Olu phuhliso lubeke isiseko sokwamkelwa ngobuninzi kwe-silicon carbide kwiiglasi ze-AR.
Iiglasi ze-Orion AR zeMeta ziyindlela emele ubuchwepheshe be-silicon carbide kwi-AR. Ngokusebenzisa ubuchwepheshe be-silicon carbide waveguide, i-Orion ifikelela kwimbono ye-degree ezingama-70 kwaye ijongana ngempumelelo nemiba efana ne-ghosting kunye ne-rainbow effect.
UGiuseppe Carafiore, inkokheli yetekhnoloji ye-AR waveguide kaMeta, uqaphele ukuba i-silicon carbide ephezulu yokurhawuzelela kunye nokuqhuba kobushushu kwenza ukuba ibe yinto efanelekileyo kwiiglasi ze-AR. Emva kokukhetha izinto, umngeni olandelayo yayikukuphuhlisa i-waveguide, ngakumbi inkqubo yokurhawuzelela ethe tyaba ye-grating. UCarafiore uchaze ukuba i-grating, enoxanduva lokudibanisa ukukhanya ngaphakathi nangaphandle kwelensi, kufuneka isebenzise i-slanted etching. Imigca ethe tyaba ayilungelelaniswanga ngokuthe nkqo kodwa isasazwa kwi-engile etyebileyo. UNihar Mohanty wongeze ngelithi babeliqela lokuqala kwihlabathi liphela ukufezekisa i-slanted etching ngqo kwizixhobo. Ngo-2019, uNihar Mohanty kunye neqela lakhe bakhe umgca wemveliso ozinikeleyo. Ngaphambi koko, akukho zixhobo zazifumaneka zokurhawuzelela ii-waveguide ze-silicon carbide, kwaye ubuchwepheshe babungenakwenzeka ngaphandle kwelebhu.
