Micro-nano Photonics ni iki?

Micro-nano Photonics yiga cyane cyane amategeko yimikoranire hagati yumucyo nibintu kurwego rwa micro na nano no kuyikoresha mugukora urumuri, kwanduza, kugenzura, gutahura no kumva. Micro-nano Photonics sub-wavelength ibikoresho birashobora kuzamura neza urwego rwo guhuza fotone, kandi biteganijwe ko izahuza ibikoresho bya fotonike mugace gato ka optique nka chip ya elegitoroniki. Nano-ubuso bwa plasmonike ni umurima mushya wa micro-nano Photonics, yiga cyane cyane imikoranire yumucyo nibintu mubintu bya nanostructures. Ifite ibiranga ubunini buto, umuvuduko mwinshi no gutsinda imipaka gakondo. Imiterere ya Nanoplasma-waveguide, ifite ibyiza byaho byongera umurima hamwe na resonance yo kuyungurura, ni ishingiro rya nano-muyunguruzi, kugabana umurongo wa multiplexer, optique, optique, laser nibindi bikoresho bya optique ya micro-nano. Microcavities optique ifata urumuri mukarere gato kandi ikazamura cyane imikoranire yumucyo nibintu. Kubwibyo, optique ya microcavity hamwe nibintu byujuje ubuziranenge ni inzira yingenzi yo kumva no kumva neza.

Microcavity ya WGM

Mu myaka yashize, microcavity optique yakwegereye abantu benshi bitewe nubushobozi bukomeye bwo gukoresha nubumenyi bwa siyanse. Microcavity optique igizwe ahanini na microse, microcolumn, microring hamwe na geometrie. Nubwoko bwa morphologique bushingiye kuri optique resonator. Imiraba yumucyo muri microcavities igaragarira neza kuri microcavity interface, bikavamo uburyo bwa resonance bwitwa whispering gallery mode (WGM). Ugereranije nizindi optique ya resonator, microresonator ifite ibiranga Q agaciro keza (karenze 106), ingano yuburyo buto, ingano ntoya no kwishyira hamwe byoroshye, nibindi, kandi byashyizwe mubikorwa-byunvikana cyane biochemical sensing, ultra-low limit laser na ibikorwa bidafite umurongo. Intego yacu yubushakashatsi nugushakisha no kwiga ibiranga imiterere itandukanye na morphologie zitandukanye za microcavities, no gushyira mubikorwa ibyo biranga bishya. Icyerekezo cyingenzi cyubushakashatsi kirimo: optique iranga ubushakashatsi bwa microcavity ya WGM, ubushakashatsi bwo guhimba microcavity, ubushakashatsi bwokoresha microcavity, nibindi.

WGM microcavity biochemical sensing

Mu igeragezwa, uburyo bune butondekanya cyane bwa WGM uburyo bwa M1 (FIG. 1 (a)) bwakoreshejwe mu gupima ibipimo. Ugereranije nuburyo buke bwo gutondekanya, ibyiyumvo byuburyo bwo hejuru byatejwe imbere cyane (FIG. 1 (b)).

Igishushanyo 1. Uburyo bwa rezonance (a) ya microcapillary cavity hamwe nuburinganire bwayo bwerekana (b)

Guhindura optiki muyunguruzi hamwe na Q agaciro gakomeye

Ubwa mbere, radiyo ihindura buhoro buhoro microcavitike ya silindrike ikururwa, hanyuma guhuza umurongo wumurongo birashobora kugerwaho hifashishijwe uburyo bwo kwimura imyanya ihuza hashingiwe ku ihame ryubunini bwimiterere kuva uburebure bwa resonant (Ishusho 2 (a)). Imikorere ihindagurika no kuyungurura umurongo byerekanwe mubishusho 2 (b) na (c). Mubyongeyeho, igikoresho gishobora kumenya optique yo kwimura ibyiyumvo hamwe na sub-nanometero neza.

WGM microfluidic yatonyanga resonator

muri chip ya microfluidic, cyane cyane ku gitonyanga cyamavuta (igitonyanga mu mavuta), kubera ibiranga impagarara zubuso, kuri diameter ya mirongo icumi cyangwa ndetse na microni amagana, bizahagarikwa mumavuta, bibe hafi urwego rutunganye. Binyuze mu kuzamura ibipimo ngenderwaho, igitonyanga ubwacyo ni rezoneri nziza cyane ifite ibintu byiza birenga 108. Irinda kandi ikibazo cyo guhumeka mumavuta. Kubitonyanga binini ugereranije, "bazicara" kurukuta rwo hejuru cyangwa hepfo kubera itandukaniro ryubwinshi. Ubu bwoko bwibitonyanga bushobora gukoresha gusa uburyo bwo kwishima.
