Muva nje ufunde e-University of Science neTechnology of China, i-University of Guo Guangcan Academian Team Professional Chuuncy contrect metha, ukufezekisa ukulinganiselwa kokuphindaphindwa kwe-wavency (Khz). Okutholakele kwashicilelwa ekuxhumaneni kwemvelo.
I-Soliton Microcombs isuselwa kuma-microcavities aptical idonsele intshisekelo enkulu yocwaningo emikhakheni yokunemba ama-spectroscopy namawashi abonakalayo. Kodwa-ke, ngenxa yethonya lomsindo wezemvelo nowe-laser kanye nemiphumela eyengeziwe engajwayelekile ye-microcavity, ukuqina kwe-soliton microcomm kukhawulelwe kakhulu, okuba yisithiyo esikhulu ekusetshenzisweni okungokoqobo kwe-light level comb. Emsebenzini owedlule, ososayensi bazinza futhi balawula i-Optical Frequency Calm ngokulawula inkomba ebonakalayo yezinto ezibonakalayo noma i-geometry ye-microcavity ukufezekisa izimpendulo ze-microcavity ngasikhathi sinye, entula amandla okulawula okuzimele kanye nokuphindaphinda kwe-comb. Lokhu kunciphisa kakhulu ukusetshenziswa kwe-comb ephansi elula kwizimo ezisebenzayo zokunemba kwe-spectroscopy, izithombe ze-microwave, ukuhanjiswa kwe-optical, njll.
Ukuxazulula le nkinga, ithimba lokucwaninga lihlongoza indlela entsha yomzimba ukuze ifezeke umthetho ozimele wesikhathi sangempela semvamisa yeSikhungo kanye nemvamisa ekhompiyutha ye-Optical Frequency Calk. Ngokwethula izindlela ezimbili ezihlukene zokulawulwa kokulawulwa kwe-micro-cavity, iqembu lingalawula ngokuzimela ukusakazwa kwemiyalo ehlukene ye-micro-cavity, ukuze kufinyelelwe ngokuphelele ukulawula okugcwele kwezinyo lamazinyo we-Optical Frequency Calk. Lo mshini wokulawulwa kokuphangwa ukhona emhlabeni jikelele kuma-photomu ahlanganisiwe ahlanganisiwe afana ne-silicon nitride ne-lithium niobate, efundwe kabanzi.
Iqembu lokucwaninga lasebenzisa i-laser yokupompa kanye ne-laser elisizayo ekuziphatheni ngokuzimela izindlela zama-oda ahlukene we-microcavity yokuqaphela imvamisa yemodi yokupompa kanye nokulawulwa kokuzimela kwemvamisa yemvamisa yemvamisa. Kususelwa ku-Optical Hork, ithimba lokucwaninga libonise imvamisa esheshayo, ehlelekile yamafrimu wokuphikisana futhi ayisebenzisile ekulinganiseni okunembile kobude be-wave, ukukhombisa ukunemba kokulinganisa kwe-oda le-kilohertz kanye nekhono kanyekanye. Uma kuqhathaniswa nemiphumela yocwaningo lwangaphambilini, ukunemba kokulinganisa okutholakele yithimba lokucwaninga selifinyelele kuma-oda amathathu wokuthuthuka kobukhulu.
I-microcombs evuselelekayo ye-soliton ekhonjiswe kulo mphumela wokucwaninga lalela isisekelo sokwamukelwa kwezindleko eziphansi, amazinga okuvunyelwa kwama-chip ahlanganiswe ngokulinganisa, iwashi le-optical, spectroscopy kanye nokuxhumana.
