Te hangarau hikohangarau whakawhitiwhiti raraunga
I roto i ētahi kāwai ongā taputapu whakaahua, he whakataetae ngā wāhanga photonic silicon ki ngā taputapu pai rawa atu o te karaehe, e kōrerohia ana i raro nei. Akene ko tā mātou e whakaaro nei ko te mahi tino whakarerekētanga i roto ingā whakawhitiwhiti kōrero whatuKo te hanganga o ngā tūāpapa whakauru e whakauru ana i ngā pūwhakatikatika, ngā pūoko, ngā arataki ngaru, me ētahi atu wāhanga i runga i te maramara kotahi e whakawhitiwhiti kōrero ana tetahi ki tetahi. I ētahi wā, ka whakaurua hoki ngā transistors ki roto i ēnei tūāpapa, e āhei ai te whakauru i te whakakaha, te raupapatanga, me te urupare ki runga i te maramara kotahi. Nā te utu o te whakawhanake i aua tukanga, ko te kaupapa matua o tēnei mahi ko ngā tono mō te whakawhitiwhiti raraunga hoa-ki-hoa. Ā, nā te utu o te whakawhanake i tētahi tukanga hanga transistor, ko te whakaaro whānui e puta ake ana i te mara, mai i te tirohanga mahi me te utu, he mea tino tika mō ngā rā kei te heke mai ki te whakauru i ngā taputapu hiko mā te mahi i te hangarau hononga i te taumata wafer, i te taumata maramara rānei.
He mea nui te kaha ki te hanga maramara ka taea te tatau mā te whakamahi i ngā taputapu hiko me te whakawhitiwhiti kōrero whatu. Ko te nuinga o ngā whakamahinga tōmua o te photonics silicon i roto i ngā whakawhitiwhiti raraunga mamati. Nā ngā rerekētanga ā-tinana taketake i waenga i ngā irahiko (fermion) me ngā photon (bosons) tēnei i ārahi. He pai ngā irahiko mō te rorohiko nā te mea kāore e taea e rāua te noho i te wāhi kotahi i te wā kotahi. Ko te tikanga o tēnei he kaha te taunekeneke a rāua tetahi ki tetahi. Nō reira, ka taea te whakamahi i ngā irahiko ki te hanga i ngā taputapu whakawhiti kore-raina nui - ngā transistors.
He rerekē ngā āhuatanga o ngā photon: he maha ngā photon ka taea te noho ki te wāhi kotahi i te wā kotahi, ā, i raro i ngā āhuatanga tino motuhake, kāore rātou e pokanoa tetahi ki tetahi. Koia te take e taea ai te tuku tiriona o ngā moka raraunga ia hekona mā te muka kotahi: kāore e taea mā te waihanga i tētahi awa raraunga me te whānui terabit kotahi.
I ngā wāhi maha o te ao, ko te muka ki te kāinga te tauira urunga matua, ahakoa kāore anō kia whakamātauhia tēnei i te United States, e whakataetae ana ki te DSL me ētahi atu hangarau. I te mea kei te piki haere tonu te hiahia mō te whānui o te raraunga, kei te piki haere tonu te hiahia ki te akiaki i te tuku raraunga pai ake mā te muka whatu. Ko te ia whānui i roto i te mākete whakawhitiwhiti raraunga ko te mea ka heke te tawhiti, ka heke nui te utu o ia wāhanga i te mea ka piki ake te rahinga. Ehara i te mea miharo, kua arotahi ngā mahi hokohoko o te silicon photonics ki te nui o te mahi ki ngā tono nui-rahi, poto-whānui, e aro ana ki ngā pokapū raraunga me te rorohiko mahi-teitei. Ko ngā tono ā muri ake nei ka uru atu ki te hononga papa-ki-papa, te hononga poto-whānui USB, me te whakawhitiwhiti matua-ki-matua pea i te mutunga, ahakoa he whakaaro noa iho te mea ka tupu me ngā tono matua-ki-matua i runga i te maramara. Ahakoa kāore anō kia eke ki te tauine o te umanga CMOS, kua tīmata te silicon photonics ki te noho hei umanga nui.
