Te tūranga o te kiriata angiangi o te lithium niobate i roto i te modulator electro-optic

Te tūranga o te kiriata angiangi o te lithium niobate i roto ikaiwhakarerekē hiko-whatu
Mai i te tīmatanga o te umanga ki nāianei, kua piki ake te kaha o te whakawhitiwhiti kōrero muka-kotahi ki ngā miriona wā, ā, kua neke atu i te tekau miriona wā te maha o ngā rangahau hou. He mahi nui tā te lithium niobate i waenganui i tā mātou umanga. I ngā rā tōmua o te whakawhitiwhiti kōrero muka whatu, i whakatikatika tikahia te whakarerekētanga o te tohu whatu ki runga i terēseriE whakaaetia ana tēnei momo whakarerekētanga i roto i ngā tono iti te whānui o te hononga, i ngā tono tawhiti poto rānei. Mō ngā tono whakarerekētanga tere-tiketike me ngā tono tawhiti-roa, kāore e ranea te whānui o te hononga, ā, he nui rawa te utu o te hongere tuku hei whakatutuki i ngā tono tawhiti-roa.
I waenganui i te whakawhitiwhiti kōrero muka whatu, ka tere haere te whakarerekētanga tohu hei whakatutuki i te pikinga o te kaha whakawhitiwhiti kōrero, ā, ka tīmata te wehewehe i te aratau whakarerekētanga tohu whatu, ā, ka whakamahia ngā momo whakarerekētanga rerekē i roto i te whatunga tawhiti-poto me te whatunga pūrua tawhiti-roa. Ka whakamahia te whakarerekētanga tika iti-utu i roto i te whatunga tawhiti-poto, ā, ka whakamahia he "whakarerekētanga hiko-whatu" motuhake i roto i te whatunga pūrua tawhiti-roa, e wehea ana mai i te taiaho.
Ka whakamahia e te kaiwhakatikatika hiko-whatu te hanganga whakararuraru Machzender hei whakarerekē i te tohu, he ngaru hikohiko te mārama, ā, me whakahaere pūmau te auau, te āhua me te pōraruraru o te whakararuraru pumau o te ngaru hikohiko. He maha ā tātou kōrero mō te kupu, e kiia nei ko ngā tawhā whakararuraru, ko ngā tawhā mārama me te pōuri, ko te kanapa te wāhi e whakanuia ana te whakararuraru hikohiko, ko te pōuri te wāhi e ngoikore ai te kaha o te whakararuraru hikohiko. Ko te whakararuraru Mahzender he momo ine whakawhiti me te hanganga motuhake, ko te pānga whakararuraru e whakahaeretia ana mā te whakahaere i te āhua o te hihi kotahi i muri i te wehenga o te hihi. Arā, ka taea te whakahaere i te hua whakararuraru mā te whakahaere i te āhua whakararuraru.
Ko te lithium niobate tēnei rauemi e whakamahia ana i roto i te whakawhitiwhiti muka whatu, arā, ka taea e ia te whakamahi i te taumata ngaohiko (tohu hiko) hei whakahaere i te āhua o te mārama, hei whakatutuki i te whakarerekētanga o te tohu mārama, koinei te whanaungatanga i waenga i te modulator hiko-whatu me te lithium niobate. Ko tā mātou modulator e kiia nei he modulator hiko-whatu, me whai whakaaro ki te pono o te tohu hiko me te kounga whakarerekētanga o te tohu whatu. He pai ake te kaha tohu hiko o te indium phosphide me te silicon photonics i te lithium niobate, ā, he ngoikore ake te kaha tohu whatu engari ka taea hoki te whakamahi, ka hangaia he huarahi hou hei hopu i te whai wāhitanga mākete.
Haunga ō rātou āhuatanga hiko tino pai, he pai ngā painga o te whakawhāiti me te whakauru o te indium phosphide me te silicon photonics kāore i te lithium niobate. He iti ake te indium phosphide i te lithium niobate, ā, he teitei ake te tohu whakauru, ā, he iti ake ngā photon silicon i te indium phosphide, ā, he teitei ake te tohu whakauru. Ko te pane o te lithium niobate heikaiwhakarerekēe rua te roa ake i te indium phosphide, ā, he modulator anake, kāore e taea te whakauru i ētahi atu mahi.
I tēnei wā, kua uru te pūwhakatikatika hiko-whatu ki te wā o te tere tohu 100 piriona, (ko te 128G he 128 piriona), ā, kua tīmata anō te pakanga a te lithium niobate ki te whai wāhi atu ki te whakataetae, me te tumanako ka ārahi i tēnei wā a mua tata nei, ka ārahi i te urunga atu ki te mākete tere tohu 250 piriona. Kia taea ai e te lithium niobate te whakahoki mai i tēnei mākete, me tātari he aha ngā mea kei roto i te indium phosphide me te silicon photons, engari kāore i roto i te lithium niobate. Koinā te kaha hiko, te whakaurunga teitei, te whakaitiiti.
E toru ngā koki e rerekē ai te lithium niobate, ko te koki tuatahi me pēhea te whakapai ake i te kaha hiko, ko te koki tuarua me pēhea te whakapai ake i te whakaurunga, ā, ko te koki tuatoru me pēhea te whakaiti. Kotahi noa te mahi e hiahiatia ana mō te otinga o ēnei koki hangarau e toru, arā, te whakaangawari i te rauemi lithium niobate, te tango i tētahi paparanga angiangi rawa o te rauemi lithium niobate hei arataki whatu, ka taea te hanga anō i te hikohiko, te whakapai ake i te kaha hiko, te whakapai ake i te whānui me te whai huatanga o te tohu hiko. Whakapai ake i te kaha hiko. Ka taea hoki te tāpiri i tēnei kiriata ki te anga silicon, hei whakatutuki i te whakaurunga whakauru, ko te lithium niobate hei kaiwhakahaere, ko te toenga o te whakaurunga photon silicon, he mārama ki te katoa te kaha whakaiti photon silicon, ko te kiriata lithium niobate me te whakaurunga marama silicon, hei whakapai ake i te whakaurunga, ka tutuki te whakaiti maori.
I roto i ngā rā kei te heke mai, ka tata te whakaurunga hiko-whatu ki te wā o te tere tohu 200 piriona, kei te kitea haere te ngoikoretanga whatu o te indium phosphide me te silicon photons, ā, kei te kitea haere te painga whatu o te lithium niobate, ā, ka whakapai ake te kiriata angiangi lithium niobate i te ngoikoretanga o tēnei rauemi hei whakaurunga, ā, ka arotahi te umanga ki tēnei "kiriata angiangi lithium niobate", arā, te kiriata angiangi.te kaiwhakatikatika lithium niobateKoinei te mahi a te niobate lithium kiriata angiangi i roto i te mara o ngā whakarerekētanga hiko-whatu.
