Silicon photonic cov ntaub ntawv kev sib txuas lus technology

Silicon photoniccov ntaub ntawv kev sib txuas lus technology
Nyob rau hauv ob peb pawg ntawmcov khoom siv photonic, silicon photonic Cheebtsam yog kev sib tw nrog cov khoom siv zoo tshaj plaws hauv chav kawm, uas tau tham hauv qab no. Tej zaum qhov peb xav tias yog qhov kev hloov pauv tshaj plaws hauv kev ua haujlwmkev sib txuas lus kho qhov muagyog tsim los ntawm kev sib koom ua ke platforms uas integrates modulators, detectors, waveguides, thiab lwm yam Cheebtsam ntawm tib nti uas sib txuas lus nrog ib leeg. Qee zaum, transistors kuj suav nrog hauv cov platforms no, tso cai rau lub suab nrov, serialization, thiab tawm tswv yim rau txhua tus ua ke ntawm tib lub nti. Vim tus nqi ntawm kev tsim cov txheej txheem zoo li no, qhov kev siv zog no feem ntau yog tsom rau cov ntawv thov rau kev sib txuas lus cov ntaub ntawv rau cov phooj ywg. Thiab vim yog tus nqi ntawm kev tsim cov txheej txheem transistor, qhov kev pom zoo tshwm sim hauv thaj chaw yog tias, los ntawm kev ua tau zoo thiab tus nqi pom, nws ua rau muaj kev nkag siab zoo tshaj plaws rau yav tom ntej rau kev sib koom ua ke ntawm cov khoom siv hluav taws xob los ntawm kev ua cov cuab yeej sib txuas ntawm wafer lossis nti. qib.

Nws muaj txiaj ntsig zoo hauv kev tuaj yeem ua cov chips uas tuaj yeem suav nrog cov khoom siv hluav taws xob thiab ua cov kev sib txuas lus kho qhov muag. Feem ntau ntawm cov ntawv thov thaum ntxov ntawm silicon photonics yog nyob rau hauv cov ntaub ntawv sib txuas lus. Qhov no yog tsav los ntawm lub cev qhov sib txawv ntawm electrons (fermions) thiab photons (bosons). Electrons yog qhov zoo rau kev suav vim tias ob qho ntawm lawv tsis tuaj yeem nyob hauv ib qho chaw tib lub sijhawm. Qhov no txhais tau hais tias lawv muaj kev sib raug zoo nrog ib leeg. Yog li ntawd, nws muaj peev xwm siv electrons los tsim loj-scale nonlinear hloov khoom siv - transistors.

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

Hauv ntau qhov chaw ntawm lub ntiaj teb, fiber ntau rau hauv tsev yog qhov tseem ceeb ntawm kev nkag mus rau lub ntsiab lus, 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 tsis tu ncua rau bandwidth, qhov yuav tsum tau tsav ntau thiab ntau dua kev sib kis ntawm cov ntaub ntawv los ntawm fiber ntau optics tseem loj hlob tsis tu ncua. Txoj kev dav dav hauv cov ntaub ntawv kev sib txuas lus kev lag luam yog tias qhov kev ncua deb zuj zus, tus nqi ntawm txhua ntu txo qis thaum lub ntim nce. Tsis yog qhov xav tsis thoob, silicon photonics kev lag luam kev lag luam tau tsom mus rau qhov tseem ceeb ntawm kev ua haujlwm ntawm cov ntawv ntim siab, luv luv, tsom rau cov chaw zov me nyuam cov ntaub ntawv thiab kev ua haujlwm siab. Cov ntawv thov yav tom ntej yuav suav nrog board-to-board, USB-scale kev sib txuas luv luv, thiab tej zaum txawm tias CPU core-rau-core kev sib txuas lus thaum kawg, txawm tias yuav muaj dab tsi tshwm sim nrog cov ntawv thov tseem ceeb ntawm cov nti tseem yog qhov xav tau zoo. Txawm hais tias nws tseem tsis tau mus txog qhov ntsuas ntawm CMOS kev lag luam, silicon photonics tau pib los ua kev lag luam tseem ceeb.
