Ib hom amplifier optical uas siv ntau hauv kev sib txuas lus optical

Ib hom uas siv ntaulub tshuab ua kom pom kev zoosiv rau hauv kev sib txuas lus kho qhov muag

Thaum cov teeb liab optical raug xa mus rau hauv cov fibers optical, thaum qhov deb nce ntxiv, cov teeb liab optical yuav maj mam qaug zog thiab ua rau muaj kev cuam tshuam kev sib txuas lus ... Txog thaum cov amplifiers optical tshwm sim, lawv zoo li "chaw nres tsheb roj", rov ua kom lub zog ntawm cov teeb liab optical kom lawv tuaj yeem nqa cov ntaub ntawv mus rau qhov chaw mus tau zoo. Qhov teeb meem no yuav qhia rau koj txog lub amplifier optical hauv kev sib txuas lus optical - luberbium-doped fiber amplifier(EDFA kho qhov muag amplifier).

Ib lub erbium-doped fiber amplifier, raws li lub npe qhia: Erbium (Er), ib qho khoom tsis tshua muaj av, tau koom ua ke rau hauv quartz fiber. Thaum lub teeb liab nkag mus dhau los ntawm erbium-doped fiber, cov trivalent erbium ions (Er³⁺) yuav nqus lub zog ntawm lub teeb twj tso kua mis thiab hloov mus rau qib zog siab dua. Tus naj npawb ntawm cov khoom me me hauv lub xeev zoo siab dhau los ua inversion. Nyob rau hauv qhov kev cuam tshuam ntawm lub teeb liab nkag, cov ion tsis tshua muaj av zoo siab dhau los ua kev tso tawm thiab tso tawm cov photons ntawm tib zaus li lub teeb liab, yog li ua tiav kev ua kom pom kev zoo.
Cov khoom uas ua rau ib qhoEDFA kho qhov muag amplifierFeem ntau suav nrog cov khoom siv sib txuas lus optical (feem ntau siv cov wavelength division multiplexers WDM), cov khoom siv cais tawm optical, cov fibers erbium-doped, cov lim dej, thiab cov twj tso kua mis. Ntawm lawv, cov khoom siv sib txuas lus optical sib xyaw ua ke lub teeb nkag thiab lub teeb twj tso kua mis kom ntseeg tau tias lub teeb liab raug txhaj rau hauv cov fiber erbium-doped; lub luag haujlwm ntawm cov khoom siv cais tawm optical yog los tswj cov teeb pom kev tsis muaj txiaj ntsig hauv txoj kev kho qhov muag kom tiv thaiv cov teeb liab cuam tshuam tsis tsim nyog los ntawm kev tsim, xyuas kom meej tias kev xa mus rau ib qho kev taw qhia ntawm lub teeb liab; lub lim dej optical tshem tawm cov suab nrov tsis xav tau los txhim kho qhov sib piv ntawm lub teeb liab thiab suab nrov thiab xyuas kom meej qhov tseeb ntawm kev xa cov ntaub ntawv.
Tam sim no, cov kws tshawb fawb tab tom tsim cov amplifiers fiber ntau ob txoj kab (DBFA) thiab ultra-wideband amplifiers (UWOA), lub hom phiaj yog txuas ntxiv qhov nce bandwidth mus rau tag nrho cov wavelength division multiplexing (WDM) frequency band. Tsis ntev los no, ib pab pawg tshawb fawb sib koom ua ke los ntawm cov koom haum tshawb fawb European tau tsim ib lub amplifier parametric wave parametric raws li cov chips photonic. Los ntawm ib qho qauv compact, nws ua tiav ultra-wideband signal amplification, nrog bandwidth ntawm 140 nm (peb zaug ntawm EDFA ib txwm muaj), thiab qhov ntim tau raug txo kom txog qib centimeter, muab kev txhawb nqa ultra-high-speed rau cov chaw khaws ntaub ntawv thiab AI computing. Cov "super amplifiers" no yuav txhawb nqa kev xa ntau dua ib puas wavelengths ib fiber, tso lub hauv paus rau kev sib txuas lus holographic thiab cov chaw tsim khoom ntse thiab lwm yam kev siv hauv 6G era.
