Te whakapolarization hiko-whatuka whakatutukihia te mana whakahaere mā te tuhituhi taiaho femtosecond me te whakarerekētanga karaihe wai
Kua whakawhanakehia e ngā kairangahau i Tiamana tētahi tikanga hou mō te whakahaere tohu whatu mā te whakakotahi i te tuhituhi taiaho femtosecond me te tioata wai.whakarerekētanga hiko-whatuMā te whakauru i te paparanga tioata wai ki roto i te arataki ngaru, ka tutuki te mana whakahaere hiko-whatu o te āhua porowhita hihi. Ka whakatuwherahia e te hangarau ngā huarahi hou mō ngā taputapu e hangai ana ki te maramara me ngā ara iahiko photonic matatini i hangaia mā te whakamahi i te hangarau tuhi laser femtosecond. I whakaahuahia e te rōpū rangahau te āhua i hangaia ai e rātou ngā pereti ngaru ka taea te whakarerekē i roto i ngā arataki ngaru silicon kua whakakotahihia. Ina tukuna he ngaohiko ki te tioata wai, ka huri ngā ngota tioata wai, ka huri i te āhua porowhita o te mārama e tukuna ana i roto i te arataki ngaru. I roto i ngā whakamātautau i mahia, i angitu ngā kairangahau ki te whakarerekē katoa i te porowhita o te mārama i ngā roangaru e rua e kitea ana (Pikitia 1).
Te whakakotahi i ngā hangarau matua e rua hei whakatutuki i te ahunga whakamua auaha i roto i ngā taputapu whakauru photonic 3D
Ko te kaha o ngā taiaho femtosecond ki te tuhi tika i ngā arataki ngaru ki roto rawa i te rauemi, kaua ki runga noa i te mata, he hangarau whai hua hei whakanui ake i te maha o ngā arataki ngaru i runga i te maramara kotahi. Ka mahi te hangarau mā te arotahi i tētahi hihi taiaho kaha-teitei ki roto i tētahi rauemi mārama. Ina tae te kaha o te mārama ki tētahi taumata, ka huri te hihi i ngā āhuatanga o te rauemi i tōna wāhi tono, pērā i te pene he tika te micron.
I whakakotahi te tīma rangahau i ngā tikanga photon taketake e rua hei whakauru i tētahi paparanga tioata wai ki roto i te arataki ngaru. I te haere o te hihi mā roto i te arataki ngaru me te tioata wai, ka huri te āhua me te pōraritanga o te hihi ina whakamahia he mara hiko. Muri iho, ka haere tonu te hihi whakarerekētia ki te horapa mā roto i te wāhanga tuarua o te arataki ngaru, ā, ka tutuki te tuku o te tohu whatu me ngā āhuatanga whakarerekētanga. Mā tēnei hangarau ranu e whakakotahi ana i ngā hangarau e rua ka taea ngā painga o ngā mea e rua i roto i te taputapu kotahi: i tētahi taha, ko te nui o te kukū mārama i puta mai i te pānga arataki ngaru, ā, i tētahi atu taha, ko te nui o te whakarerekētanga o te tioata wai. Ka whakatuwherahia e tēnei rangahau he huarahi hou hei whakamahi i ngā āhuatanga o ngā tioata wai hei whakauru i ngā arataki ngaru ki roto i te rahinga katoa o ngā taputapu.ngā kaiwhakarerekēmōngā taputapu whakaahua.
Pikitia 1 I whakauruhia e ngā kairangahau ngā paparanga karaihe wai ki roto i ngā arataki ngaru i hangaia e te tuhi taiaho tika, ā, ka taea te whakamahi i te taputapu ranu hua hei whakarerekē i te porowhita o te mārama e haere ana i roto i ngā arataki ngaru.
Te whakamahinga me ngā painga o te karaihe wai i roto i te whakarerekētanga arataki ngaru taiaho femtosecond
Ahakoawhakarerekētanga whatuI roto i ngā arataki ngaru tuhi taiaho femtosecond i tutukihia i mua mā te whakamahi i te whakamahana ā-rohe ki ngā arataki ngaru, i roto i tēnei rangahau, i whakahaerea tika te whakapōraru mā te whakamahi i ngā tioata wai. "He maha ngā painga pea o tā mātou huarahi: he iti ake te whakamahinga hiko, te kaha ki te tukatuka takitahi i ngā arataki ngaru, me te whakaiti i te pokanoa i waenga i ngā arataki ngaru tata," te kī a ngā kairangahau. Hei whakamātautau i te whai huatanga o te taputapu, i werohia e te tīma he taiaho ki roto i te arataki ngaru, ā, i whakarerekē i te mārama mā te whakarerekē i te ngaohiko i tukuna ki te paparanga tioata wai. Ko ngā huringa whakapōraru i kitea i te putanga he rite ki ngā tumanakohanga ariā. I kitea anō e ngā kairangahau i muri i te whakaurunga o te tioata wai ki te arataki ngaru, kāore i rerekē ngā āhuatanga whakarerekētanga o te tioata wai. E whakanui ana ngā kairangahau he tohu noa iho te rangahau, nō reira he nui tonu ngā mahi hei mahi i mua i te whakamahinga o te hangarau i roto i te mahi. Hei tauira, ka whakarerekēhia e ngā taputapu o nāianei ngā arataki ngaru katoa i te ara kotahi, nō reira kei te mahi te tīma ki te whakatutuki i te mana motuhake o ia arataki ngaru takitahi.
