Ka whakaurua mai ngā taputapu whakaahua tere-teitei eNgā pūoko whakaahua InGaAs
Ngā pūoko whakaahua tere-teiteii roto i te mara o te whakawhitiwhiti kōrero whatu ko ngā taputapu whakaahua III-V InGaAs me te IV Si me Ge/ katoaNgā taputapu whakaahua SiKo te mea tuatahi he taputapu tirotiro tata-whero tuku iho, kua roa nei e noho matua ana, ko te mea tuarua e whakawhirinaki ana ki te hangarau whatu silicon hei whetu e ara ake ana, ā, he wāhi wera i roto i te mara o te rangahau hikohiko o te ao i ngā tau tata nei. Hei tāpiri, kei te tere te whanaketanga o ngā taputapu tirotiro hou e ahu mai ana i te perovskite, ngā rauemi waro me ngā rauemi rua-ahu nā te mea he ngāwari te tukatuka, he pai te ngāwari me ngā āhuatanga ka taea te whakarerekē. He rerekētanga nui i waenga i ēnei taputapu tirotiro hou me ngā taputapu tirotiro whakaahua kore-waro tuku iho i roto i ngā āhuatanga rauemi me ngā tukanga hanga. He tino pai ngā āhuatanga mimiti mārama me te kaha kawe utu pai o ngā taputapu tirotiro perovskite, he whānui te whakamahinga o ngā taputapu tirotiro rauemi waro nā te iti o te utu me te ngāwari o ngā irahiko, ā, kua nui te aro ki ngā taputapu tirotiro rauemi rua-ahu nā ō rātou āhuatanga ā-tinana ahurei me te nekenekehanga kawe teitei. Heoi, ki te whakatauritea ki ngā taputapu tirotiro InGaAs me Si/Ge, me whakapai tonu ngā taputapu tirotiro hou i runga i te pumau mo te wā roa, te pakeketanga hanga me te whakaurunga.
Ko te InGaAs tētahi o ngā rauemi tino pai mō te whakatutuki i ngā taputapu whakaahua tere-teitei me te urupare-teitei. Tuatahi, he rauemi haurua whakawhiti tika te InGaAs, ā, ka taea te whakahaere i tōna whānui o te whakawhiti mā te ōwehenga i waenga i te In me te Ga kia taea ai te kimi i ngā tohu whatu o ngā roangaru rerekē. I roto i ēnei, he tino ōrite te In0.53Ga0.47As ki te whatunga papa o te InP, ā, he nui te tauwehenga mimiti mārama i roto i te roopu whakawhitiwhiti whatu, koinei te mea e whakamahia whānuitia ana i roto i te whakarite onga kaitirotiro whakaahua, ā, ko te mahi o te au pōuri me te urupare hoki te mea pai rawa atu. Tuarua, he tere tere te nekeneke o ngā irahiko o ngā rauemi InGaAs me InP, ā, ko te tere nekeneke o ngā irahiko kua kōtuitia he tata ki te 1×107 cm/s. I taua wā anō, he pānga tere tere irahiko ngā rauemi InGaAs me InP i raro i te mara hiko motuhake. Ka taea te wehewehe i te tere nekeneke ki te 4×107cm/s me te 6×107cm/s, he mea e pai ana mō te whakatutuki i tētahi whānui whānui nui ake o te kaikawe. I tēnei wā, ko te pūoko whakaahua InGaAs te pūoko whakaahua tino rongonui mō te whakawhitiwhiti kōrero whatu, ā, ko te tikanga hononga taunga mata te nuinga o te wā e whakamahia ana i te mākete, ā, kua kitea ngā hua pūoko taunga mata 25 Gbaud/s me te 56 Gbaud/s. Kua whakawhanakehia hoki ngā pūoko taunga mata iti ake, taunga whakamuri me te whānui whānui nui, e pai ana mō ngā tono tere teitei me te taunga tiketike. Heoi, he iti te aratau hononga o te pūoko taunga mata, ā, he uaua ki te whakauru atu ki ētahi atu taputapu hiko opto. Nō reira, me te whakapai ake i ngā whakaritenga whakauru hikohiko, kua noho haere ngā taputapu whakaahua InGaAs hono ngaru-arataki he pai te mahi, ā, he pai mō te whakauru, hei kaupapa matua mō te rangahau, i roto i ēnei ko ngā waeine whakaahua InGaAs arumoni 70 GHz me te 110 GHz e whakamahi ana i ngā hanganga hono ngaru-arataki. E ai ki ngā rauemi papa rerekē, ka taea te wehewehe i te taputapu whakaahua InGaAs hono ngaru-arataki kia rua ngā wāhanga: InP me Si. He kounga teitei te rauemi epitaxial i runga i te papa InP, ā, he pai ake mō te whakarite i ngā taputapu mahi-teitei. Heoi, ko ngā rerekētanga i waenga i ngā rauemi III-V, ngā rauemi InGaAs me ngā papa Si i whakatipuhia, i herea rānei ki runga i ngā papa Si ka arahi ki te kounga rauemi, ki te atanga rānei he iti, ā, he nui tonu te wāhi hei whakapai ake i te mahi a te taputapu.
