Ubude bamaza amaninziumthombo wokukhanyakwiphepha elisicaba
Iitships ze-optical ziyindlela engenakuphepheka yokuqhubeka noMthetho kaMoore, sele iyinto evunywa yingcali yezemfundo namashishini, inokusombulula ngempumelelo iingxaki zesantya kunye nokusetyenziswa kwamandla ezijongene neetships ze-elektroniki, kulindeleke ukuba zitshintshe ikamva lekhompyutha ekrelekrele kunye nesantya esiphezulu kakhulu.unxibelelwano lwe-opticalKwiminyaka yakutshanje, inkqubela phambili ebalulekileyo kwezobuchwepheshe kwi-photonics esekwe kwi-silicon igxile ekuphuhlisweni kwee-chip level microcavity soliton optical frequency combs, ezinokuvelisa ii-frequency combs ezibekwe ngokulinganayo nge-optical microcavities. Ngenxa yeenzuzo zayo zokuhlanganiswa okuphezulu, i-wide spectrum kunye ne-high repetition frequency, i-chip level microcavity soliton light source inezicelo ezinokubakho kunxibelelwano olukhulu, i-spectroscopy,ii-photonics ze-microwave, ukulinganisa ngokuchanekileyo kunye nezinye iindawo. Ngokubanzi, ukusebenza kakuhle kokuguqulwa kwe-microcavity single soliton optical frequency comb kudla ngokulinganiselwa ziiparameter ezifanelekileyo ze-optical microcavity. Phantsi kwamandla athile epompo, amandla okukhupha e-microcavity single soliton optical frequency comb adla ngokulinganiselwa. Ukungeniswa kwenkqubo yokukhulisa i-optical yangaphandle kuya kuchaphazela ngokuqinisekileyo umlinganiselo wesignali-kwingxolo. Ke ngoko, iprofayili ye-flat spectral ye-microcavity soliton optical frequency comb iye yaba yinto ekufunwa ngayo le ndawo.
Kutshanje, iqela lophando eSingapore lenze inkqubela phambili ebalulekileyo kwicandelo lemithombo yokukhanya ye-multi-wavelength kwiiflethi ezisicaba. Iqela lophando lenze i-optical microcavity chip ene-flat, broad spectrum kwaye iphantse ibe yi-zero dispersion, kwaye yapakisha i-optical chip ngokufanelekileyo nge-edge coupling (ukulahleka kwe-coupling ngaphantsi kwe-1 dB). Ngokusekelwe kwi-optical microcavity chip, isiphumo esinamandla se-thermo-optical kwi-optical microcavity soyiswa yi-technical scheme yokupompa kabini, kwaye umthombo wokukhanya we-multi-wavelength one-flat spectral output uyafezekiswa. Ngenkqubo yolawulo lwempendulo, inkqubo yomthombo we-multi-wavelength soliton ingasebenza ngokuzinzileyo kangangeeyure ezingaphezu kwe-8.
Isiphumo se-spectral somthombo wokukhanya simalunga ne-trapezoidal, izinga lokuphindaphinda limalunga ne-190 GHz, i-flat spectrum igubungela i-1470-1670 nm, i-flatness imalunga ne-2.2 dBm (ukuphambuka okuqhelekileyo), kwaye uluhlu lwe-flat spectral luthatha i-70% yoluhlu lonke lwe-spectral, lugubungela i-S+C+L+U band. Iziphumo zophando zingasetyenziswa kwi-high-capacity optical interconnection kunye ne-high-dimensional.i-opticaliinkqubo zekhompyutha. Umzekelo, kwinkqubo yokubonisa unxibelelwano olunomthamo omkhulu olusekelwe kumthombo we-microcavity soliton comb, iqela le-frequency comb elinomahluko omkhulu wamandla lijongene nengxaki ye-SNR ephantsi, ngelixa umthombo we-soliton one-flat spectral output unokoyisa ngempumelelo le ngxaki kwaye uncede ukuphucula i-SNR ekucutshungulweni kolwazi lwe-optical ngaxeshanye, olunentsingiselo ebalulekileyo yobunjineli.
Lo msebenzi, onesihloko esithi “Flat soliton microcomb source,” wapapashwa njengephepha elingaphambili kwi-Opto-Electronic Science njengenxalenye yolu shicilelo lwe-“Digital and Intelligent Optics”.
Umfanekiso 1. Iskimu sokuqonda umthombo wokukhanya onamaza amaninzi kwipleyiti ethe tyaba
