Micro-nano photonics tsuas yog kev sib cuam tshuam ntawm lub teeb thiab teeb meem ntawm lub teeb thiab nws daim ntawv thov, kev tshuaj xyuas thiab kev pom. Micro-nano wavelength cuab yeej tuaj yeem txhim kho cov khoom siv sau photon, thiab nws yuav tsum muaj cov khoom siv ntsuas hluav taws xob rau hauv cov chips hluav taws xob me me. NANO-Deg Plasmonics yog ib qho chaw tshiab ntawm micro-nano phanonics, uas tsuas yog kawm txog kev sib cuam tshuam ntawm lub teeb thiab teeb meem hauv cov hlau nanostructures. Nws muaj cov yam ntxwv ntawm qhov loj me me, kev kub ceev thiab kov yeej cov tsoos txawv kev txwv. Nanoplasma-WaveGuide qauv qauv, uas muaj cov cwj pwm zoo tshaj plaws thiab cov khoom siv lim dej, kho qhov muag theej tawm, laser thiab lwm yam micro-nano optical. Optical Microcavities muab lub teeb rau thaj tsam me me thiab txhim kho kev cuam tshuam ntawm lub teeb thiab teeb meem. Yog li no, lub qhov muag microcavity nrog cov khoom zoo yog ib txoj hauv kev tseem ceeb ntawm qhov siab rhiab thiab kev kuaj pom.
WGM microcavity
Nyob rau hauv xyoo tsis ntev los no, kho qhov muag microcavity tau nyiam ntau vim nws cov ntawv thov zoo thiab muaj txujci txuj ci. Lub qhov muag microcavity feem ntau yog muaj lub log, microcolumn, microroring thiab lwm yam geometries. Nws yog hom morphologic yog resulment optical resonator. Lub teeb tsis nyob hauv microcavities tau pom zoo tag nrho ntawm lub microcavity interface, uas nyob rau hauv ib lub resonance hom hu ua whisfing gallery hom (wgm). Piv nrog lwm tus kho qhov muag resonators, microresonators muaj cov yam ntxwv ntawm qib Q (ntau dua 106), thiab tau yooj yim dua 106), thiab lwm yam. Thiab lwm yam. Nonlinear Action. Peb cov kev tshawb fawb lub hom phiaj yog nrhiav thiab kawm cov yam ntxwv ntawm cov qauv sib txawv thiab cov qauv morphologies sib txawv, thiab siv cov yam ntxwv tshiab. Kev tshawb fawb tseem ceeb muaj xws li: Kev Tshawb Nrhiav Kev Tshawb Fawb Txog Optical WGM, kev tshawb fawb fab, kev tshawb fawb ntawm cov microcavity, thiab lwm yam.
WGM Microhocavity Biochemical Tas
Hauv kev sim, plaub-kev txiav txim siab-xaj WGM hom M1 (Daim duab 1 (a)) tau siv rau kev ntsuas ntsuas. Piv nrog hom qis-xaj, qhov rhiab ntawm hom kev txiav txim siab tau zoo dua (Daim duab 1 (b)).
Daim duab 1. Resonance hom (a) ntawm cov microcapillary kab noj hniav thiab nws cov lus hais kom ua kom muaj zog index rhiab (b)
Tunable optical lim nrog siab Q tus nqi
Ua ntej, radial maj mam hloov cov microcavity microcavity yog ua tiav los ntawm kev sib txuas ntawm cov qauv loj txij li lub wavelength (daim duab 2 (a)). Lub tanable kev ua tau thiab lim bandwidth tau qhia hauv daim duab 2 (b) thiab (c). Ib qho ntxiv, cov cuab yeej tuaj yeem paub qhov muag tsis pom kev nrog kev pom zoo nrog cov khoom siv hluav taws xob ntu.
Daim Duab 2. Schematic Daim duab ntawm tunable optical lim (a), tunable kev ua tau zoo (b) thiab lim bandwidth (c)
WGM Microfluidic Poob Resonator
Hauv microfluidic nti, tshwj xeeb tshaj yog rau cov tee hauv cov roj (droplet hauv cov roj (cov cheeb tsam ntawm lub ntsej muag, rau ntau pua ntawm cov roj, tsim muaj yuav luag zoo meej kheej kheej. Los ntawm kev ua kom zoo ntawm kev ua kom nws tus kheej refackent nws tus kheej yog ib qho zoo tshaj plaws ntawm ntau tshaj 108. Nws kuj yog qhov teeb meem ntawm ntau tshaj 108. Rau cov mob loj loj, lawv yuav "zaum" ntawm sab saud lossis sab hauv phab ntsa vim qhov sib txawv. Hom kev ntsuas no tsuas yog siv hom kev ua kom zoo.
