Me ka hoʻomohala wikiwiki ʻana o ka ʻenehana hoʻonui ʻia (AR), nā aniani akamai, ma ke ʻano he mea lawe nui o ka ʻenehana AR, ke neʻe mālie nei mai ka manaʻo i ka ʻoiaʻiʻo. Eia nō naʻe, ke kū nei ka hoʻohana nui ʻana o nā aniani akamai i nā pilikia ʻenehana, ʻoi aku ka nui o ka ʻenehana hōʻike, ke kaumaha, ka wela, a me ka hana optical. I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka silicon carbide (SiC), ma ke ʻano he mea e puka mai nei, i nā ʻano hana semiconductor mana a me nā modula. Ke hele nei ʻo ia i loko o ke kahua aniani AR ma ke ʻano he kumu nui. ʻO ka index refractive kiʻekiʻe o Silicon carbide, nā waiwai hoʻoheheʻe wela maikaʻi loa, a me ka paʻakikī kiʻekiʻe, ma waena o nā hiʻohiʻona ʻē aʻe, e hōʻike ana i ka mana nui no ka hoʻohana ʻana i ka ʻenehana hōʻike, ka hoʻolālā māmā, a me ka hoʻopau wela o nā aniani AR. Hiki iā mākou ke hoʻolakoSiC wafer, he kuleana koʻikoʻi ia i ka hoʻomaikaʻi ʻana i kēia mau wahi. Ma lalo nei, e ʻimi mākou pehea e hiki ai i ka silicon carbide ke lawe mai i nā loli hoʻololi i nā aniani akamai mai nā ʻano o kāna mau waiwai, nā holomua ʻenehana, nā noi mākeke, a me nā mea e hiki mai ana.
Nā waiwai a me nā pono o ka Silicon Carbide
ʻO ka Silicon carbide kahi mea semiconductor bandgap ākea me nā waiwai maikaʻi loa e like me ka paʻakikī kiʻekiʻe, ka conductivity thermal kiʻekiʻe, a me kahi kuhikuhi refractive kiʻekiʻe. Hāʻawi kēia mau hiʻohiʻona i ka mana nui no ka hoʻohana ʻana i nā mea uila, nā mea optical, a me ka hoʻokele wela. Ma ke kahua o nā aniani akamai, ʻike nui ʻia nā pono o ka silicon carbide i nā ʻano aʻe:
Kiʻekiʻe Refractive Index: Silicon carbide he refractive index ma luna o 2.6, ʻoi aku ka kiʻekiʻe ma mua o nā mea kahiko e like me ka resin (1.51-1.74) a me ke aniani (1.5-1.9). ʻO ka helu helu refractive kiʻekiʻe, hiki i ka silicon carbide ke kāohi pono i ka hoʻolaha ʻana o ka māmā, e hōʻemi ana i ka nalowale o ka ikehu māmā, a laila e hoʻomaikaʻi ai i ka ʻōlinolino hōʻike a me ke kahua o ka nānā (FOV). No ka laʻana, hoʻohana nā aniani ʻo Meta's Orion AR i ka ʻenehana alakaʻi hawewe silicon carbide, e hoʻokō ana i kahi kahua ʻike 70-degere, ʻoi loa aku ma mua o ke kahua ʻike 40-degere o nā mea aniani kahiko.
ʻO ka hoʻoheheʻe wela maikaʻi loa: ʻO ka Silicon carbide he mau haneli mau manawa i ʻoi aku ka nui ma mua o ke aniani maʻamau, e hiki ai i ka hoʻokele wela wikiwiki. He mea koʻikoʻi ka hoʻopau ʻana i ka wela no nā aniani AR, ʻoi aku hoʻi i ka wā o nā hōʻike ʻālohilohi kiʻekiʻe a me ka hoʻohana lōʻihi. Hiki i nā lens carbide silikon ke hoʻololi koke i ka wela i hana ʻia e nā mea optical, e hoʻonui ai i ka paʻa a me ke ola o ka hāmeʻa. Hiki iā mākou ke hāʻawi iā SiC wafer e hōʻoiaʻiʻo i ka hoʻokele wela maikaʻi ma ia mau noi.
ʻO ka paʻakikī kiʻekiʻe a me ka pale ʻana: ʻO Silicon carbide kekahi o nā mea paʻakikī loa i ʻike ʻia, ʻelua wale nō i ke daimana. ʻO kēia ka mea i ʻoi aku ka pale ʻana o nā lens silicon carbide, kūpono no ka hoʻohana ʻana i kēlā me kēia lā. ʻO ka hoʻohālikelike, ʻoi aku ka maʻalahi o nā mea aniani a me ka resin i nā ʻōpala, e pili ana i ka ʻike mea hoʻohana.
Pānaʻi Anti-Rainbow: ʻO nā mea aniani kuʻuna i nā aniani AR e hana i kahi hopena anuenue, kahi e hōʻike ʻia ai ke kukui ambient mai ka ʻili alakaʻi nalu, e hana ana i nā kumu kukui kala. Hiki i ka Silicon carbide ke hoʻopau maikaʻi i kēia pilikia ma o ka hoʻonui ʻana i ka hoʻolālā grating, no laila e hoʻomaikaʻi ai i ka maikaʻi o ka hōʻike a me ka hoʻopau ʻana i ka hopena anuenue ma muli o ka noʻonoʻo ʻana o ke kukui ambient ma ka ʻili nalu.
ʻO nā ʻenehana ʻenehana o Silicon Carbide i nā aniani AR
I kēia mau makahiki i hala iho nei, ua hoʻokumu nui ʻia ka holomua ʻenehana o ka silicon carbide i nā aniani AR i ka hoʻomohala ʻana i nā lens hawewe diffraction. ʻO ke alakaʻi hawewe ʻokoʻa kahi ʻenehana hōʻikeʻike e hoʻohui i ke ʻano ʻokoʻa o ka mālamalama me nā hale alakaʻi nalu e hoʻolaha i nā kiʻi i hana ʻia e nā ʻāpana optical ma o ka paʻi ʻana o ka lens. Hoʻemi kēia i ka mānoanoa o ka lens, e nānā kokoke ana nā aniani AR i nā maka maka maʻamau.
I ʻOkakopa 2024, ua hoʻolauna ʻo Meta (Facebook ma mua) i ka hoʻohana ʻana i nā alakaʻi hawewe silicon carbide-etched i hui pū ʻia me nā microLEDs i kāna mau aniani Orion AR, e hoʻonā ana i nā bottlenecks kī i nā kula e like me ke kahua o ka nānā, ke kaumaha, a me nā mea kiʻi optical. Ua ʻōlelo ʻo Pascual Rivera, ka mea ʻepekema optical o Meta, ua hoʻololi loa ka ʻenehana carbide waveguide i ka maikaʻi o ka hōʻike ʻana o nā aniani AR, e hoʻololi ana i ka ʻike mai "nā wahi kukui anuenue like me disco-ball" i kahi "concert hall-like serene experience."
I Kekemapa 2024, ua hoʻomohala maikaʻi ʻo XINKEHUI i ka honua mua 12-inch high-purity semi-insulating silicon carbide one crystal substrate, e hōʻailona ana i kahi holomua nui ma ke kahua o nā substrates nui. ʻO kēia ʻenehana e hoʻolalelale i ka hoʻohana ʻana i ka silicon carbide i nā hihia hoʻohana hou e like me nā aniani AR a me nā wela wela. No ka laʻana, hiki i kahi wafer silicon carbide 12-inihi ke hana i 8-9 mau maka aniani AR, e hoʻomaikaʻi nui ana i ka hana hana. Hiki iā mākou ke hāʻawi iā SiC wafer e kākoʻo i nā noi i ka ʻoihana aniani AR.
I kēia mau lā, ua hui pū ʻo XINKEHUI i ka mea hoʻolako silicon carbide substrate me ka micro-nano optoelectronic device company MOD MICRO-NANO e hoʻokumu i kahi ʻoihana hui e pili ana i ka hoʻomohala ʻana a me ka hoʻolaha mākeke o AR diffraction waveguide lens technology. ʻO XINKEHUI, me kona ʻike loea i nā substrates silicon carbide, e hāʻawi i nā substrates kiʻekiʻe no MOD MICRO-NANO, e hoʻohana i kāna mau pono i ka ʻenehana optical micro-nano a me ka hoʻoili ʻana o ka hawewe AR no ka hoʻonui ʻana i ka hana o nā alakaʻi nalu diffraction. Manaʻo ʻia kēia hui pū ʻana e hoʻolalelale i nā holomua ʻenehana i nā aniani AR, e hāpai ana i ka neʻe ʻana o ka ʻoihana i ka hana kiʻekiʻe a me nā hoʻolālā māmā.
Ma ka hōʻike 2025 SPIE AR|VR|MR, ua hōʻike ʻo MOD MICRO-NANO i kāna mau lens aniani silicon carbide AR, ʻo ke kaupaona ʻana he 2.7 grams wale nō a me ka mānoanoa o 0.55 millimeters wale nō, ʻoi aku ka māmā ma mua o nā makaaniani maʻamau, e hāʻawi ana i nā mea hoʻohana i kahi ʻike ʻike ʻike ʻole, e loaʻa ana i kahi hoʻolālā "māmā".
Nā hihia noi o Silicon Carbide i nā aniani AR
Ma ke kaʻina hana o nā alakaʻi nalu karbide silika, ua lanakila ka hui o Meta i nā pilikia o ka ʻenehana etching slanted. Ua wehewehe ka luna noiʻi ʻo Nihar Mohanty, ʻo ka slanted etching kahi ʻenehana kuʻuna kuʻuna ʻole e hoʻopaʻa i nā laina ma kahi kihi i hoʻopaʻa ʻia e hoʻomaikaʻi i ka hoʻopili māmā a me ka pono decoupling. Ua hoʻokumu kēia holomua i ke kumu no ka hoʻokomo nui ʻana o ka silicon carbide i nā aniani AR.
ʻO nā aniani ʻo Meta's Orion AR he palapala noi no ka ʻenehana carbide silicon ma AR. Ma ka hoʻohana ʻana i ka ʻenehana alakaʻi hawewe silicon carbide, loaʻa ʻo Orion i kahi kahua ʻike 70-degere a hoʻoponopono pono i nā pilikia e like me ka ghosting a me ka hopena anuenue.
Ua ʻike ʻo Giuseppe Carafiore, ke alakaʻi ʻenehana waveguide o Meta, ʻo ke kiʻekiʻe refractive index o ka silicon carbide a me ka conductivity thermal i mea kūpono no nā aniani AR. Ma hope o ke koho ʻana i ka mea, ʻo ka luʻi hou aʻe ʻo ka hoʻomohala ʻana i ke alakaʻi nalu, ʻo ia hoʻi ke kaʻina slanted etching no ka grating. Ua wehewehe ʻo Carafiore, ʻo ka grating, nona ke kuleana no ka hoʻopili ʻana i ka mālamalama i loko a i waho o ka lens, pono e hoʻohana i ka slanted etching. ʻAʻole i hoʻonohonoho pono ʻia nā laina i kālai ʻia akā ua puʻunaue ʻia ma kahi kihi iclined. Ua hoʻohui ʻo Nihar Mohanty ʻo lākou ka hui mua o ka honua e hoʻokō pololei i ka slanted etching ma nā polokalamu. Ma 2019, ua kūkulu ʻo Nihar Mohanty a me kāna hui i kahi laina hana hoʻolaʻa. Ma mua o kēlā, ʻaʻohe mea i loaʻa no ke kālai ʻana i nā alakaʻi nalu carbide silika, ʻaʻole hiki ke ʻenehana ma waho o ka lab.
ʻO nā pilikia a me nā manaʻo e hiki mai ana o Silicon Carbide
ʻOiai ke hōʻike nei ka silicon carbide i ka mana nui i nā aniani AR, ke kū nei kāna noi i kekahi mau pilikia. I kēia manawa, ʻoi aku ke kumu kūʻai o ka silicon carbide ma muli o ka lohi o ka ulu ʻana a me ka hana paʻakikī. No ka laʻana, hoʻokahi lens silicon carbide no nā aniani ʻo Meta's Orion AR ke kumu kūʻai ma kahi o $1,000, he mea paʻakikī ke hoʻokō i nā pono o ka mākeke mea kūʻai. Eia nō naʻe, me ka ulu wikiwiki ʻana o ka ʻoihana kaʻa uila, ke emi mālie nei ke kumukūʻai o ka silicon carbide. Eia kekahi, ʻo ka hoʻomohala ʻana i nā substrates nui (e like me nā wafers 12-inch) e hoʻoikaika hou i ka hoʻemi ʻana i ke kumukūʻai a me ka hoʻomaikaʻi maikaʻi ʻana.
ʻO ka paʻakikī kiʻekiʻe o ka silicon carbide ka mea paʻakikī i ka hana ʻana, ʻo ia hoʻi ma ka hana ʻana i ka micro-nano structure fabrication, e alakaʻi ana i nā kumukūʻai haʻahaʻa. I ka wā e hiki mai ana, me ka launa pū ʻana ma waena o nā mea hoʻolako substrate silicon carbide a me nā mea hana micro-nano optical, ua manaʻo ʻia e hoʻoholo ʻia kēia pilikia. ʻO ka hoʻohana ʻana o Silicon carbide i nā aniani AR aia nō i kona wā mua, e koi ana i nā ʻoihana hou aʻe e hoʻopukapuka kālā i ka noiʻi silicon carbide optical-grade a me ka hoʻomohala ʻana i nā lako. Manaʻo ka hui o Meta i nā mea hana ʻē aʻe e hoʻomaka i ka hoʻomohala ʻana i kā lākou mau lako ponoʻī, ʻoiai ʻoi aku ka nui o nā ʻoihana e hoʻokomo i ka noiʻi a me nā lako hana silicon carbide optical-grade, ʻoi aku ka ikaika o ka mea kūʻai aku-grade AR glasses ecosystem.
Ka hopena
ʻO ka Silicon carbide, me kona kiʻekiʻe refractive index, maikaʻi loa ka wela, a me ka paʻakikī kiʻekiʻe, ke lilo nei ia i mea koʻikoʻi ma ke kahua o nā aniani AR. Mai ka hui pū ʻana ma waena o XINKEHUI a me MOD MICRO-NANO a hiki i ka hoʻohana kūleʻa ʻana o ka carbide silicon i nā aniani ʻo Orion AR o Meta, ua hōʻike piha ʻia ka hiki o ka silicon carbide i nā aniani akamai. ʻOiai nā paʻakikī e like me ke kumu kūʻai a me nā pilikia ʻenehana, i ka wā e ulu ai ke kaulahao ʻoihana a hoʻomau ka ʻenehana i mua, manaʻo ʻia ka silicon carbide e ʻālohilohi i ke kahua aniani AR, e hoʻokele ana i nā aniani akamai i ka hana kiʻekiʻe, ʻoi aku ka māmā, a me ka hoʻohana ʻana. I ka wā e hiki mai ana, hiki i ka silicon carbide ke lilo i mea koʻikoʻi i ka ʻoihana AR, e hoʻomaka ana i kahi au hou o nā aniani akamai.
ʻAʻole i kaupalena ʻia ka hiki o ka silicon carbide i nā aniani AR; ʻO kāna mau noi ʻoihana cross-industry i ka uila a me nā photonics e hōʻike ana i nā manaʻo nui. No ka laʻana, ke ʻimi ikaika ʻia nei ka hoʻohana ʻana o ka silicon carbide i ka quantum computing a me nā mea uila uila mana kiʻekiʻe. Ke holomua nei ka ʻenehana a me ka emi ʻana o nā kumukūʻai, manaʻo ʻia ka silicon carbide e pāʻani i kahi hana koʻikoʻi i nā kula hou aku, e wikiwiki ana i ka hoʻomohala ʻana i nā ʻoihana pili. Hiki iā mākou ke hāʻawi iā SiC wafer no nā noi like ʻole, e kākoʻo ana i nā holomua ma ka ʻenehana AR a ma waho.
