Te roangaru-mahapuna maramai runga i te papa papatahi
Ko nga maramara whatu te huarahi e kore e taea te haere tonu i te Ture a Moore, kua noho hei whakaaro mo te whare wananga me te ahumahi, ka taea e ia te whakaoti i nga raru tere me te whakapau hiko e pa ana ki nga maramara hiko, e tika ana kia huri te heke mai o te rorohiko mohio me te tere-tere.whakawhitiwhiti whatu. I roto i nga tau tata nei, he mea nui te pakaruhanga hangarau i roto i nga whakaahua-a-kirika e aro ana ki te whakawhanaketanga o nga heru whatu whatu o te microcavity soliton taumata maramara, e taea ai te whakaputa heru mokowhiti riterite i roto i nga microcavities whatu. Na ona painga o te whakaurunga teitei, te whanui whanui me te nui o te tukuruatanga, ko te maramara maramara microcavity soliton te puna marama he maha nga tono mo te whakawhitiwhiti kaha nui, spectroscopy,ngaruiti whakaahua, inenga tika me etahi atu mara. I te nuinga o te waa, ko te kaha o te hurihanga o te microcavity kotahi soliton heru whatu whatu he maha nga wa e iti ana e nga tawhā e tika ana o te microcavity whatu. I raro i te mana papu motuhake, he iti noa te mana whakaputa o te microcavity single soliton optical heru. Ko te whakaurunga o te punaha whakakaha whatu o waho ka pa ki te owehenga tohu-ki-haruru. Na reira, ko te ahua papatahi o te microcavity soliton heru whatu whatu hei whai mo tenei mara.
I tata nei, he nui te ahunga whakamua a tetahi roopu rangahau i Singapore i roto i te waahanga o nga puna marama-maha-roa i runga i nga pepa papatahi. I whakawhanakehia e te roopu rangahau he maramara microcavity whatu me te papatahi, te whanui whanui me te tata ki te kore marara, me te pai ki te kii i te maramara whatu me te hono taha (he iti iho i te 1 dB te ngaronga hono). I runga i te maramara microcavity whatu, te kaha thermo-optical pānga i roto i te microcavity whatu e hinga e te kaupapa hangarau o rua papua, me te puna marama maha-roa me te putanga spectral flat te ite. Na roto i te punaha whakahaere urupare, ka taea e te punaha puna soliton te roangaru-maha te mahi mo te neke atu i te 8 haora.
Ko te putanga matakite o te puna marama he ahua trapezoidal, ko te reeti tukurua he 190 GHz, he 1470-1670 nm te papatahi, he 2.2 dBm te paanui (paerewa ine), a ko te awhe hihinga papatahi kei te 70% o te katoa. awhe momotu, e hipoki ana i te roopu S+C+L+U. Ka taea te whakamahi i nga hua rangahau i roto i te hononga whatu kaha-nui me te rahi-nuiwhatupūnaha rorohiko. Hei tauira, i roto i te punaha whakaatu korero kaha-nui i runga i te puna heru microcavity soliton, ko te roopu heru auau he nui te rereketanga o te kaha e pa ana ki te raru o te SNR iti, ko te puna soliton me te putanga matakite papatahi ka taea te wikitoria i tenei raru me te awhina ki te whakapai ake i te. SNR i roto i te whakarara tukatuka korero whatu, e whai hiranga engineering nui.
Ko te mahi, ko "Flat soliton microcomb source," i whakaputaina hei pepa uhi i Opto-Electronic Science hei wahanga o te take "Digital and Intelligent Optics".
