Kumu kukui multiwavelength ma ka pepa pālahalaha

Ka lōʻihi o ka nalukumu kukuima ka pepa pālahalaha

ʻO nā ʻāpana optical ke ala hiki ʻole ke pale ʻia e hoʻomau i ke kānāwai o Moore, ua lilo i ʻaelike o ka ʻoihana kula a me ka ʻoihana, hiki iā ia ke hoʻoponopono pono i ka wikiwiki a me nā pilikia hoʻohana mana i kū i nā ʻāpana uila, e manaʻo ʻia e hoʻokahuli i ka wā e hiki mai ana o ka helu akamai a me ka wikiwiki loa.kamaʻilio ʻike makaI nā makahiki i hala iho nei, ua hoʻokumu ʻia kahi holomua ʻenehana koʻikoʻi i ka photonics silicon-based i ka hoʻomohala ʻana o nā chip level microcavity soliton optical frequency combs, hiki ke hoʻopuka i nā frequency combs i hoʻokaʻawale like ʻia ma o nā microcavities optical. Ma muli o kona mau pono o ka hoʻohui kiʻekiʻe, ka spectrum ākea a me ke alapine hana hou kiʻekiʻe, loaʻa i nā kumu kukui chip level microcavity soliton nā noi kūpono i ke kamaʻilio nui ʻana, spectroscopy,nā photonics microwave, ke ana pololei a me nā kahua ʻē aʻe. Ma keʻano laulā, ʻo ka pono o ka hoʻololi ʻana o ka microcavity single soliton optical frequency comb e kaupalena pinepine ʻia e nā palena pili o ka microcavity optical. Ma lalo o kahi mana pamu kikoʻī, ua kaupalena pinepine ʻia ka mana hoʻopuka o ka microcavity single soliton optical frequency comb. ʻO ka hoʻolauna ʻana o ka ʻōnaehana hoʻonui optical waho e hoʻopilikia mau i ka ratio signal-to-noise. No laila, ua lilo ka ʻaoʻao spectral pālahalaha o ka microcavity soliton optical frequency comb i mea e alualu ai i kēia kahua.

I kēia mau lā aku nei, ua holomua nui kahi hui noiʻi ma Singapore ma ke kahua o nā kumu kukui multi-wavelength ma nā pepa pālahalaha. Ua hoʻomohala ka hui noiʻi i kahi chip microcavity optical me kahi spectrum pālahalaha a kokoke i ka zero dispersion, a ua hoʻopili pono i ka chip optical me kahi coupling edge (coupling loss emi ma mua o 1 dB). Ma muli o ka chip microcavity optical, ua lanakila ka hopena thermo-optical ikaika i loko o ka microcavity optical e ka hoʻolālā loea o ka pumping pālua, a ua hoʻokō ʻia ke kumu kukui multi-wavelength me ka hopena spectral pālahalaha. Ma o ka ʻōnaehana hoʻomalu feedback, hiki i ka ʻōnaehana kumu soliton multi-wavelength ke hana paʻa no nā hola he 8 a ʻoi.

ʻO ka puka spectral o ke kumu kukui he trapezoidal paha, ʻo ka helu hana hou ma kahi o 190 GHz, uhi ka spectrum pālahalaha i 1470-1670 nm, ʻo ka flatness ma kahi o 2.2 dBm (maʻamau deviation), a noho ka laulā spectral pālahalaha i 70% o ka laulā spectral holoʻokoʻa, e uhi ana i ka hui S+C+L+U. Hiki ke hoʻohana ʻia nā hopena noiʻi i ka hoʻopili optical kiʻekiʻe a me nā dimensional kiʻekiʻe.ʻike makanā ʻōnaehana kamepiula. No ka laʻana, ma ka ʻōnaehana hōʻike kamaʻilio nui-mana e pili ana i ke kumu microcavity soliton comb, ʻo ka hui alapine (frequency comb) me ka ʻokoʻa ikehu nui e kū nei i ka pilikia o ka SNR haʻahaʻa, ʻoiai ʻo ke kumu soliton me ka hoʻopuka spectral pālahalaha hiki ke lanakila maikaʻi i kēia pilikia a kōkua i ka hoʻomaikaʻi ʻana i ka SNR i ka hana ʻike optical parallel, kahi mea nui i ka ʻenekinia.

Ua paʻi ʻia ka hana, i kapa ʻia ʻo "Flat soliton microcomb source," ma ke ʻano he pepa uhi ma Opto-Electronic Science ma ke ʻano he ʻāpana o ka puke "Digital and Intelligent Optics".
