Ko te nuinga o te wā, ko te ako a te micro-nano photonics te ture o te taunekeneke i waenga i te mārama me te matū i te tauine micro me te nano, me tōna whakamahinga i roto i te whakaputa mārama, te tuku, te whakahaere, te kimi me te rongo. Ka taea e ngā taputapu micro-nano photonics te whakapai ake i te taumata o te whakaurunga photon, ā, e tumanakohia ana ka whakauruhia ngā taputapu photonic ki roto i tētahi maramara whatu iti pērā i ngā maramara hiko. Ko te nano-mata plasmonics he mara hou o te micro-nano photonics, e ako ana i te taunekeneke i waenga i te mārama me te matū i roto i ngā hanganga nano whakarewa. He āhuatanga o te rahi iti, te tere teitei me te wikitoria i te rohe diffraction tuku iho. Ko te hanganga nanoplasma-waveguide, he pai te whakarei ake i te mara rohe me ngā āhuatanga tātari oro, ko te pūtake o te nano-tātari, te multiplexer wehenga roangaru, te pana whatu, te laser me ētahi atu taputapu whatu micro-nano. Ka herea e ngā microcavities whatu te mārama ki ngā rohe iti, ā, ka tino whakarei ake i te taunekeneke i waenga i te mārama me te matū. Nō reira, ko te microcavity whatu me te tauwehenga kounga teitei he huarahi nui ki te rongo me te kite i te tairongo teitei.
Te poka iti o te WGM
I ngā tau tata nei, kua nui te aro ki te moroiti whatu nā te mea he nui te kaha ki te whakamahi me te hiranga pūtaiao. Ko te moroiti whatu he mea hanga ki te moroiti, ki te pou moroiti, ki te mowhiti moroiti me ētahi atu āhuahanga. He momo whakaata whatu e whakawhirinaki ana ki te āhua. Ka whakaata katoatia ngā ngaru mārama i roto i ngā moroiti i te atanga moroiti, ka hua ake he aratau whakaata e kiia nei ko te aratau taiwhanga whispering (WGM). Ki te whakatauritea ki ētahi atu whakaata whatu, he āhuatanga ngā moroiti resonator o te uara Q teitei (neke atu i te 106), te rōrahi aratau iti, te rahi iti me te ngāwari ki te whakauru, me ētahi atu, ā, kua whakamahia ki te ine matū koiora tairongo teitei, te taiaho paepae tino iti me te mahi kore-raina. Ko tā mātou whāinga rangahau he kimi me te ako i ngā āhuatanga o ngā hanganga rerekē me ngā āhuahanga rerekē o ngā moroiti, me te whakamahi i ēnei āhuatanga hou. Ko ngā aronga rangahau matua ko: te rangahau āhuatanga whatu o te moroiti WGM, te rangahau hanga moroiti, te rangahau tono moroiti, me ētahi atu.
Te pūoko matū koiora o te poka iti WGM
I roto i te whakamātautau, i whakamahia te aratau WGM teitei-raupapa e whā M1 (Pikitia 1(a)) mō te ine ine. Ki te whakatauritea ki te aratau iti-raupapa, i tino pai ake te aro o te aratau teitei-raupapa (Pikitia 1(b)).

Tātari whatu ka taea te whakarerekē me te uara Q teitei
Tuatahi, ka unuhia te kōhao moroiti porotaka e āta huri haere ana, kātahi ka taea te whakatutuki i te whakatikatika roanga ngaru mā te neke ā-mīhini i te tūranga hononga i runga i te mātāpono o te rahi āhua mai i te roanga ngaru orooro (Pikitia 2 (a)). Kei te whakaatuhia te mahi whakatikatika me te whānui tātari i roto i te Pikitia 2 (b) me te (c). Hei tāpiri, ka taea e te taputapu te whakatutuki i te rongo nekehanga whatu me te tika iti iho i te nanometer.

Kaiwhakaoho maturuturu moroiti WGM
I roto i te maramara moroiti wai, inā koa mō te pata i roto i te hinu (pata i roto i te hinu), nā ngā āhuatanga o te taumahatanga mata, mō te diameter o ngā tekau, tae atu ki ngā rau maikoroni, ka iri i roto i te hinu, ka hanga he porowhita tata tino pai. Mā te arotau i te taupū whakaata, he tino pai te pata me te tauwehenga kounga neke atu i te 108. Ka karohia hoki te raruraru o te mimiti i roto i te hinu. Mō ngā pata nui, ka "noho" ki runga i ngā pakitara taha o runga, o raro rānei nā te rerekētanga o te mātotoru. Ka taea anake e tēnei momo pata te whakamahi i te aratau whakaoho taha.
