Itekhnoloji entsha yeIfoto ye-Silicon
I-Photon ye-Photon yezakhiwo zisetyenziselwa ukomeleza ukukhanya okukhanyayoIifoto zeSilicon
Iinkqubo ze-Potonic zifumana ingqungquthela kwizicelo ezininzi ezivelayo, kubandakanya nonxibelelwano oluphumayo, i-lidar ifihla kunye nokucinga kwezonyango. Nangona kunjalo, ukwanda kwamkeleka kwi-Potonics kwiZisombululo zobuNjineli kwiLimva kuxhomekeke kwiindleko zemvelisoIifoto, ethi kamva ixhomekeke kakhulu kuhlobo lwe-semicondcuctor esetyenziselwa loo njongo.
Ngokwesiko, i-silicon (i-Si) yayiyeyona i-Ubiquitious Semiconductor kwiShishini le-Electronics, kakhulu ukuze amashishini amaninzi akhule ngokujikelezileyo ezi zinto. Ngelishwa, u-Silt une-abs ebuthathaka ebuthathaka ye-UNEARD kwi-infrared ekufutshane (i-NIR) ye-wimicontund affer efana ne-Gallium Arsenide (Gas). Ngenxa yoku, i-GAAS kunye ne-ALTYS eyalelweyo iyachuma kwizicelo zepitotic kodwa azihambelani ne-therimoric ender-yensimo yensimo yensimo yensimo yensimo. Oku kukhokelele kwinyuko ebukhali kwiindleko zabo zokwenza.
Abaphandi baqulunqa indlela yokuyekisa kakhulu i-selicred yokufumana i-selicon, enokukhokelela ekunciphiseni kweendleko kwizixhobo ezisebenzayo ze-Petotoic, kunye neqela lophando lwe-UC Davis linguvulindlela. Kwiphepha labo lakutsha nje kwi-phetotoics ye-phetonics, babonisa okokuqala ngqalelo yovavanyo lwefoto yaseSilicon kunye nolwakhiwo lomphezulu we-nano, efezekisa ukuphuculwa komgangatho okhanyayo kunye ne-NaIi-v Iqela le-III-v Grouponturs. Umfanekiso wefoto iqulathe i-Microron-ipylight ipleyiti ibekwe kwindawo yokuthambisa, eneminwe "yeminwe" kwifashoni ye-fork nganye ukusuka kwintsimbi yoqhakamshelwano phezulu kwiplate yoqhakamshelwano. Ngokubalulekileyo, i-silicon yesilwanyana igcwaliswe yimingxunya ejikelezwe kwipateni yamaxesha ngamaxesha asebenza njengeendawo zokubamba zePhoton. Isakhiwo esipheleleyo sesixhobo sibangela ukukhanya okuqhelekileyo ukugoba phantse ngama-90 ° xa kubetha umphezulu, ivumela ukuba ikhulise i-SIP ye-SIN ngenqwelomoya. Ezi ndlela zokuhamba ze-Lately zinyusa ubude bokuhamba kancinci kwaye zicothise ngokufanelekileyo, zikhokelele ekusebenziseni okulula komcimbi kwaye ke kwandise ukufunxa.
Abaphandi baqhubela phambili ukuthoba kunye nokuhlalutya kwethiyori ukuya kuqonda ngcono iziphumo zezakhiwo zePhoton, kwaye ziqhube iimvavanyo ezininzi ezithelekisa iifoto kunye nazo. Bafumanise ukuba ukubanjwa kwe-photon kutyhilwe kuphuculo olubonakalayo kwinqanaba elibanzi le-nig kwi-wir shoctrum, ukuhlala ngaphezulu kwe-68% ngencopho ye-86%. Kufanelekile ukuba ukuthoba ukuba kwibhendi ye-infrared ekufuphi, i-acernged and of ye-Photon Phototeriute Pempleetector ngamaxesha amaninzi ngaphezulu kwe-silicon eqhelekileyo, ngaphezulu kwe-Gallium Arselium Arsenide. Ukongeza, nangona loyilo olucetywayo le-1μm ipleyiti ye-silicdon, i-imeyile ye-30 NM kunye ne-100 nm yezifilimili ezihambelana nee-CMOs ze-elektroniki zibonisa ukusebenza okufanayo.
Ngokubanzi, iziphumo zolu phononongo zibonisa isicwangciso esithembisayo sokuphucula ukusebenza kwe-silicoteeteateateateeteeded esekwe kwi-setoconics kwizicelo ezivelayo. Ukufudukela okuphezulu kunokufezekiswa nakwiindawo ze-ultra ezinqamlezileyo, kwaye i-parasitic yeparasical yesephathe inokugcinwa, ebaluleke kakhulu kwiinkqubo ezihamba-hlula. Ukongeza, indlela ecetywayo iyahambelana neenkqubo ze-CMOs zanamhlanje kwaye ke inakho ukuguqula indlela i-optoelectrouction idityaniswe kwiisekethe zemveli. Oku, oko, kungayivula indlela yokutsiba okukhulu kweenethiwekhi ze-loricas ezifikelelekayo kunye nokucinga.
