Pūwhakarerekētanga hiko-whatu mahi teitei:kaiwhakarerekētanga kiriata angiangi lithium niobate
He whakarerekētanga hiko-whatu (Kaiwhakatikatika EOM) he pūwhakarerekētanga i hangaia mā te whakamahi i te pānga hiko-whatu o ētahi tioata hiko-whatu, ka taea te huri i ngā tohu hiko tere-teitei i roto i ngā taputapu whakawhitiwhiti kōrero hei tohu whatu. Ina tukuna te tioata hiko-whatu ki tētahi mara hiko kua whakamahia, ka huri te taupū whakaata o te tioata hiko-whatu, ā, ka huri anō hoki ngā āhuatanga ngaru whatu o te tioata, kia tutuki ai te whakarerekētanga o te kaha, te āhua o te wāhanga me te āhua pōraritanga o te tohu whatu, me te huri i te tohu hiko tere-teitei i roto i te taputapu whakawhitiwhiti kōrero hei tohu whatu mā te whakarerekētanga.
I tēnei wā, e toru ngā momo matua ongā kaiwhakatikatika hiko-whatukei te mākete: ngā kaiwhakarerekētanga e hangai ana ki te silicon, ngā kaiwhakarerekētanga indium phosphide me te kiriata angiangite kaiwhakatikatika lithium niobateI roto i ēnei, kāore he tauwehenga hiko-whatu tika o te silicon, he whānui ake te mahi, he pai anake mō te hanga i te waeine whakawhiti raraunga tawhiti-poto, ahakoa he pai te indium phosphide mō te waeine whakawhiti whatunga whakawhitiwhiti whatu tawhiti-waenga, engari he tino teitei ngā whakaritenga tukanga whakauru, he tino teitei te utu, ā, he iti noa ngā herenga o te tono. He rerekē, ehara i te mea he nui noa te pānga whakaahua-hiko o te tioata lithium niobate, engari he rite tonu te pānga whakaahua-whakaata, te pānga kore-raina, te pānga hiko-whatu, te pānga whatu oro, te pānga piezoelectric me te pānga thermoelectric ki te kotahi, ā, nā tōna hanganga whatunga me tōna hanganga hapa nui, he maha ngā āhuatanga o te lithium niobate ka taea te whakahaere nui mā te hanganga tioata, te tāpiritanga huānga, te whakahaere āhua valence, me ētahi atu. Ka tutuki te mahi whakaahua-hiko pai rawa atu, pērā i te tauwehenga hiko-whatu tae atu ki te 30.9pm/V, he nui ake i te indium phosphide, ā, he iti te pānga chirp (pānga chirp: e pā ana ki te āhuatanga e huri ana te auau i roto i te pātere i te wā e tukuna ana te pātere laser. Ko te pānga chirp nui ake ka hua ake he ōwehenga tohu-ki-haruru iti me te pānga kore-raina), he ōwehenga mate pai (te ōwehenga mana toharite o te āhua "ki runga" o te tohu ki tōna āhua "weto"), me te pumau taputapu pai ake. Hei tāpiritanga, he rerekē te tikanga mahi a te kaiwhakatikatika lithium niobate kiriata angiangi i tērā o te kaiwhakatikatika e hangai ana ki te silicon me te kaiwhakatikatika indium phosphide e whakamahi ana i ngā tikanga whakarerekētanga kore-raina, e whakamahi ana i te pānga hiko-whatu raina hei uta i te tohu whakarerekētanga hiko ki runga i te kawe whatu, ā, ko te tere whakarerekētanga e whakatauhia ana e te mahi a te irahiko ngaruiti, kia taea ai te whakatutuki i te tere whakarerekētanga teitei me te raina me te iti o te kai hiko. I runga i ngā mea o runga ake nei, kua waiho te lithium niobate hei whiringa pai mō te whakarite i ngā kaiwhakatikatika hiko-whatu mahi-teitei, he whānuitia ngā tono i roto i ngā whatunga whakawhitiwhiti whatu piripono 100G/400G me ngā pokapū raraunga tere-tino-tiketike, ā, ka taea te whakatutuki i ngā tawhiti tuku roa neke atu i te 100 kiromita.
Ahakoa he maha ngā painga o te lithium niobate hei rauemi whakararuraru o te "huringa photon", ki te whakatauritea ki te silicon me te indium phosphide, he maha tonu ngā wā ka puta mai i te āhua o tētahi rauemi papatipu i roto i te taputapu, ka herea te mārama ki te arataki ngaru papatahi i hangaia e te horapa katote, te whakawhiti proton rānei, he iti noa te rerekētanga o te taupū whakaata (tata ki te 0.02), he nui te rahi o te taputapu. He uaua ki te whakatutuki i ngā hiahia o te whakaiti me te whakauru ongā taputapu whatu, ā, he rerekē tonu tana raina whakaputa mai i te raina tukatuka hiko-iti tuturu, ā, he raruraru utu nui, nō reira ko te hanganga kiriata angiangi he huarahi whanaketanga nui mō te lithium niobate e whakamahia ana i roto i ngā modulators hiko-whatu.
