Mea ʻike kiʻi silicon kipi (mea ʻike kiʻi Si)

Hoʻokahuli aupunimea ʻike kiʻi silicon（Mea ʻike kiʻi Si）

Mea ʻike kiʻi silika holoʻokoʻa kipi（Mea ʻike kiʻi Si）, ka hana ma mua o ke kuʻuna

Me ka paʻakikī o nā hiʻohiʻona akamai artificial a me nā pūnaewele neural hohonu, ua kau nā hui helu i nā koi kiʻekiʻe ma ka kamaʻilio pūnaewele ma waena o nā mea hana, nā node hoʻomanaʻo a me nā kikowaena helu. Eia nō naʻe, ʻaʻole hiki i nā pūnaewele maʻamau ma-chip a me nā pūnaewele inter-chip e pili ana i nā pilina uila ke hoʻokō i ka koi e ulu ana no ka bandwidth, latency a me ka hoʻohana ʻana i ka mana. I mea e hoʻoponopono ai i kēia bottleneck, ʻo ka ʻenehana interconnection optical me kona mamao hoʻoili lōʻihi, ka wikiwiki wikiwiki, nā pono pono o ka ikehu kiʻekiʻe, e lilo mālie i manaʻolana no ka hoʻomohala ʻana i ka wā e hiki mai ana. I waena o lākou, hōʻike ka ʻenehana photonic silicon e pili ana i ke kaʻina hana CMOS i ka hiki nui ma muli o kona hoʻohui kiʻekiʻe, ke kumukūʻai haʻahaʻa a me ka pololei o ka hana ʻana. Eia nō naʻe, ke kū nei ka hoʻokō ʻana o nā photodetectors hana kiʻekiʻe i nā pilikia he nui. ʻO ka maʻamau, pono nā photodetectors e hoʻohui i nā mea me kahi āpau band haiki, e like me germanium (Ge), e hoʻomaikaʻi i ka hana ʻike, akā alakaʻi pū kēia i nā kaʻina hana hana paʻakikī, nā kumukūʻai kiʻekiʻe, a me nā hua erratic. Ua hoʻokō ka photodetector all-silicon i hoʻomohala ʻia e ka hui noiʻi i ka wikiwiki o ka hoʻoili ʻikepili o 160 Gb/s no kēlā me kēia kahawai me ka hoʻohana ʻole ʻana i ka germanium, me ka bandwidth hoʻoili holoʻokoʻa o 1.28 Tb/s, ma o kahi hoʻolālā resonator dual-microring hou.

I kēia mau lā iho nei, ua paʻi kahi hui noiʻi hui ma ʻAmelika Hui Pū ʻIa i kahi noiʻi hou, e hoʻolaha ana ua hoʻomohala pono lākou i kahi photodiode avalanche silicon āpau (Mea ʻike kiʻi APD) chip. Loaʻa i kēia chip ka hana interface photoelectric wikiwiki loa a me ke kumu kūʻai haʻahaʻa, ka mea i manaʻo ʻia e hoʻokō i ka hoʻoili ʻikepili ma mua o 3.2 Tb i kekona i nā pūnaewele optical e hiki mai ana.

Ka holomua loea: hoʻolālā resonator microring pālua

Loaʻa pinepine i nā mea ʻike kiʻi kuʻuna nā kūʻē kūʻē ʻole ma waena o ka bandwidth a me ka pane ʻana. Ua hoʻomaha maikaʻi ka hui noiʻi i kēia kūʻē ʻana ma ka hoʻohana ʻana i kahi hoʻolālā resonator microring pālua a kāohi pono i ke kamaʻilio ʻana ma waena o nā kahawai. Hōʻike nā hopena hoʻokolohua i kamea ʻike kiʻi silika āpauhe pane A o 0.4 A/W, he au pouli e like me 1 nA, he bandwidth kiʻekiʻe o 40 GHz, a he crosstalk uila haʻahaʻa loa ma lalo o −50 dB. Ua like kēia hana me nā photodetectors kalepa o kēia manawa e pili ana i nā mea silicon-germanium a me III-V.

Ke nānā nei i ka wā e hiki mai ana: Ke Ala i ka hana hou i nā pūnaewele optical

ʻAʻole wale ka holomua o ka hoʻomohala ʻana o ka photodetector all-silicon i ʻoi aku ma mua o ka hopena kuʻuna i ka ʻenehana, akā ua hoʻokō pū kekahi i ka mālama kālā ma kahi o 40% o ke kumukūʻai, e hoʻomākaukau ana i ke ala no ka hoʻokō ʻana i nā pūnaewele optical wikiwiki a haʻahaʻa ke kumukūʻai i ka wā e hiki mai ana. Hoʻohālikelike piha ka ʻenehana me nā kaʻina hana CMOS e kū nei, he kiʻekiʻe loa ka hua a me ka hua, a manaʻo ʻia e lilo i ʻāpana maʻamau i ke kahua o ka ʻenehana photonics silicon i ka wā e hiki mai ana. I ka wā e hiki mai ana, hoʻolālā ka hui noiʻi e hoʻomau i ka hoʻomaikaʻi ʻana i ka hoʻolālā e hoʻomaikaʻi hou aku i ka helu absorption a me ka hana bandwidth o ka photodetector ma ka hoʻemi ʻana i nā ʻano doping a me ka hoʻomaikaʻi ʻana i nā kūlana implantation. I ka manawa like, e ʻimi pū ka noiʻi pehea e hiki ai ke hoʻopili ʻia kēia ʻenehana all-silicon i nā pūnaewele optical i nā hui AI hanauna e hiki mai ana e hoʻokō i ka bandwidth kiʻekiʻe, scalability a me ka pono o ka ikehu.
