Yini ama-photonics micro-nano?

I-Micro-Nano Photonics ikakhulukazi ifunda umthetho wokuxhumana phakathi kokukhanya kanye nendaba e-Micro ne-Nano Scale kanye nohlelo lokusebenza lwayo esizukulwaneni esikhanyayo, ukudluliselwa, ukutholwa, ukutholwa kanye nokuzwa. Amadivayisi we-Micro-Nano Photonics Sub-Wavelength angathuthukisa ngempumelelo izinga lokuhlanganiswa kwe-Photon, futhi kulindeleke ukuthi ahlanganise amadivaysi e-Photonic abe yi-chip encane ye-chip efana nama-chip e-elekthronikhi. I-Nano-Surfarlic Plasmonics iyinkambu entsha yeMicro-Nano Photonics, efunda ukuxhumana phakathi kokukhanya kanye nendaba kuma-nanostructures wensimbi. Inezici zobukhulu obuncane, isivinini esikhulu nokunqoba umkhawulo wokuphazamiseka kwendabuko. Isakhiwo se-Nanoplasma-WaveGuide, esinezici ezinhle zokulungiswa kwensimu yasendaweni kanye ne-resonance, yisisekelo sokuhlunga kwe-nanyo, i-wavelth division, i-laser kanye namanye amadivayisi we-micro-nano namanye amadivayisi we-micro-nano. I-Optical microcavities ibopha ukukhanya kwezifunda ezincane futhi ithuthukise kakhulu ukuxhumana phakathi kokukhanya nendaba. Ngakho-ke, i-microcavity ye-optical ene-high quality factor iyindlela ebalulekile yokuzwa okuphezulu kokuzwa nokutholwa.

I-WGM i-microcavity

Eminyakeni yamuva nje, i-Optical Microcavity idonsele ukunakwa okuningi ngenxa yokutholakala kwayo okuhle kohlelo lokusebenza kanye nokubaluleka kwesayensi. I-microcavity ye-optical ikakhulukazi iqukethe ama-microshere, i-microcolumn, i-microsing namanye ama-geometries. Kuluhlobo lomthengisi we-morphologic oxhomekeke. Amagagasi akhanyayo ezindabeni ezi-microcavities aboniswa ngokuphelele esibonakalayo se-microcavity, okuholela kwimodi yokubuyisa ebizwa nge-Whispering Gallery Mode (WGM). Uma kuqhathaniswa nabanye abaphostoli ababonakalayo, ama-Microssonators anezici zenani eliphakeme le-Q (enkulu kune-106), ivolumu yemodi ephansi, ivolumu elincane nokuhlanganiswa okulula, njll. Umgomo wethu wokucwaninga ukuthola nokutadisha izici zezakhiwo ezahlukahlukene kanye nama-morphologies ahlukene ama-microcavities, futhi asebenzise lezi zimpawu ezintsha. Izinkomba eziphambili zokucwaninga zifaka phakathi: Ukucwaninga kwezici ze-Optical of WGM I-microcavity, ukucwaninga kwe-FAFT ye-microcavity, ukucwaninga kwesicelo se-microcavity, njll.

I-WGM I-Microcavity Biochemical Sensing

Ekuhlolweni, imodi ye-oda le-oda eliphakeme le-WCM eliphakeme le-W1 (Fig. 1 (a)) lisetshenziselwa ukuzwakala. Uma kuqhathaniswa nemodi ye-Order-Order, ukuzwela kwemodi ye-oda eliphakeme kwathuthukiswa kakhulu (Fig. 1 (b)).

Isihlungi se-Tun Optical nge-QEAVE ephezulu ye-Q

Okokuqala, i-radial eshintsha kancane i-cylindrical microcavity iyakhishwa, bese kuthi i-waveghthth tuning ingatholakala ngokuhambisa isikhundla sokuhlanganisa ngokusekelwe kunqubo yosayizi wokwakheka kusukela ku-resonant wavength (a) (a)). Ukusebenza kwamathuba nokuhlunga i-bandwidth kukhonjiswa kuMfanekiso 2 (B) no (c). Ngaphezu kwalokho, idivaysi ingabona ukuthengiswa okubonakalayo okuzwakala ngokunemba kwe-nanometer.

I-WGM Microfluidic Drop Resonator

Ku-microfluidic chip, ikakhulukazi i-droplet emafutheni (amaconsi ase-oyela), ngenxa yezimpawu zengxabano engaphezulu, kububanzi bama-microns, izomiswa emafutheni, yakha i-oyela, yakha indawo ephelele. Ngokusebenzisa kahle kwenkomba esele, i-Droplet ngokwayo ingumthengisi ophelele we-spherical onesici sekhwalithi esingaphezu kwe-108. Kugwema futhi inkinga yokuhwamuka emafutheni. Amaconsi amakhulu, azohlala "ezindongeni eziseceleni ezingenhla noma ezingezansi ngenxa yokwehluka kobunzima. Lolu hlobo lwe-Droplet lungasebenzisa kuphela imodi yokuvuselela yamuva.
