Ua hoʻomohala ka poʻe ʻimi noiʻi i kahi puʻupuʻu lahilahi loa me kahi kaapuni photonic i hoʻohui ʻia i hiki ke hoʻohana ʻia e hoʻohana i ka mea i kapa ʻia ʻo terahertz gap - e waiho ana ma waena o 0.3-30THz i ka spectrum electromagnetic - no ka spectroscopy a me ke kiʻi.
ʻO kēia āpau ke ʻano o kahi ʻenehana make ʻenehana, e wehewehe ana i nā alapine i wikiwiki loa no nā mea uila a me nā mea kelepona o kēia lā, akā lohi loa no ka optics a me nā noi kiʻi.
Eia nō naʻe, hiki i nā ʻepekema hou ke hiki iā lākou ke hana i nā nalu terahertz me ke alapine kūpono, ka lōʻihi hawewe, amplitude a me ka pae. Hiki i ia mana pololei ke hiki ke hoʻohana ʻia ka radiation terahertz no nā noi o ka hanauna e hiki mai ana ma nā ʻano uila a me ka optical.
ʻO ka hana, i alakaʻi ʻia ma waena o EPFL, ETH Zurich a me ke Kulanui o Harvard, ua paʻi ʻia maNature Communications.
Ua wehewehe ʻo Cristina Benea-Chelmus, ka mea nāna i alakaʻi i ka noiʻi ma ka Laboratory of Hybrid Photonics (HYLAB) ma ke kula ʻo ʻEnekinia o EPFL, ʻoiai ua hana ʻia nā hawewe terahertz ma kahi hoʻonohonoho lab ma mua, ua hilinaʻi mua nā ala mua i nā kristal nui e hana i nā alapine kūpono. Akā, ʻo ka hoʻohana ʻana o kāna lab i ke kaapuni photonic, i hana ʻia mai ka lithium niobate a i kālai maikaʻi ʻia ma ka nanometer scale e nā hoa hana ma ke Kulanui ʻo Harvard, e hana i kahi ala maʻalahi loa. ʻO ka hoʻohana ʻana i kahi substrate silicon e hana i ka mea kūpono no ka hoʻohui ʻana i nā ʻōnaehana uila a me ka optical.
"He mea paʻakikī loa ka hana ʻana i nā nalu ma nā alapine kiʻekiʻe loa, a he liʻiliʻi loa nā ʻenehana hiki ke hoʻohua iā lākou me nā hiʻohiʻona kūʻokoʻa," wehewehe ʻo ia. "Ua hiki iā mākou ke hana i kēia manawa ke ʻenekinia i ke ʻano maoli o nā nalu terahertz - e ʻōlelo maoli, 'makemake wau i kahi ʻano nalu e like me kēia.'”
No ka hoʻokō ʻana i kēia, ua hoʻolālā ʻo Benea-Chelmus' lab i ka hoʻonohonoho ʻana o ka chip i nā kahawai, i kapa ʻia ʻo waveguides, i mea e hiki ai ke hoʻohana ʻia nā antenna microscopic e hoʻolaha i nā hawewe terahertz i hana ʻia e ka mālamalama mai nā fiber optical.
"ʻO ka ʻoiaʻiʻo o ka hoʻohana ʻana o kā mākou hāmeʻa i kahi hōʻailona optical maʻamau he mea maikaʻi loa ia, no ka mea, ʻo ia ka mea hiki ke hoʻohana ʻia kēia mau chips hou me nā lasers kuʻuna, e hana maikaʻi loa a maopopo loa. Ua hoʻohui ʻo ia i nā mea liʻiliʻi e hoʻouna a loaʻa i nā hōʻailona ma ka pae terahertz hiki ke hana nui i nā ʻōnaehana kelepona ʻeono (6G).
I ka honua o ka optics, ʻike ʻo Benea-Chelmus i kahi kūpono no ka miniaturized lithium niobate chips i ka spectroscopy a me ke kiʻi. Ma waho aʻe o ka non-ionising, ʻoi aku ka haʻahaʻa o nā hawewe terahertz ma mua o nā ʻano nalu ʻē aʻe (e like me nā x-ray) i hoʻohana ʻia i kēia manawa no ka hāʻawi ʻana i ka ʻike e pili ana i ke ʻano o kahi mea - inā he iwi a he pena ʻaila paha. Hiki ke hāʻawi i kahi mea hoʻopaʻa paʻa ʻole e like me ka lithium niobate chip ke hāʻawi i kahi koho ʻoi aku ka liʻiliʻi i nā ʻenehana spectrographic o kēia manawa.
"Hiki iā ʻoe ke noʻonoʻo i ka hoʻouna ʻana i ka radiation terahertz ma o kahi mea āu e makemake ai a me ka nānā ʻana iā ia e ana i ka pane o ka mea, ma muli o kona ʻano mole.
Ma hope aʻe, hoʻolālā ʻo Benea-Chelmus e kālele ana i ka hoʻololi ʻana i nā waiwai o nā alakaʻi nalu a me nā antenna e ʻenekinia i nā ʻano nalu me nā amplitudes ʻoi aku ka nui, a ʻoi aku ka maikaʻi o nā alapine a me nā helu palaho. ʻIke pū ʻo ia i ka pono o ka ʻenehana terahertz i hoʻomohala ʻia i kāna lab e pono ai no nā noi quantum.
"He nui nā nīnau koʻikoʻi e hoʻoponopono ai; no ka laʻana, makemake mākou inā hiki iā mākou ke hoʻohana i ia mau chips e hana i nā ʻano hou o ka radiation quantum hiki ke hoʻohana ʻia i nā manawa pōkole loa.
