Te heke mai ongā whakarerekētanga whatu hiko
He mahi nui tā ngā pūwhakatikatika whatu hiko i roto i ngā pūnaha optoelectronic hou, he mahi nui tā rātou i roto i ngā mara maha mai i te whakawhitiwhiti kōrero ki te rorohiko matū mā te whakahaere i ngā āhuatanga o te mārama. E matapakihia ana e tēnei pepa te āhua o nāianei, ngā putanga hou me te whanaketanga ā muri ake nei o te hangarau pūwhakatikatika whatu hiko.
Pikitia 1: Te whakataurite i te mahi o ngā momo rerekēpūwhakarerekē whatungā hangarau, tae atu ki te lithium niobate kiriata angiangi (TFLN), ngā kaiwhakatikatika mimiti hiko III-V (EAM), ngā kaiwhakatikatika hanga-silicon me ngā kaiwhakatikatika polymer e pā ana ki te ngaronga whakaurunga, te whānui o te hononga, te kai hiko, te rahi, me te kaha hanga.
Ngā whakarerekētanga whatu hiko tuku iho e hangai ana ki te silicon me ō rātou herenga
Ko ngā pūwhakatikatika mārama hiko-whakaahua e ahu mai ana i te silicon te pūtake o ngā pūnaha whakawhitiwhiti kōrero whatu mō ngā tau maha. I runga i te pānga marara o te plasma, kua tino angitu aua taputapu i roto i ngā tau 25 kua hipa, kua piki ake ngā tere whakawhiti raraunga e toru ngā whakarea o te kaha. Ka taea e ngā pūwhakatikatika e ahu mai ana i te silicon hou te whakatutuki i te whakatikatika kaha pāoro 4-taumata (PAM4) tae atu ki te 224 Gb/s, ā, neke atu i te 300 Gb/s me te whakatikatika PAM8.
Heoi, kei te pāngia ngā kaiwhakatikatika e ahu mai ana i te silicon e ngā herenga taketake e ahu mai ana i ngā āhuatanga o te rauemi. Ina hiahiatia e ngā transceiver whatu he tere baud neke atu i te 200+ Gbaud, he uaua ki te whakatutuki i te hiahia o te whānui o te whānui o ēnei taputapu. I ahu mai tēnei herenga i ngā āhuatanga tūturu o te silicon – ko te taurite o te karo i te ngaronga mārama nui me te pupuri tonu i te kawe hiko e hanga ana i ngā taupatupatu e kore e taea te karo.
Ngā hangarau me ngā rauemi whakarerekētanga hou
Nā ngā herenga o ngā pūwhakatikatika tuku iho e hangai ana ki te silicon kua akiaki i te rangahau ki ngā rauemi rerekē me ngā hangarau whakauru. Kua noho te niobate lithium kiriata angiangi hei tētahi o ngā tūāpapa tino whai hua mō tētahi whakatupuranga hou o ngā pūwhakatikatika.Ngā whakarerekētanga hiko-whatu lithium niobate kiriata angiangiKa riro i a ia ngā āhuatanga tino pai o te niobate lithium papatipu, tae atu ki: te matapihi whānui mārama, te tauwehenga hiko-whatu nui (r33 = 31 pm/V) te pūtau raina Ka taea e te pānga Kerrs te mahi i roto i ngā awhe roangaru maha
Kua puta he hua whakamiharo i ngā whanaketanga hou o te hangarau lithium niobate kiriata angiangi, tae atu ki tētahi modulator e mahi ana i te 260 Gbaud me ngā tere raraunga o te 1.96 Tb/s mō ia hongere. He painga ahurei tō te tūāpapa pēnei i te ngaohiko taraiwa hototahi ki te CMOS me te whānui o te 3-dB o te 100 GHz.
Te tono hangarau hou
He hononga tata te whanaketanga o ngā pūwhakatikatika hiko whatu ki ngā tono hou i roto i ngā mara maha. I roto i te mara o te matauranga horihori me ngā pokapū raraunga,ngā kaiwhakarerekē tere-teiteihe mea nui mō te whakatupuranga o ngā hononga e whai ake nei, ā, ko ngā tono rorohiko AI kei te akiaki i te hiahia mō ngā transceiver mono 800G me te 1.6T. Ka whakamahia hoki te hangarau modulator ki: te tukatuka mōhiohio kuantum te rorohiko neuromorphic te ngaru tonu te ngaru auau (FMCW) te hangarau photon ngaruiti lidar
Ina koa, he kaha ngā whakarerekētanga hiko-whatu o te lithium niobate kiriata angiangi i roto i ngā miihini tukatuka rorohiko whatu, e whakarato ana i te whakarerekētanga tere iti-mana e tere ake ai te ako mīhini me ngā tono matauranga horihori. Ka taea hoki e ēnei whakarerekētanga te mahi i ngā pāmahana iti, ā, he pai mō ngā atanga matatini-kuantum i roto i ngā raina superconducting.
He maha ngā wero nui e pā ana ki te whanaketanga o ngā pūwhakarerekē hiko whatu o te whakatupuranga e whai ake nei: Te utu whakaputa me te tauine: ko ngā pūwhakarerekē lithium niobate kiriata-angiangi e whakawhāitihia ana ki te hanga wafer 150 mm, ka hua ake he utu nui ake. Me whakawhānui te umanga i te rahi wafer me te pupuri tonu i te ōritetanga me te kounga o te kiriata. Te Whakaurunga me te Hoahoa-tahi: Ko te whanaketanga angitu ongā kaiwhakarerekētanga mahi-teiteime whai pūkenga hoahoa tahi whānui, me uru atu te mahi tahi a ngā kaihoahoa hikohiko me ngā kaihoahoa maramara hiko, ngā kaiwhakarato EDA, ngā puna, me ngā tohunga tākai. Te uaua o te hanga: Ahakoa he iti ake te uaua o ngā tukanga hikohiko e hangai ana ki te silicon i ngā hikohiko CMOS matatau, me nui te tohungatanga me te arotau i ngā tukanga hanga ki te whakatutuki i te mahi pumau me te hua.
Nā te puāwaitanga o te hangarau mohio me ngā āhuatanga tōrangapū, kei te piki haere te haumitanga mai i ngā kāwanatanga, ngā umanga me te rāngai tūmataiti huri noa i te ao ki tēnei mara, e hanga ana i ngā whai wāhitanga hou mō te mahi tahi i waenga i te ao mātauranga me te umanga, me te oati hoki ki te whakateretere i te auahatanga.
