N'October 2024, Meta (nke bụbu Facebook) webatara ojiji nke silicon carbide-etched waveguides jikọtara ya na microLEDs n'ime iko Orion AR ya, na-edozi mkpịsị mkpịsị mkpịsị ugodi na mpaghara dị ka nlele, ibu, na ngwa anya. Ọkà mmụta sayensị anya Meta bụ Pascual Rivera kwuru na teknụzụ silicon carbide waveguide gbanwere àgwà ngosipụta nke iko AR kpamkpam, na-agbanwe ahụmịhe ahụ site na “ntụpọ ọkụ disco-bọọlụ dị ka egwurugwu egwurugwu” gaa na “ahụmahụ ụlọ egwu dị ka ọmarịcha.”
Na Disemba 2024, XINKEHUI rụpụtara nke ọma n'ụwa mbụ 12-inch dị elu dị ọcha ọkara mkpuchi silicon carbide otu mkpụrụ kristal, na-aka akara nnukwu ọganiihu n'ọhịa nke mkpụrụ osisi buru ibu.
