Kutshanje ufunde kwiDyunivesithi yeNzululwazi kunye neTekhnoloji yeChina, iYunivesithi yaseGuo Guongcan Dong Churlion yeZiko lokuLawulwa kweZiko loLuntu, kwaye isetyenziswa ngokulandelelana kwe-Superlical Waven, i-WaveToure iCouraction inyanzeliswa I-klohertz (khz). Iziphumo zapapashwa kunxibelelwano lwendalo.
I-mitton microcombs esekwe kwii-microcavies zokukhanya zitsalele umdla omkhulu uphando olukhulu kwicandelo le-scoctrascopy kunye neewotshi zewotshi. Nangona kunjalo, ngenxa yempembelelo yengxolo yendalo esingqongileyo kunye ne-laser kunye neziphumo ezongeziweyo ze-microcar, uzinzo kwi-mitton incinci, iba ngumqobo omkhulu ekusebenziseni inqanaba eliphantsi lomgangatho. Kumsebenzi odlulileyo, izazinzulu zizinza zaza zalawula i-RESFATA PROQUAT ngokulawula isalathiso semiba-nkqubela okanye i-geometri ye-microcavity yokufumana ingxelo yexeshana, elingenakukwazi ukuzimela ngokuzimeleyo kunye nokuphinda-phinda umjikelo. Oku kuthintela kakhulu ukusetyenziswa komgaqo ophantsi wokukhanya kwizigcawu ezisebenzayo ze-specroscopy, imifanekiso microwave yeefoto, i-themical themical, njl.
Ukusombulula le ngxaki, iqela lophando licebise indlela entsha yomzimba ukufezekisa uMmiselo wexeshana ozimeleyo wexesha leziko kunye nokuphindaphinda kwenziwa rhoqo kwi-REARQES. Ngokwazisa ngeendlela ezimbini zokulawula ukusasazeka kwe-micro-cavity, iqela elinokulawula ngokuzimela ukusasazeka kwee-odolo ze-micro-cavity, ukuze kufezekiswe ulawulo olupheleleyo lwezantya ezahlukeneyo ze-mpela. Le nkqubo yokusasaza indalo iphela kwiqonga elihlanganisiweyo le-Potoniic elahlukileyo elinjengeli-Silicon Nitride kunye neLithium Niobete, efundiswe ngokubanzi.
Iqela lophando lalisebenzisa i-pumpleng laser kunye ne-leser encedisayo ukuba ilawule ngokuzimeleyo kwiimowudi ze-microcavity ukufezekisa ukuzinza kwe-pumplates kunye ne-frequeting frequency. Ngokusekwe kumdibaniso we-optical, iqela lophando libonisa ngokukhawuleza, ukulawulwa kwenkqubo ye-freettiment kwaye isebenzise kwimilinganiselo echanekileyo ye-tilohertz kunye nesakhono sokulinganisa i-wavelengths ezininzi ngaxeshanye. Xa kuthelekiswa neziphumo zophando zangaphambili, ukuchaneka kwemilinganiselo okufunyenwe yiQela loPhando kufikelele kwii-odolo ezintathu zophuculo oluninzi.
I-microcombs ebonakalayo ebonakalayo iboniswe kolu phando ukubeka isiseko sokufezekiswa kweendleko zexabiso eliphantsi, ezihlanganisiweyo ze-Chip ezihlanganisiweyo, eziya kusetyenziswa kwi-SICRQUALS, eya kusetyenziswa kwiwotshi yokuchaneka, iwotshi yelogo, i-spectrascopy kunye nonxibelelwano.
