N'ọnwa Ọktoba afọ 2024, Meta (nke bụbu Facebook) webatara ojiji nke silicon carbide-etched waveguides jikọtara ya na microLEDs na iko Orion AR ya, na-edozi nsogbu ndị dị mkpa n'ọhịa dịka ubi nke anya, ibu, na ihe ochie anya. Ọkà mmụta sayensị anya nke Meta bụ Pascual Rivera kwuru na teknụzụ silicon carbide waveguide gbanwere àgwà ngosipụta nke iko AR kpamkpam, na-agbanwe ahụmịhe ahụ site na "ebe ìhè dị ka disko-ball" gaa na "ahụmịhe dị jụụ dị ka ụlọ egwu."
Na Disemba 2024, XINKEHUI mepụtara ihe mkpuchi kristal silicon carbide nke mbụ dị sentimita iri na abụọ nke dị ọcha n'ụwa, nke na-egosi nnukwu ọganihu n'ọhịa nke ihe mkpuchi nnukwu nha.
