ʻO ka wā e hiki mai ananā mea hoʻololi ʻike uila
He kuleana koʻikoʻi ko nā modulators electro optic i nā ʻōnaehana optoelectronic hou, e pāʻani ana i kahi kuleana koʻikoʻi ma nā ʻano he nui mai ke kamaʻilio ʻana a i ka helu quantum ma o ka hoʻoponopono ʻana i nā waiwai o ka mālamalama. Kūkākūkā kēia pepa i ke kūlana o kēia manawa, ka holomua hou loa a me ka hoʻomohala ʻana o ka ʻenehana modulator electro optic i ka wā e hiki mai ana.
Kiʻi 1: Hoʻohālikelike hana o nā ʻano like ʻolemea hoʻololi ʻike makanā ʻenehana, me ka lithium niobate kiʻi lahilahi (TFLN), III-V electrical absorption modulators (EAM), silicon-based a me polymer modulators e pili ana i ka pohō hoʻokomo, bandwidth, hoʻohana mana, ka nui, a me ka hiki ke hana.
ʻO nā modulators electro optic kuʻuna i hoʻokumu ʻia i ka silicon a me ko lākou mau palena
ʻO nā modulators kukui photoelectric i hoʻokumu ʻia ma Silicon ke kumu o nā ʻōnaehana kamaʻilio optical no nā makahiki he nui. Ma muli o ka hopena hoʻolaha plasma, ua holomua nui kēlā mau mea hana i nā makahiki 25 i hala iho nei, e hoʻonui ana i nā helu hoʻoili ʻikepili ma ʻekolu mau kauoha o ka nui. Hiki i nā modulators i hoʻokumu ʻia ma ka silicon hou ke hoʻokō i ka modulation amplitude pulse 4-level (PAM4) a hiki i ka 224 Gb/s, a ʻoi aku ma mua o 300 Gb/s me ka modulation PAM8.
Eia nō naʻe, ke kū nei nā modulators i hoʻokumu ʻia i ka silicon i nā palena koʻikoʻi e pili ana i nā waiwai o nā mea. Ke koi nei nā transceivers optical i nā baud rates ma mua o 200+ Gbaud, paʻakikī ka bandwidth o kēia mau mea hana e hoʻokō i ke koi. Pili kēia palena i nā waiwai kūlohelohe o ka silicon - ʻo ke kaulike o ka pale ʻana i ka nalowale nui o ka mālamalama ʻoiai e mālama ana i ka conductivity lawa e hana i nā tradeoffs hiki ʻole ke pale ʻia.
ʻO ka ʻenehana modulator a me nā mea hana e kū mai ana
Ua hoʻokele nā palena o nā modulators silicon-based kuʻuna i ka noiʻi ʻana i nā mea ʻē aʻe a me nā ʻenehana hoʻohui. Ua lilo ka lithium niobate ʻili lahilahi i hoʻokahi o nā kahua hoʻohiki nui loa no kahi hanauna hou o nā modulators.Nā modulators electro-optic lithium niobate ʻili lahilahihoʻoilina i nā ʻano maikaʻi loa o ka lithium niobate nui, me: ka puka aniani ākea, ka coefficient electro-optic nui (r33 = 31 pm/V) cell linear Hiki i ka hopena Kerrs ke hana i nā pae nalu he nui
Ua loaʻa i nā holomua hou i ka ʻenehana lithium niobate lahilahi nā hopena kupaianaha, me kahi modulator e hana ana ma 260 Gbaud me nā helu ʻikepili o 1.96 Tb/s no kēlā me kēia kahawai. Loaʻa i ka paepae nā pono kūikawā e like me ka volta hoʻokele CMOS-compatible a me ka bandwidth 3-dB o 100 GHz.
Ka hoʻohana ʻenehana hou
ʻO ka hoʻomohala ʻana o nā modulators electro optic e pili pono ana i nā noi e kū mai ana ma nā ʻano he nui. Ma ke kahua o ka naʻauao hana a me nā kikowaena ʻikepili,nā modulators wikiwikihe mea nui ia no ka hanauna hou o nā pilina, a ke hoʻokele nei nā noi helu AI i ke koi no nā transceivers pluggable 800G a me 1.6T. Hoʻopili ʻia ka ʻenehana modulator i: ka hana ʻike quantum neuromorphic computing Frequency modulated continuous wave (FMCW) lidar microwave photon technology
ʻO ke ʻano kūikawā, hōʻike nā modulators electro-optic lithium niobate lahilahi i ka ikaika i nā ʻenekini hana computational optical, e hāʻawi ana i ka modulation mana haʻahaʻa wikiwiki e hoʻolalelale i ke aʻo ʻana o ka mīkini a me nā noi akamai artificial. Hiki i kēlā mau modulators ke hana i nā mahana haʻahaʻa a kūpono no nā interfaces quantum-classical i nā laina superconducting.
ʻO ka hoʻomohala ʻana o nā modulators electro optic hanauna hou e kū nei i kekahi mau pilikia nui: Ke kumukūʻai hana a me ka unahi: ua kaupalena ʻia nā modulators lithium niobate lahilahi i ka hana wafer 150 mm i kēia manawa, e hopena ana i nā kumukūʻai kiʻekiʻe. Pono ka ʻoihana e hoʻonui i ka nui o ka wafer me ka mālama ʻana i ka like a me ka maikaʻi o ke kiʻiʻoniʻoni. Hoʻohui a me ka hoʻolālā like: ʻO ka hoʻomohala holomua onā modulators hana kiʻekiʻepono nā mākaukau hoʻolālā like piha, e pili ana i ka laulima ʻana o nā mea hoʻolālā optoelectronics a me nā mea hoʻolālā chip uila, nā mea hoʻolako EDA, nā kumu, a me nā loea hoʻopili. Paʻakikī hana: ʻOiai ʻoi aku ka paʻakikī o nā kaʻina hana optoelectronics e pili ana i ka silicon ma mua o nā electronics CMOS holomua, ʻo ka hoʻokō ʻana i ka hana paʻa a me ka hua e pono ai ka ʻike loea nui a me ka hoʻonui ʻana i ke kaʻina hana.
Hoʻokele ʻia e ka ulu ʻana o ka AI a me nā kumu geopolitical, ke loaʻa nei i ke kahua ka hoʻonui ʻana i ka hoʻopukapuka kālā mai nā aupuni, nā ʻoihana a me ka ʻāpana pilikino a puni ka honua, e hana ana i nā manawa hou no ka laulima ʻana ma waena o ka academia a me ka ʻoihana a me ka hoʻohiki e hoʻolalelale i ka hana hou.
