He taiaho tere rawa te mahi, he rite te rahi ki te pito o te matihao

He mahi teiteirēseri tino terete rahi o te pito o te matimati

E ai ki tētahi tuhinga uhi hou i whakaputaina i roto i te hautaka Science, kua whakaatuhia e ngā kairangahau i te City University o New York tētahi huarahi hou hei waihanga i te mahi tino paingā taiaho tino terei runga i te nanophotonics. Ko tēnei aratau-raka itirēserika tukuna he raupapa o ngā pāorooro poto rawa o te mārama i ngā wā femtosecond (tiriona o te hēkona).

Aratau tere rawa te maukatingā taiahoka taea te āwhina i te wetewete i ngā mea ngaro o ngā wā tere rawa o te taiao, pērā i te hanganga, te pakaru rānei o ngā hononga ngota i te wā o ngā tauhohenga matū, te horapa rānei o te mārama i roto i ngā pāpāho pōrearea. Ko te tere teitei, te kaha o te pātītī tihi, me te whānuitanga o te whānuitanga o ngā taiaho raka-aratau ka taea hoki te whakamahi i ngā hangarau photon maha, tae atu ki ngā karaka ngota whatu, te whakaahua koiora, me ngā rorohiko e whakamahi ana i te mārama hei tatau me te tukatuka raraunga.

Engari ko ngā taiaho aratau-raka tino matatau he tino utu nui tonu, he pūnaha papamahi e hiahia ana ki te hiko, ā, he iti noa iho te whakamahinga i roto i te taiwhanga. Ko te whāinga o te rangahau hou ko te huri i tēnei hei pūnaha rahi maramara ka taea te whakaputa papatipu me te whakamahi i te mara. I whakamahia e ngā kairangahau he tūāpapa rauemi hou e puta ake ana i te lithium niobate kiriata-angiangi (TFLN) hei hanga tika me te whakahaere tika i ngā pāoro taiaho mā te whakamahi i ngā tohu hiko auau reo irirangi o waho ki reira. I whakakotahi te tīma i te whakanui taiaho teitei o ngā semiconductors akomanga III-V me ngā āheinga hanga pāoro whai hua o ngā arataki ngaru photonic nanoscale TFLN hei whakawhanake i tētahi taiaho e tuku ana i te mana tihi putanga teitei o te 0.5 watts.

Haunga tōna rahi kiato, he rite te rahi ki te pito o te matihao, he maha ngā āhuatanga o te taiaho raka-aratau kua whakaaturia hou nei kāore e taea e ngā taiaho tuku iho te whakatutuki, pērā i te kaha ki te whakarite tika i te tere whakahoki o te pāorooro putanga i runga i te whānuitanga o te 200 megahertz mā te whakarerekē noa i te iahiko papu. Ko te tumanako a te tīma kia tutuki he pūtake heru auau-tauine maramara mā te whirihoranga kaha o te taiaho, he mea nui mō te pūoko tika. Ko ngā tono mahi ko te whakamahi i ngā waea pūkoro hei tātaritanga i ngā mate kanohi, hei tātari rānei i te E. coli me ngā huaketo kino i roto i te kai me te taiao, me te whakahohe i te whakatere ina pakaru, kāore rānei e wātea ana te GPS.
