Micro-nano photonics waxay inta badan barataa sharciga isdhexgalka iftiinka iyo walxaha ee cabbirka micro iyo nano iyo codsigeeda ku saabsan soo saarista iftiinka, gudbinta, nidaaminta, ogaanshaha iyo dareenka. Qalabka micro-nano photonics ee hirarka hoose waxay si wax ku ool ah u horumarin karaan heerka isdhexgalka photon, waxaana la filayaa inay ku daraan aaladaha photonic chip yar oo indhaha ah sida jajabyada elektarooniga ah. Plasmonics-ka dusha sare ee Nano waa goob cusub oo ah micro-nano photonics, kaas oo inta badan daraaseeya isdhexgalka ka dhexeeya iftiinka iyo walxaha ee nanostructures-ka birta. Waxay leedahay astaamaha cabbirka yar, xawaaraha sare iyo ka gudubka xadka kala-soocidda dhaqameed. Qaab-dhismeedka Nanoplasma-moveguide, kaas oo leh astaamo wanaagsan oo kor u qaadis maxalli ah iyo shaandhaynta resonance, waa saldhigga nano-filter, multiplexer qaybinta hirarka, badhanka indhaha, leysarka iyo aaladaha kale ee micro-nano optical. Microgodadka indhaha waxay ku koobaan iftiinka gobollo yaryar waxayna si weyn u xoojiyaan isdhexgalka iftiinka iyo walxaha. Sidaa darteed, microgodka indhaha oo leh qodob tayo sare leh waa hab muhiim ah oo lagu dareemo dareenka iyo ogaanshaha xasaasiyadda sare.
Godadka yar yar ee WGM
Sannadihii ugu dambeeyay, microcavity-ga indhaha ayaa soo jiitay dareen badan sababtoo ah awooddeeda weyn ee codsiga iyo muhiimadda cilmiyeed. Microcavity-ga indhaha ayaa inta badan ka kooban microsphere, microcolumn, microring iyo joomatari kale. Waa nooc ka mid ah resonator-ka indhaha ee ku tiirsan morphologic. Mowjadaha iftiinka ee microcavity-yada ayaa si buuxda uga muuqda is-dhexgalka microcavity-ga, taasoo keentay qaab resonance ah oo loo yaqaan qaabka gallery-ga ee whisping (WGM). Marka la barbardhigo resonators-yada kale ee indhaha, microresonators-ku waxay leeyihiin astaamaha qiimaha Q sare (ka weyn 106), mugga qaabka hoose, cabbirka yar iyo is-dhexgalka fudud, iwm., waxaana lagu dabaqay dareenka biochemical-ga ee xasaasiga sare leh, laser-ka heerka aadka u hooseeya iyo ficilka aan tooska ahayn. Hadafkayaga cilmi-baarista waa inaan helno oo aan baranno astaamaha qaab-dhismeedka kala duwan iyo qaababka kala duwan ee microcavities-ka, iyo inaan ku dabaqno sifooyinkan cusub. Tilmaamaha cilmi-baarista ugu weyn waxaa ka mid ah: cilmi-baarista astaamaha indhaha ee microcavity-ga WGM, cilmi-baarista soo saarista microcavity-ga, cilmi-baarista codsiga ee microcavity-ga, iwm.
Dareenka bayoolaji ee microcavity-ga WGM
Tijaabada, qaabka WGM ee afar-geesoodka sare leh M1 (Jaantuska 1(a)) ayaa loo isticmaalay cabbiraadda dareemaha. Marka la barbardhigo qaabka hoose, xasaasiyadda qaabka sare leh ayaa si weyn loo hagaajiyay (Jaantuska 1(b)).

Shaandhada indhaha ee la hagaajin karo oo leh qiimaha Q sare
Marka hore, microcavity-ga si tartiib tartiib ah u beddelaya radial-ka ayaa la soo saaraa, ka dibna hagaajinta hirarka waxaa lagu gaari karaa iyadoo si farsamo ahaan loo dhaqaajiyo booska isku-xidhka iyadoo lagu saleynayo mabda'a cabbirka qaabka tan iyo hirarka resonant-ka (Jaantuska 2 (a)). Waxqabadka la hagaajin karo iyo baaxadda shaandhaynta waxaa lagu muujiyay Jaantuska 2 (b) iyo (c). Intaa waxaa dheer, qalabku wuxuu xaqiijin karaa dareenka barokaca indhaha iyadoo la adeegsanayo saxnaanta hoose ee nanometer.

Qalabka hoos u dhiga dareeraha microfluidic ee WGM
jajabka microfluidic-ka, gaar ahaan dhibicda saliidda (dhibicda saliidda ku jirta), sababtoo ah sifooyinka xiisadda dusha sare, dhexroorka tobanaan ama xitaa boqolaal microns, waxaa lagu laalaadin doonaa saliidda, taasoo samaynaysa wareeg ku dhawaad ugu qumman. Iyada oo loo marayo hagaajinta tusmada refractive, dhibicda lafteedu waa resonator wareegsan oo qumman oo leh qodob tayo leh oo ka badan 108. Waxay sidoo kale ka fogaataa dhibaatada uumiga saliidda. Dhibcaha waaweyn, waxay ku "fadhiisan doonaan" darbiyada sare ama hoose ee dhinaca sababtoo ah kala duwanaanshaha cufnaanta. Noocan dhibicda ah wuxuu isticmaali karaa oo keliya qaabka kicinta dhinaca.
