Gwero la kuwala kwa Multiwavelength pa pepala lathyathyathya

Multiwavelengthgwero lowalapa pepala lathyathyathya

Kuwala tchipisi ndi njira yosalephereka kupitiriza Chilamulo Moore a, wakhala mgwirizano wa maphunziro ndi mafakitale, akhoza bwino kuthetsa liwiro ndi mphamvu mowa mavuto anakumana ndi tchipisi pakompyuta, akuyembekezeka kusokoneza tsogolo la kompyuta wanzeru ndi kopitilira muyeso-mkulu-liwiro.kulumikizana kwamaso. M'zaka zaposachedwa, ukadaulo wofunikira kwambiri pazithunzithunzi za silicon-based photonics umayang'ana kwambiri pakukula kwa chip level microcavity soliton optical frequency zisa, zomwe zimatha kupanga zisa zapawiri zofananira kudzera mu ma microcavities owoneka. Chifukwa cha zabwino zake zophatikizika kwambiri, mawonekedwe owoneka bwino komanso kubwereza pafupipafupi, gwero la kuwala kwa chip level microcavity soliton limatha kugwiritsa ntchito kulumikizana kwakukulu, ma spectroscopy,microwave photonics, kuyeza kolondola ndi magawo ena. Nthawi zambiri, kutembenuka kwamphamvu kwa microcavity single soliton optical frequency chisa nthawi zambiri kumakhala kochepa ndi magawo ofunikira a optical microcavity. Pansi pa mphamvu ya mpope, mphamvu yotulutsa ya microcavity single soliton optical frequency chisa nthawi zambiri imakhala yochepa. Kukhazikitsidwa kwa mawonekedwe akunja okulitsa mawonekedwe kudzakhudza chiŵerengero cha ma signal-to-noise. Choncho, lathyathyathya sipekitiramu mbiri ya microcavity soliton kuwala pafupipafupi chisa wakhala kufunafuna munda.

Posachedwapa, gulu lofufuza ku Singapore lapita patsogolo kwambiri pazambiri zowunikira mafunde ambiri pamapepala athyathyathya. Gulu lofufuzalo linapanga chipangizo chopangidwa ndi kuwala kwa microcavity chokhala ndi mawonekedwe osalala, otakata komanso pafupi ndi zero kubalalitsidwa, ndikuyika bwino chipangizocho ndi cholumikizira m'mphepete (kutayika kolumikizana kosakwana 1 dB). Kutengera chipangizo cha optical microcavity, mphamvu yamphamvu ya thermo-optical mu optical microcavity imagonjetsedwa ndi njira yaukadaulo ya kupopera kawiri, ndipo gwero la kuwala kokhala ndi mawonekedwe owoneka bwino limakwaniritsidwa. Kudzera pamakina owongolera mayankho, ma multi-wavelength soliton source system amatha kugwira ntchito mokhazikika kwa maola opitilira 8.

Kutulutsa kowoneka bwino kwa gwero la kuwala kuli pafupifupi trapezoidal, kubwereza kubwereza kuli pafupifupi 190 GHz, mawonekedwe osalala amakwirira 1470-1670 nm, kusalala kwake kuli pafupifupi 2.2 dBm (kupotoka kokhazikika), ndipo mawonekedwe owoneka bwino amakhala 70% yonse. mtundu wa spectral, wophimba gulu la S+C+L+U. Zotsatira za kafukufuku zingagwiritsidwe ntchito polumikizana ndi mawonekedwe apamwamba komanso apamwamba kwambirikuwalamakina apakompyuta. Mwachitsanzo, mu njira yayikulu yolumikizirana yolumikizirana yochokera ku gwero la microcavity soliton chisa, gulu lachisa pafupipafupi lomwe lili ndi kusiyana kwakukulu kwamphamvu limayang'anizana ndi vuto la otsika SNR, pomwe gwero la soliton lomwe lili ndi mawonekedwe owoneka bwino amatha kuthana ndi vutoli ndikuthandizira kukonza SNR mu parallel optical information processing, yomwe ili ndi kufunikira kwa uinjiniya.

Ntchitoyi, yotchedwa "Flat soliton microcomb source," idasindikizidwa ngati chivundikiro cha Opto-Electronic Science monga gawo la "Digital and Intelligent Optics".
