. Kua whanake te āhua o te kōhao o waho me te whanaketanga o te hangarau:
Te kōhao o waho o te wāhi: ngā āhua matua o mua, tae atu ki te whatanga (Littrow/Littman) me ngā tātari whatu rerekē (pēnei i te paerewa FP).
Te kōhao o waho o te muka whatu: mā te whakamahi i ngā taputapu muka whatu katoa (pēnei i ngā ara iahiko muka whatu, ngā FBG, ngā kōhao muka whatu FP, me ētahi atu), ka kaha ake te whakaurunga me te kaha ārai-whakararuraru.
Te kōhao arataki o waho: Te tukatuka nano iti e ahu mai ana i ngā rauemi haurua-ira pērā i te Si me te Si3N4, kia pai ake ai, kia pumau ai hoki te pūnaha.

Hei whakamutunga, ka whakaurua e tēnei tuhinga te whirihoranga o ngā taiaho hurihuri optoelectronic, he momo urupare motuhake tēnei, pērā i te hangarau whakapūmau auau PDH. Mā te whakamahi i te urupare hiko kino hei raka i te auau taiaho ki tētahi pūtake tohutoro tino pumau, ka taea te whakatutuki i te pumau auau tino teitei. Heoi, he uaua te pūnaha, he utu nui, ā, he iti te ngāwari o te roangaru.
