Roanga mahapūtake māramai runga i te pepa papatahi
Ko ngā maramara whatu te ara e kore e taea te karo hei pupuri i te Ture a Moore, kua riro hei whakaae whānuitia e te ao mātauranga me te ahumahi, ka taea e ia te whakaoti rapanga tere me te whakapau kaha e pā ana ki ngā maramara hiko, e tika ana kia hurihia te heke mai o te rorohiko atamai me te tere-tino-tiketike.whakawhitiwhiti kōrero whatuI ngā tau tata nei, he whanaketanga hangarau nui i roto i te hangarau whakaahua e ahu mai ana i te silicon e aro ana ki te whanaketanga o ngā heru auau whatu soliton taumata-iti maramara, ka taea te whakaputa i ngā heru auau mokowā ōrite mā roto i ngā heru whatu. Nā ōna painga o te whakaurunga teitei, te whānuitanga o te whānuitanga me te auau auau teitei, he maha ngā tono pea o te pūtake mārama soliton taumata-iti maramara i roto i te whakawhitiwhiti kaha nui, te tirotiro matawai,ngā taputapu whakaahua ngaruiti, te ine tika me ētahi atu mara. I te nuinga o te wā, ko te whai huatanga o te huringa o te heru auau whatu soliton kotahi o te moroiti ka whakawhāitihia e ngā tawhā e tika ana o te moroiti whatu. I raro i tētahi mana papu motuhake, he maha ngā wā ka whakawhāitihia te mana putanga o te heru auau whatu soliton kotahi o te moroiti. Ko te whakaurunga o te pūnaha whakanui whatu o waho ka pā ki te ōwehenga tohu-ki-haruru. Nō reira, ko te kōtaha whāiti papatahi o te heru auau whatu soliton moroiti kua riro hei kaupapa matua o tēnei mara.
Nō nā tata nei, kua tino ahu whakamua tētahi rōpū rangahau i Singapore i roto i te mara o ngā pūtake mārama maha-ngaru i runga i ngā pepa papatahi. I whakawhanakehia e te rōpū rangahau tētahi maramara moroiti whatu me te whānuitanga papatahi, whānui, me te tata kore marara, ā, i tākai pai i te maramara whatu me te hononga taha (te ngaronga hononga iti iho i te 1 dB). I runga i te maramara moroiti whatu, ka hinga te pānga wera-whatu kaha i roto i te moroiti whatu mā te kaupapa hangarau o te papu takirua, ā, ka tutuki te pūtake mārama maha-ngaru me te putanga whānuitanga papatahi. Mā te pūnaha whakahaere urupare, ka taea e te pūnaha pūtake soliton maha-ngaru te mahi pumau mō te neke atu i te 8 hāora.
Ko te putanga hihi o te pūtake mārama he āhua trapezoidal, ko te tere whakahokinga he tata ki te 190 GHz, ko te hihi papatahi e kapi ana i te 1470-1670 nm, ko te papatahi he tata ki te 2.2 dBm (paerewa rerekētanga), ā, ko te whānuitanga hihi papatahi e kapi ana i te 70% o te whānuitanga hihi katoa, e kapi ana i te roopu S+C+L+U. Ka taea te whakamahi i ngā hua rangahau i roto i te hononga whatu kaha-teitei me te whānuitanga-teitei.whatungā pūnaha rorohiko. Hei tauira, i roto i te pūnaha whakaaturanga whakawhitiwhiti kōrero kaha-nui e hangai ana ki te pūtake heru soliton moroiti, ko te rōpū heru auau me te rerekētanga pūngao nui e pā ana ki te raruraru o te SNR iti, ko te pūtake soliton me te putanga hihi papatahi ka taea te wikitoria i tēnei raruraru me te āwhina ki te whakapai ake i te SNR i roto i te tukatuka mōhiohio whatu whakarara, he mea nui tēnei ki te hangarau.
Ko te tuhinga nei, ko "Flat soliton microcomb source" te taitara, i whakaputaina hei pepa uhi i roto i te Opto-Electronic Science hei wāhanga o te putanga "Digital and Intelligent Optics".
