Ubude bamaza amaninziumthombo wokukhanyakwiphepha elisicaba
chips Optical yindlela engenakuphepheka ukuqhubeka uMthetho Moore kaThixo, iye yaba yimvumelwano kwiziko lemfundo kunye nezoshishino, inokusombulula ngempumelelo isantya kunye neengxaki zokusetyenziswa kwamandla ezijongene chips elektroniki, kulindeleke ukuba kubhukuqe ikamva computing ezikrelekrele kunye ultra-high-speed.unxibelelwano lwamehlo. Kwiminyaka yakutshanje, impumelelo ebalulekileyo yetekhnoloji kwi-silicon-based photonics igxile kuphuhliso lwenqanaba le-chip microcavity soliton optical frequency Combs, ezinokuvelisa ii-combs ezivuleke ngokulinganayo ngokusebenzisa ii-microcavities zokukhanya. Ngenxa yeenzuzo zayo zokudityaniswa okuphezulu, i-spectrum ebanzi kunye nokuphindaphinda okuphindaphindiweyo, i-chip level microcavity soliton umthombo wokukhanya unokusetyenziswa kunxibelelwano olukhulu, i-spectroscopy,Iifotoni ze-microwave, umlinganiselo ochanekileyo kunye neminye imimandla. Ngokubanzi, ukusebenza kakuhle kokuguqulwa kwe-microcavity single soliton optical frequency comb ihlala inqunyulwa ziiparamitha ezifanelekileyo ze-optical microcavity. Ngaphantsi kwamandla athile ompompo, amandla okuphuma kwe-microcavity eyodwa ye-soliton optical comb isoloko ilinganiselwe. Ukuqaliswa kwenkqubo yokukhulisa i-optical yangaphandle kuya kuchaphazela ngokuqinisekileyo umlinganiselo we-signal-to-noise. Ke ngoko, iprofayili yembonakalo ecaba ye-microcavity soliton optical frequency comb iye yaba kukusukela le ntsimi.
Kutshanje, iqela lophando eSingapore lenze inkqubela phambili ebalulekileyo kwibala lemithombo yokukhanya enamaza amaninzi kumaphepha acaba. Iqela lophando liphuhlise i-chip optical microcavity kunye ne-flat, i-spectrum ebanzi kunye ne-zero dispersion, kwaye ipakishwe ngokufanelekileyo i-chip ye-optical kunye ne-edge coupling (ilahleko yokudibanisa ngaphantsi kwe-1 dB). Ngokusekwe kwi-chip ye-optical microcavity, impembelelo enamandla ye-thermo-optical kwi-microcavity ye-optical iyoyiswa yinkqubo yobugcisa yokupompa kabini, kunye nomthombo wokukhanya we-multi-wavelength kunye ne-flat spectral output. Ngenkqubo yokulawula impendulo, inkqubo yomthombo we-soliton ye-multi-wavelength inokusebenza ngokuzinzileyo ngaphezu kweeyure ze-8.
Ukukhutshwa kwe-spectral yomthombo wokukhanya malunga ne-trapezoidal, izinga lokuphindaphinda malunga ne-190 GHz, i-flat spectrum igubungela i-1470-1670 nm, i-flatness malunga ne-2.2 dBm (i-standard deviation), kunye noluhlu lwe-flat spectral luthatha i-70% yayo yonke. uluhlu lwe-spectral, olugubungela ibhendi ye-S+C+L+U. Iziphumo zophando zingasetyenziswa kwi-high-capacity optical interconnection kunye ne-high-dimensionalukubonaiinkqubo zekhompyutha. Umzekelo, kwinkqubo yokubonisa umthamo omkhulu wonxibelelwano olusekwe kumthombo we-microcavity soliton comb, iqela le-frequency comb elinomahluko omkhulu wamandla lijongene nengxaki ye-SNR ephantsi, ngelixa umthombo we-soliton onemveliso ye-flat spectral unokoyisa ngempumelelo le ngxaki kwaye uncede ukuphucula I-SNR kwi-parallel optical information processing, enokubaluleka kobunjineli obubalulekileyo.
Umsebenzi, onesihloko esithi "Flat soliton microcomb source," yapapashwa njengephepha eligubungelayo kwiSayensi ye-Opto-Electronic njengenxalenye ye "Digital and Intelligent Optics".
