Nō nā tata nei i akohia mai i Te Whare Wānanga o te Pūtaiao me te Hangarau o Haina, i whakaarohia e te tīma tohunga mātauranga o te whare wānanga o Guo Guangcan, a Ahorangi Dong Chunhua, me tana hoa mahi a Zou Changling, he tikanga whakahaere marara moroiti whānui, hei whakatutuki i te whakahaere motuhake i te auau whatu me te auau auau auau, ā, i whakamahia ki te ine tika o te roanga ngaru whatu, ka piki ake te tika o te ine roanga ngaru ki te kilohertz (kHz). I whakaputaina ngā kitenga ki Nature Communications.
Kua kukume mai te aro nui ki ngā rangahau mō ngā moroiti Soliton i ahu mai i ngā moroiti whatu i roto i ngā mara o te tirotiro matatika me ngā karaka whatu. Heoi, nā te awe o te haruru taiao me te haruru taiaho me ngā pānga kore-raina atu i roto i te moroiti, he iti rawa te pumau o te moroiti soliton, ka waiho hei arai nui i roto i te whakamahinga mahi o te heru taumata mārama iti. I roto i ngā mahi o mua, i whakaūhia e ngā kaipūtaiao te heru auau whatu mā te whakahaere i te taupū whakaata o te rauemi, i te āhuahanga rānei o te moroiti kia tutuki ai te urupare wā-tūturu, i puta ai ngā huringa tata-ōrite i roto i ngā momo oro katoa i roto i te moroiti i te wā kotahi, kāore i te kaha ki te whakahaere motuhake i te auau me te whakahokinga o te heru. Ka tino whakawhāitihia e tēnei te whakamahinga o te heru mārama iti i roto i ngā whakaaturanga mahi o te tirotiro matatika, ngā irahiko ngaruiti, te whānuitanga whatu, me ētahi atu.
Hei whakaoti i tēnei raruraru, i whakaarohia e te tīma rangahau tētahi tikanga ā-tinana hou hei whakatinana i te whakahaere wā-tūturu motuhake o te auau pokapū me te auau tāruarua o te heru auau whatu. Mā te whakauru i ngā tikanga whakahaere marara moroiti-kōhao e rua, ka taea e te tīma te whakahaere motuhake i te marara o ngā momo momo kōhao moroiti, kia taea ai te whakahaere katoa i ngā auau niho rerekē o te heru auau whatu. He whānui tēnei tikanga whakahaere marara ki ngā tūāpapa photonic whakauru rerekē pērā i te silicon nitride me te lithium niobate, kua whānuitia te rangahau.
I whakamahia e te tīma rangahau te rēhia papu me te rēhia āwhina hei whakahaere motuhake i ngā momo ā-wāhi o ngā momo rerekē o te kōhao iti hei whakatutuki i te pumau urutau o te auau aratau papu me te whakahaere motuhake o te auau auau auau. I runga i te rēhia whatu, i whakaatu te tīma rangahau i te whakahaere tere, ka taea te whakarite o ngā auau auau noa, ā, i whakamahia ki te ine tika o te roa o te ngaru, e whakaatu ana i te mita ngaru me te tika o te ine o te raupapa o te kilohertz me te kaha ki te ine i ngā roangaru maha i te wā kotahi. Ki te whakatauritea ki ngā hua rangahau o mua, kua eke te tika o te ine i tutukihia e te tīma rangahau ki te toru ngā taumata whakapainga.
Ko ngā moroiti soliton ka taea te whirihora anō i whakaaturia i roto i tēnei hua rangahau te pūtake mō te whakatutukitanga o ngā paerewa auau whatu iti te utu, kua whakauruhia ki roto i ngā maramara, ka whakamahia ki roto i te ine tika, te karaka whatu, te tirotiro matawai me te whakawhitiwhiti kōrero.
