ʻO ke aʻo nui ʻana o Micro-nano photonics i ke kānāwai o ka launa pū ʻana ma waena o ka mālamalama a me nā mea ma ka pae micro a me nano a me kāna noi ʻana i ka hanauna mālamalama, ka hoʻoili ʻana, ka hoʻoponopono ʻana, ka ʻike ʻana a me ka ʻike ʻana. Hiki i nā mea hana sub-wavelength micro-nano photonics ke hoʻomaikaʻi maikaʻi i ke kiʻekiʻe o ka hoʻohui photon, a manaʻo ʻia e hoʻohui i nā mea photonic i loko o kahi chip optical liʻiliʻi e like me nā chips uila. ʻO ka Nano-surface plasmonics kahi kahua hou o micro-nano photonics, kahi e aʻo nui ai i ka launa pū ʻana ma waena o ka mālamalama a me nā mea i loko o nā nanostructures metala. Loaʻa iā ia nā ʻano o ka liʻiliʻi, ka wikiwiki kiʻekiʻe a me ka lanakila ʻana i ka palena diffraction kuʻuna. ʻO ka hoʻolālā Nanoplasma-waveguide, nona ka hoʻonui ʻana i ke kahua kūloko maikaʻi a me nā ʻano kānana resonance, ke kumu o ka nano-filter, wavelength division multiplexer, optical switch, laser a me nā mea hana micro-nano optical ʻē aʻe. Hoʻopaʻa nā microcavities optical i ka mālamalama i nā wahi liʻiliʻi a hoʻonui nui i ka launa pū ʻana ma waena o ka mālamalama a me nā mea. No laila, ʻo ka microcavity optical me ke kumu kiʻekiʻe he ala koʻikoʻi ia o ka ʻike kiʻekiʻe a me ka ʻike ʻana.
Ka lua liʻiliʻi o WGM
I nā makahiki i hala iho nei, ua huki nui ka microcavity optical i ka nānā ʻana ma muli o kona hiki ke hoʻohana nui ʻia a me ke koʻikoʻi ʻepekema. ʻO ka microcavity optical ka mea nui o ka microsphere, microcolumn, microring a me nā geometries ʻē aʻe. He ʻano resonator optical hilinaʻi morphologic ia. Hōʻike piha ʻia nā nalu māmā i loko o nā microcavities ma ka interface microcavity, e hopena ana i kahi ʻano resonance i kapa ʻia ʻo whispering gallery mode (WGM). Ke hoʻohālikelike ʻia me nā resonators optical ʻē aʻe, loaʻa i nā microresonators nā ʻano o ka waiwai Q kiʻekiʻe (ʻoi aku ma mua o 106), ka nui mode haʻahaʻa, ka liʻiliʻi a me ka hoʻohui maʻalahi, a pēlā aku, a ua hoʻopili ʻia i ka ʻike biochemical kiʻekiʻe-sensitivity, ultra-low threshold laser a me ka hana nonlinear. ʻO kā mākou pahuhopu noiʻi ka ʻimi a me ke aʻo ʻana i nā ʻano o nā ʻano like ʻole a me nā morphologies like ʻole o nā microcavities, a e hoʻopili i kēia mau ʻano hou. ʻO nā kuhikuhi noiʻi nui e pili ana i: ka noiʻi ʻana i nā ʻano optical o ka microcavity WGM, ka noiʻi hana o ka microcavity, ka noiʻi noi o ka microcavity, a pēlā aku.
ʻIke biochemical microcavity WGM
I ka hoʻokolohua, ua hoʻohana ʻia ke ʻano WGM kiʻekiʻe ʻehā-kauoha M1 (FIG. 1(a)) no ke ana ʻana i ka ʻike ʻana. I ka hoʻohālikelike ʻana me ke ʻano haʻahaʻa, ua hoʻomaikaʻi nui ʻia ka ʻike o ke ʻano kiʻekiʻe (FIG. 1(b)).
Kiʻi 1. ʻAno resonance (a) o ka lua microcapillary a me kona ʻike index refractive e pili ana (b)
Kānana optical hiki ke hoʻololi ʻia me ka waiwai Q kiʻekiʻe
ʻO ka mea mua, ua huki ʻia ka radial cylindrical microcavity e loli mālie ana, a laila hiki ke hoʻokō ʻia ka hoʻonohonoho ʻana o ka wavelength ma ka hoʻoneʻe ʻana i ke kūlana coupling ma muli o ke kumumanaʻo o ka nui o ke ʻano mai ka wavelength resonant (Kiʻi 2 (a)). Hōʻike ʻia ka hana tunable a me ka bandwidth kānana ma ke Kiʻi 2 (b) a me (c). Eia kekahi, hiki i ka hāmeʻa ke hoʻokō i ka ʻike ʻana i ka neʻe ʻana o ka optical me ka pololei sub-nanometer.
Kiʻi 2. Kiʻikuhi kiʻikuhi o ke kānana optical hiki ke hoʻololi ʻia (a), ka hana hiki ke hoʻololi ʻia (b) a me ka bandwidth kānana (c)
Mea hoʻoheheʻe kulu microfluidic WGM
i loko o ka ʻāpana microfluidic, ʻoi aku hoʻi no ka kulu i loko o ka ʻaila (droplet in-oil), ma muli o nā ʻano o ka ʻili o ka ʻili, no ke anawaena o nā ʻumi a i ʻole nā haneli o nā microns, e hoʻokuʻu ʻia i loko o ka ʻaila, e hana ana i kahi sphere kokoke i ka hemolele. Ma o ka hoʻonui ʻana o ka index refractive, ʻo ka kulu ponoʻī he resonator spherical kūpono me kahi kumu maikaʻi ma mua o 108. Hōʻalo pū ia i ka pilikia o ka mahu ʻana i loko o ka ʻaila. No nā kulu nui, e "noho" lākou ma nā paia ʻaoʻao luna a i ʻole lalo ma muli o nā ʻokoʻa density. Hiki i kēia ʻano kulu ke hoʻohana wale i ke ʻano hoʻonāukiuki lateral.
