Te whanaketanga me te tūnga mākete o te reera whakarerekē (Wāhanga tuarua)

Te kaupapa mahi orēseri ka taea te whakarerekē

E toru pea ngā mātāpono mō te whakatutuki i te whakatikatika i ngā roangaru taiaho. Ko te nuingangā taiaho ka taea te whakarerekēwhakamahia ngā matū mahi he whānui ngā rārangi kanapa. He iti noa ngā mate o ngā kaiwhakaoho e hanga ana i te taiaho i runga i te whānuitanga roangaru tino whaiti. Nō reira, ko te tuatahi ko te whakarerekē i te roangaru o te taiaho mā te whakarerekē i te roangaru e rite ana ki te rohe mate iti o te kaiwhakaoho e ētahi huānga (pēnei i te kupenga). Ko te tuarua ko te neke i te taumata pūngao o te whakawhiti taiaho mā te whakarerekē i ētahi tawhā o waho (pēnei i te papa aukume, te pāmahana, me ētahi atu). Ko te tuatoru ko te whakamahi i ngā pānga kore-raina hei whakatutuki i te whakawhiti roangaru me te whakahāngai (tirohia ngā whatu kore-raina, te marara Raman whakaoho, te takirua auau whatu, te oscillation tawhā whatu). Ko ngā taiaho noa e pā ana ki te aratau whakahāngai tuatahi ko ngā taiaho tae, ngā taiaho chrysoberyl, ngā taiaho pokapū tae, ngā taiaho hau pēhanga-teitei ka taea te whakarerekē me ngā taiaho excimer ka taea te whakarerekē.

Mai i te tirohanga hangarau whakatinanatanga, ka wehea te hangarau whakahaere o te taiaho whakarerekē ki: te hangarau whakahaere o nāianei, te hangarau whakahaere pāmahana me te hangarau whakahaere miihini.
I roto i ēnei, ko te hangarau whakahaere hiko he whakatutuki i te whakatikatika roangaru mā te whakarerekē i te iahiko werohanga, me te tere whakatikatika taumata-NS, te whānui o te whānui whakatikatika, engari he iti te mana putanga, e hangai ana ki te hangarau whakahaere hiko, ko te SG-DBR (te kopaki tauira DBR) me te taiaho GCSR (te kopaki āwhina te hononga aronga whakamuri-whakaata tauira). Ka whakarerekē te hangarau whakahaere pāmahana i te roangaru putanga o te taiaho mā te whakarerekē i te taupū whakaata o te rohe hohe taiaho. He māmā te hangarau, engari he puhoi, ā, ka taea te whakarerekē me te whānui whaiti o te torutoru nm noa iho. Ko ngā mea matua e hangai ana ki te hangarau whakahaere pāmahana koReera DFB(urupare tohatoha) me te taiaho DBR (whakaata Bragg tohatoha). Ko te mana whakahaere miihini e hangai ana ki te hangarau MEMS (pūnaha hiko-mīhini iti) hei whakaoti i te kōwhiringa o te roangaru, me te whānui whānui ka taea te whakarite, me te mana putanga teitei. Ko ngā hanganga matua e hangai ana ki te hangarau whakahaere miihini ko te DFB (urupare tohatoha), te ECL (taiaho kōhao o waho) me te VCSEL (taiaho whakaputa mata kōhao poutū). Ka whakamāramahia te mea e whai ake nei mai i ēnei āhuatanga o te kaupapa o ngā taiaho ka taea te whakarerekē.

Taupānga whakawhitiwhiti kōrero whatu

Ko te taiaho whakarerekē he taputapu optoelectronic matua i roto i tētahi whakatupuranga hou o te pūnaha wehewehe roangaru matotoru me te whakawhiti photon i roto i te whatunga whatu-katoa. Mā tōna whakamahinga ka nui ake te kaha, te ngāwari me te tauine o te pūnaha tuku muka whatu, ā, kua tutuki hoki te whakarerekētanga tonu, āhua tonu rānei i roto i te whānuitanga roangaru whānui.
Kei te kaha te whakatairanga a ngā kamupene me ngā whare rangahau huri noa i te ao i te rangahau me te whanaketanga o ngā rēseri ka taea te whakarerekē, ā, kei te haere tonu ngā ahunga whakamua hou i tēnei mara. Kei te whakapai tonu te mahi a ngā rēseri ka taea te whakarerekē, ā, kei te whakaiti tonu te utu. I tēnei wā, e rua ngā wāhanga matua o ngā rēseri ka taea te whakarerekē: ngā rēseri ka taea te whakarerekē haurua-ira me ngā rēseri muka ka taea te whakarerekē.
Reera hiko-hauruaHe puna mārama nui tēnei i roto i te pūnaha whakawhitiwhiti whatu, he iti nei te rahi, he māmā, he pai te hurihanga, he penapena hiko, ā, he ngāwari hoki te whakauru i ngā hikohiko maramara kotahi ki ētahi atu taputapu. Ka taea te wehewehe ki te taiaho urupare tohatoha ka taea te whakarerekē, te taiaho whakaata Bragg tohatoha, te taiaho tuku mata kōhao poutū pūnaha mota iti me te taiaho haurua kōhao o waho.
Nā te whanaketanga o te taiaho muka whakarerekē hei reo whakanui me te whanaketanga o te taiaho haurua-irahiko hei pūtake papu, kua tino whakatairangahia te whanaketanga o ngā taiaho muka. Ko te taiaho whakarerekē e hangai ana ki te whānui whakanui 80nm o te muka kua tāpirihia, ā, ka tāpirihia te huānga tātari ki te koropiko hei whakahaere i te roangaru whakamahana me te whakatutuki i te whakarerekētanga roangaru.
He tino kaha te whanaketanga o te rēhia haurua-ira ka taea te whakarerekē i te ao, ā, he tino tere hoki te ahunga whakamua. I te mea ka tata haere ngā rēhia whakarerekē ki ngā rēhia roangaru pumau i runga i te utu me te mahi, ka nui haere tonu te whakamahinga i roto i ngā pūnaha whakawhitiwhiti kōrero, ā, ka whai wāhi nui ki ngā whatunga whatu katoa a meake nei.

Te tirohanga whanaketanga
He maha ngā momo taiaho ka taea te whakarerekē, e whakawhanakehia ana mā te whakauru atu i ngā tikanga whakarerekē roangaru i runga i ngā momo taiaho kotahi-roa, ā, kua tukuna ētahi taonga ki te mākete o te ao. Haunga te whanaketanga o ngā taiaho ka taea te whakarerekē whatu tonu, kua pūrongohia hoki ngā taiaho ka taea te whakarerekē me ētahi atu mahi whakauru, pērā i te taiaho ka taea te whakarerekē kua whakauruhia ki te maramara kotahi o VCSEL me te kaiwhakatikatika mimiti hiko, me te taiaho kua whakauruhia ki te whakaata Bragg kurupae tauira me te whakakaha whatu haurua-ira me te kaiwhakatikatika mimiti hiko.
Nā te mea he whānui te whakamahinga o te taiaho whakarerekē roangaru, ka taea te whakamahi i te taiaho whakarerekē o ngā hanganga rerekē ki ngā pūnaha rerekē, ā, he painga me he ngoikoretanga o ia pūnaha. Ka taea te whakamahi i te taiaho haurua-ā-waho hei pūtake mārama whakarerekē whānui i roto i ngā taputapu whakamātautau tika nā te mea he nui te mana putanga me te roangaru whakarerekē tonu. Mai i te tirohanga o te whakaurunga photon me te tūtaki ki te whatunga whatu-katoa ā muri ake nei, ko te DBR kurupae tauira, te DBR kurupae hanganga-rahi me ngā taiaho whakarerekē kua whakauruhia ki ngā modulators me ngā amplifiers he puna mārama whakarerekē pai pea mō Z.
He momo pūtake mārama whai hua anō hoki te rēseri whatu ka taea te whakarerekē me te kōhao o waho, he hanganga māmā, he whānui rārangi whaiti, ā, he ngāwari te hononga muka. Mēnā ka taea te whakauru i te modulator EA ki roto i te kōhao, ka taea hoki te whakamahi hei pūtake soliton whatu ka taea te whakarerekē tere. Hei tāpiri, kua nui te ahunga whakamua o ngā rēseri muka ka taea te whakarerekē i runga i ngā rēseri muka i ngā tau tata nei. E tika ana kia whakapai ake i te mahi a ngā rēseri ka taea te whakarerekē i roto i ngā pūtake mārama whakawhitiwhiti whatu, ā, ka piki haere te wāhanga mākete, me ngā tūmanako tono tino kanapa.
