Ua aʻo hou ʻia mai ke Kulanui o ʻEpekema a me ʻenehana o Kina, ʻo ke kulanui o Guo Guangcan ka hui kumu kula ʻo Professor Dong Chunhua a me ka hoa hana ʻo Zou Changling i manaʻo i kahi micro-cavity dispersion control mechanism, e hoʻokō i ka mana kūʻokoʻa kūʻokoʻa o ka optical frequency comb center. alapine (frequency and repetition frequency, and repetition frequency, and applicable to the precision ana precision of optical wavelength, the wavelength ana accuracy correctly to kilohertz (kHz).Ua paʻi ʻia nā ʻike ma Nature Communications.
ʻO nā microcombs Soliton i hoʻokumu ʻia i nā microcavities optical ua hoihoi nui i ka noiʻi noiʻi ma nā kahua o ka spectroscopy pololei a me nā uaki optical.Eia nō naʻe, ma muli o ka hopena o ka leo kaiapuni a me ka leo laser a me nā hopena nonlinear hou i loko o ka microcavity, ua kaupalena ʻia ke kūpaʻa o ka microcomb soliton, a lilo ia i mea keakea nui i ka hoʻohana pono ʻana o ka pale haʻahaʻa māmā.Ma ka hana ma mua, ua hoʻokūpaʻa a hoʻomalu nā ʻepekema i ka hui ʻana o ka optical frequency ma o ka hoʻomalu ʻana i ka index refractive o ka mea a i ʻole ka geometry o ka microcavity e hoʻokō i ka manaʻo manawa maoli, kahi i hoʻololi kokoke i nā ʻano like ʻole i nā ʻano resonance āpau i ka microcavity i ka like. ka manawa, nele i ka hiki ke hoʻomalu kūʻokoʻa i ka pinepine a me ka hana hou ʻana o ka pulu.Hoʻopili loa kēia i ka hoʻohana ʻana i ka huila haʻahaʻa haʻahaʻa i nā hiʻohiʻona kūpono o ka spectroscopy precision, microwave photons, optical ranging, etc.
No ka hoʻoponopono ʻana i kēia pilikia, ua noi ka hui noiʻi i kahi hana kino hou e ʻike ai i ka hoʻoponopono kūʻokoʻa kūʻokoʻa o ke alapine waena a me ke alapine repetition o ka mea hoʻopili alapine optical.Ma ka hoʻokomo ʻana i ʻelua mau ʻano mana hoʻopuehu micro-cavity, hiki i ka hui ke hoʻomalu kūʻokoʻa i ka hoʻopuehu ʻana o nā kauoha like ʻole o ka micro-cavity, i hiki ai ke hoʻokō i ka mana piha o nā alapine niho like ʻole o ka pulupulu pinepine optical.ʻO kēia kaʻina hoʻoponopono hoʻopuehu i ka honua āpau i nā pae photonic like ʻole e like me ka silicon nitride a me ka lithium niobate, i aʻo nui ʻia.
Ua hoʻohana ka hui noiʻi i ka laser pumping a me ka laser auxiliary e hoʻomalu kūʻokoʻa i nā ʻano spatial o nā kauoha like ʻole o ka microcavity e ʻike ai i ke kūpaʻa adaptive o ke alapine pumping mode a me ka hoʻoponopono kūʻokoʻa o ka frequency comb repetition frequency.Ma muli o ka lelu opua, ua hōʻike ka pūʻulu noiʻi i ka hoʻoponopono wikiwiki a hiki ke hoʻonohonoho ʻia o nā alapine hoʻoluʻu a hoʻohana ʻia i ke ana pololei o ka lōʻihi o ka nalu, e hōʻike ana i kahi mika nalu me ke ana pololei o ke kauoha o kilohertz a me ka hiki ke ana i nā nalu he nui i ka manawa like.Ke hoʻohālikelike ʻia me nā hualoaʻa noiʻi mua, ʻo ke ana ʻana i hoʻokō ʻia e ka hui noiʻi ua hiki i ʻekolu mau kauoha o ka hoʻomaikaʻi nui.
ʻO nā microcombs soliton reconfigurable i hōʻike ʻia i loko o kēia hopena noiʻi e waiho i ke kumu no ka hoʻokō ʻana i nā kumu kūʻai haʻahaʻa, chip integrated optical frequency standard, e hoʻohana ʻia i ke ana pololei, uaki optical, spectroscopy a me ke kamaʻilio.
