An kaiwhakarerekē hiko-whatui runga i ngā hanganga rerekē, ngā roangaru, me ngā tūāpapa o te niobate lithium kiriata angiangi, me te whakatairite mahi whānui o ngā momo rerekēNgā kaiwhakarerekētanga EOM, me te tātaritanga o te rangahau me te whakamahinga ongā kaiwhakarerekētanga kiriata angiangi lithium niobatei roto i ētahi atu mara.
1. Kaiwhakarerekētanga kiriata angiangi lithium niobate kore-haurua
Ko tēnei momo whakarerekētanga e hangai ana ki te pānga hiko-whatu pai rawa atu o te tioata lithium niobate, ā, he taputapu matua mō te whakatutuki i te whakawhitiwhitinga whatu tere-teitei me te tawhiti-roa. E toru ngā hanganga matua:
1.1 Te whakarerekētanga MZI hiko ngaru haere: Koinei te hoahoa tino noa. I te tau 2018, i tutuki tuatahitia e te rōpū rangahau Lon č ar i Te Whare Wānanga o Harvard tētahi putanga mahi-teitei, me ngā whakapainga i muri mai tae atu ki te uta capacitive i runga i ngā papa quartz (he whānui te whānuitanga engari kāore e hototahi ki te hanga-silicon) me te hototahi-silicon i runga i te whakakohao papa, i tutuki ai te whānui teitei (>67 GHz) me te tuku tohu tere-teitei (pēnei i te 112 Gbit/s PAM4).
1.2 Te whakarerekētanga MZI takai: Hei whakapoto i te rahi o te taputapu me te urutau ki ngā kōwae kiato pēnei i te QSFP-DD, ka whakamahia ngā irahiko maimoatanga pōraritanga, te arataki whakawhiti, te hanganga moroiti rānei hei whakaiti i te roa o te taputapu mā te haurua, kia tutuki ai te whānui o te 60 GHz.
1.3 Te Pūwhakarerekētanga Kotahi/Rua o te Polarization Coherent Orthogonal (IQ): Ka whakamahi i te whakatakotoranga whakarerekētanga teitei hei whakarei ake i te tere tuku. I tutuki i te rōpū rangahau Cai i Te Whare Wānanga o Sun Yat sen te tuatahi o ngā pūwhakarerekētanga IQ kotahi-maramara i runga i te maramara i te tau 2020. He pai ake te mahi a te pūwhakarerekētanga IQ rua-polarization i whakawhanakehia i te heke mai, ā, ko te putanga i runga i te papa quartz kua whakatakoto i te rekoata tere tuku roangaru kotahi o te 1.96 Tbit/s.
2. Momo kōhao angiangi o te rīhiuma niobate kiriata-angiangi
Hei whakatutuki i ngā whakarerekētanga whānui tino iti me te nui, he maha ngā hanganga kōhao resonant e wātea ana:
2.1 Te karaihe whakaahua (PC) me te kaiwhakatikatika mowhiti moroiti: Kua whakawhanakehia e te rōpū rangahau a Lin i Te Whare Wānanga o Rochester te kaiwhakatikatika karaihe whakaahua mahi-teitei tuatahi. Hei tāpiri, kua whakaarohia hoki ngā kaiwhakatikatika mowhiti moroiti e hangai ana ki te whakaurunga heterogeneous silicon lithium niobate me te whakaurunga homogeneous, e tutuki ai ngā whānui o te maha GHz.
2.2 Kaiwhakatikatika kōhao resonant grating Bragg: tae atu ki te kōhao Fabry Perot (FP), te grating Bragg arai-ngaru (WBG), me te kaiwhakatikatika mārama puhoi (SL). Kua hangaia ēnei hanganga hei whakataurite i te rahi, ngā ātete tukanga, me te mahi, hei tauira, ka tutuki i te kaiwhakatikatika kōhao resonant 2 × 2 FP te whānui o te whānui e neke atu ana i te 110 GHz. Ka whakawhānuihia e te kaiwhakatikatika mārama puhoi i runga i te kupenga Bragg hono te whānuitanga o te whānui mahi.
3. Pūwhakarerekētanga kiriata angiangi lithium niobate whakauru rerekē
E toru ngā tikanga whakauru matua hei whakakotahi i te hototahitanga o te hangarau CMOS i runga i ngā tūāpapa e hangai ana ki te silicon me te mahi whakarerekētanga pai rawa atu o te lithium niobate:
3.1 Te whakaurunga momo here rerekē: Mā te hononga tika ki te benzocyclobutene (BCB) me te silicon dioxide, ka whakawhitia te lithium niobate kiriata angiangi ki tētahi tūāpapa silicon, silicon nitride rānei, ka tutuki ai te taumata wafer, te whakaurunga pumau pāmahana teitei. Ka whakaatuhia e te modulator te whānui whānui teitei (>70 GHz, tae atu ki te neke atu i te 110 GHz) me te kaha tuku tohu tere-teitei.
3.2 Te whakaurunga kanorau o ngā rauemi arataki ngaru whakatakoto: mā te whakatakoto i te silicon, i te silicon nitride rānei ki runga i te kiriata angiangi lithium niobate hei arataki ngaru kawenga ka tutuki hoki te whakatikatika hiko-whatu whai hua.
3.3 Te whakaurunga rerekē o te tānga whakawhiti moroiti (μ TP): He hangarau tēnei e whakaarohia ana kia whakamahia mō te whakaputanga tauine nui, e whakawhiti ana i ngā taputapu mahi kua oti te hanga ki ngā maramara ūnga mā roto i ngā taputapu tino tika, me te karo i te tukatuka-muri uaua. Kua angitu te whakamahi ki te silicon nitride me ngā tūāpapa e hangai ana ki te silicon, ā, kua tutuki te whānuitanga o ngā tekau GHz.
Hei whakarāpopototanga, ka whakamāramahia e tēnei tuhinga te mahere hangarau o ngā whakarerekētanga hiko-whatu i runga i ngā tūāpapa lithium niobate kiriata angiangi, mai i te whai i ngā hanganga kōhao kore-whakaoho teitei me te whānui-rahi, te tūhura i ngā hanganga kōhao whakaoho iti, me te whakauru atu ki ngā tūāpapa photonic kua pakari e hangai ana ki te silicon. E whakaatu ana i te kaha nui me te ahunga whakamua tonu o ngā whakarerekētanga lithium niobate kiriata angiangi ki te pakaru i te aukati mahi o ngā whakarerekētanga tuku iho me te whakatutuki i te whakawhitiwhitinga whatu tere-teitei.
