Kev siv tshuab sib txuas lus ntawm cov ntaub ntawv silicon photonic

Silicon photonicskev siv tshuab sib txuas lus ntaub ntawv
Hauv ntau pawg ntawmcov khoom siv photonic, cov khoom siv silicon photonic sib tw nrog cov khoom siv zoo tshaj plaws, uas tau tham hauv qab no. Tej zaum qhov peb xav tias yog txoj haujlwm hloov pauv tshaj plaws hauvkev sib txuas lus kho qhov muagyog kev tsim cov platforms sib koom ua ke uas sib koom ua ke modulators, detectors, waveguides, thiab lwm yam khoom ntawm tib lub chip uas sib txuas lus nrog ib leeg. Qee zaum, transistors kuj suav nrog hauv cov platforms no, tso cai rau lub amplifier, serialization, thiab feedback kom txhua tus sib koom ua ke ntawm tib lub chip. Vim yog tus nqi ntawm kev tsim cov txheej txheem zoo li no, qhov kev siv zog no yog tsom rau cov ntawv thov rau kev sib txuas lus cov ntaub ntawv peer-to-peer. Thiab vim yog tus nqi ntawm kev tsim cov txheej txheem tsim transistor, qhov kev pom zoo tshiab hauv daim teb yog tias, los ntawm kev ua tau zoo thiab tus nqi, nws ua rau muaj kev nkag siab zoo tshaj plaws rau yav tom ntej los sib koom ua ke cov khoom siv hluav taws xob los ntawm kev ua cov thev naus laus zis ntawm wafer lossis chip theem.

Muaj qhov tseem ceeb pom tseeb hauv kev ua cov chips uas tuaj yeem suav siv cov khoom siv hluav taws xob thiab nqa tawm kev sib txuas lus optical. Feem ntau ntawm cov ntawv thov thaum ntxov ntawm silicon photonics yog nyob rau hauv kev sib txuas lus cov ntaub ntawv digital. Qhov no yog tsav los ntawm qhov sib txawv ntawm lub cev ntawm electrons (fermions) thiab photons (bosons). Electrons zoo heev rau kev suav vim tias ob qho ntawm lawv tsis tuaj yeem nyob rau tib qho chaw tib lub sijhawm. Qhov no txhais tau tias lawv sib cuam tshuam zoo nrog ib leeg. Yog li ntawd, nws muaj peev xwm siv electrons los tsim cov khoom siv hloov pauv nonlinear loj - transistors.

Cov photons muaj cov khoom sib txawv: ntau cov photons tuaj yeem nyob rau tib qho chaw tib lub sijhawm, thiab nyob rau hauv cov xwm txheej tshwj xeeb heev lawv tsis cuam tshuam nrog ib leeg. Yog vim li cas nws thiaj li ua tau kom xa cov trillions ntawm cov ntaub ntawv ib ob los ntawm ib qho fiber: nws tsis yog ua los ntawm kev tsim cov ntaub ntawv ntws nrog ib qho terabit bandwidth.

Hauv ntau qhov chaw ntawm lub ntiaj teb, fiber mus rau hauv tsev yog qhov tseem ceeb nkag mus rau paradigm, txawm hais tias qhov no tsis tau ua pov thawj tias muaj tseeb hauv Tebchaws Meskas, qhov chaw nws sib tw nrog DSL thiab lwm yam thev naus laus zis. Nrog rau qhov kev thov tas li rau bandwidth, qhov xav tau los tsav tsheb ntau dua thiab ua haujlwm tau zoo dua ntawm kev xa cov ntaub ntawv los ntawm fiber optics kuj tseem loj hlob zuj zus. Qhov sib txawv dav hauv kev lag luam sib txuas lus cov ntaub ntawv yog tias thaum qhov deb txo qis, tus nqi ntawm txhua ntu txo qis thaum lub ntim nce ntxiv. Tsis yog qhov xav tsis thoob, kev siv zog ua lag luam silicon photonics tau tsom mus rau ntau yam haujlwm ntawm cov ntawv thov ntim siab, luv luv, tsom mus rau cov chaw khaws ntaub ntawv thiab kev suav ua haujlwm siab. Cov ntawv thov yav tom ntej yuav suav nrog board-to-board, USB-scale luv luv-kev sib txuas, thiab tej zaum txawm tias CPU core-to-core kev sib txuas lus thaum kawg, txawm hais tias qhov yuav tshwm sim nrog core-to-core daim ntawv thov ntawm lub nti tseem yog qhov kwv yees xwb. Txawm hais tias nws tseem tsis tau mus txog qhov ntsuas ntawm CMOS kev lag luam, silicon photonics tau pib ua ib qho kev lag luam tseem ceeb.
