Gwero la kuwala kwa mafunde ambiri pa pepala lathyathyathya

Kutalika kwa mafunde ambirigwero la kuwalapa pepala lathyathyathya

Ma chips optical ndi njira yosapeŵeka yopitirizira lamulo la Moore, lakhala lingaliro la akatswiri ndi mafakitale, lingathe kuthetsa mavuto a liwiro ndi kugwiritsa ntchito mphamvu omwe amakumana nawo ma chips amagetsi, ndipo likuyembekezeka kusokoneza tsogolo la makompyuta anzeru komanso liwiro lapamwamba kwambiri.kulankhulana kwa kuwalaM'zaka zaposachedwapa, kupita patsogolo kwakukulu kwaukadaulo mu ma photonics opangidwa ndi silicon kumayang'ana kwambiri pakupanga ma chip level microcavity soliton optical frequency combs, omwe amatha kupanga ma frequency combs okhala ndi malo ofanana kudzera mu ma microcavities optical. Chifukwa cha ubwino wake wophatikizana kwambiri, wide spectrum komanso high repetition frequency, chip level microcavity soliton light source ili ndi ntchito zomwe zingagwiritsidwe ntchito polumikizana ndi anthu ambiri, spectroscopy,zithunzi za microwave, muyeso wolondola ndi madera ena. Kawirikawiri, mphamvu yosinthira ya microcavity single soliton optical frequency comb nthawi zambiri imachepetsedwa ndi magawo oyenera a microcavity yowoneka bwino. Pansi pa mphamvu inayake ya pampu, mphamvu yotulutsa ya microcavity single soliton optical frequency comb nthawi zambiri imakhala yochepa. Kuyambitsa kwa external optical amplification system kudzakhudza mosakayikira chiŵerengero cha chizindikiro-mpaka-phokoso. Chifukwa chake, mawonekedwe a flat spectral a microcavity soliton optical frequency comb akhala kufunafuna kwa mundawu.

Posachedwapa, gulu lofufuza ku Singapore lapita patsogolo kwambiri pankhani ya magwero a kuwala kwa mafunde ambiri pa mapepala athyathyathya. Gulu lofufuza linapanga chip ya optical microcavity yokhala ndi spektroniki yopapatiza, yotakata komanso yofalikira pafupifupi zero, ndipo linayika bwino chip ya optical ndi coupling ya m'mphepete (kutayika kwa coupling kochepera 1 dB). Kutengera chip ya optical microcavity, mphamvu yamphamvu ya thermo-optical mu optical microcavity imagonjetsedwa ndi njira yaukadaulo yopopera kawiri, ndipo gwero la kuwala la mafunde ambiri lomwe lili ndi flat spectral output limapezeka. Kudzera mu dongosolo lowongolera mayankho, dongosolo la magwero la multi-wavelength soliton limatha kugwira ntchito mokhazikika kwa maola opitilira 8.

Mphamvu ya kuwala kwa spectral ndi pafupifupi trapezoidal, kubwerezabwereza kwake ndi pafupifupi 190 GHz, flat spectrum imaphimba 1470-1670 nm, flatness ndi pafupifupi 2.2 dBm (standard deviation), ndipo flat spectral imatenga 70% ya spectral yonse, ikuphimba gulu la S+C+L+U. Zotsatira za kafukufukuyu zingagwiritsidwe ntchito pa kulumikizana kwa kuwala kwamphamvu komanso kwamphamvu kwambiri.kuwalamakina owerengera. Mwachitsanzo, mu dongosolo lowonetsera kulumikizana kwakukulu lomwe limagwiritsa ntchito gwero la microcavity soliton comb, gulu la ma frequency comb lomwe lili ndi kusiyana kwakukulu kwa mphamvu limayang'anizana ndi vuto la SNR yochepa, pomwe gwero la soliton lomwe lili ndi flat spectral output lingathe kuthetsa vutoli bwino ndikuthandizira kukonza SNR mu njira yolumikizirana yazidziwitso za optical, yomwe ili ndi kufunika kofunikira kwaukadaulo.

Ntchitoyi, yotchedwa “Flat soliton microcomb source,” inasindikizidwa ngati pepala loyamba mu Opto-Electronic Science monga gawo la nkhani ya “Digital and Intelligent Optics”.
