Nā te nui o te whānui o te hononga me te iti o te whakaiti i te tere o te whatunga e hua mai ana i te muka whatu, kei te tere haere te tere o te whatunga. Kei te tere haere hoki te whanaketanga o te hangarau whakawhiti muka whatu hei whakatutuki i ngā hiahia e piki haere tonu ana mō te tere me te kaha. Me titiro tātou ki te pānga o tēnei whanaketanga ki ngā pokapū raraunga.
He mukawhakawhiti whatuhe ara iahiko whakauru (IC) ka taea te tuku me te whiwhi raraunga motuhake i ngā taha e rua. Ka whakakotahi te taputapu i te tuku me te kaiwhiwhi ki roto i te kōwae kotahi e huri ana i ngā tohu hiko ki ngā tohu whatu, ka taea ai te tuku pai i ēnei tohu mai i te tūmau ki te tūmau mā roto i ngā taura muka whatu.
Te ngā kaiwhakawhiti whakawhitite whakaurunga hiko ki te putanga whatu mai i te diode taiaho, i te pūtake rama LED rānei (ka honoa te rama ki te muka whatu mā te hononga, ā, ka tukuna mā te taura muka whatu). Ka honoa te rama mai i te pito o te muka ki te kaiwhiwhi, ā, ka hurihia te rama e te pūoko hei tohu hiko, ka whakaritea kia whakamahia e te taputapu kaiwhiwhi. He aha kei roto i te tuku whakawhiti muka whatu?
Ko ngā whakawhiti muka whatu he mea hanga mai i ngā whakawhiti, ngā kaiwhiwhi, ngā taputapu whatu me ngā maramara. Ko te maramara te ngākau o te waeine muka whatu. I ngā tau tata nei, kua piki haere te hiahia ki te whakamahi i ngā hihi-whakaata silicon i roto i ngā maramara whakawhiti - te hanga i ngā taiaho ki runga i te silicon, kātahi ka hono i ngā wāhanga whatu me ngā ara iahiko whakauru silicon. Ka aro atu ki te hiahia mō ngā hononga tere ake mai i te whatanga ki te whatanga, puta noa i ngā pokapū raraunga. Ka whakangawari ake i te tukanga huihuinga. Hei tāpiri, ka taea te hanga i ngā whakawhiti kiato ake, ka whakaiti i te tapuwae tūmau whānui, ka taea ai ngā pokapū raraunga iti ake, kia kikokore ake, me te pupuri tonu i te kiato tauranga teitei. I tētahi atu taha, ko te rahi iti ake te tikanga he iti ake te whakamahinga hiko me te iti ake o te utu.
He Hītori Poto o ngā Whakawhitiwhiti Whatu
Ko te whakaurunga o te hangarau silicon photonics ki roto i ngā maramara whakawhiti raraunga he tohu tēnei i te whanaketanga nui o te hangarau whakawhiti raraunga muka-whatu. Ko te ia o ngā ia whakawhiti raraunga muka whatu kei te neke haere ki ngā rahi iti ake me ngā tere raraunga teitei ake hei whakatutuki i te pikinga o te rere raraunga i puta mai i te hurihanga Ipurangi.
