Rare ntiaj teb optical fiber ntau: "tshwj xeeb kho qhov muag fiber ntau" uas illuminates cov ntaub ntawv hnub nyoog, lub teb chaws cov khoom muaj nqis los ntawm kev sib txuas lus mus rau siab -lub zog lasers.
Nyob rau hauv lub ntiaj teb no ntawm optical fiber technology, muaj ib tug tshwj xeeb hom ntawm fiber uas "glows", uas tsis tsuas yog ua hauj lwm raws li lub hauv paus ntawm cov ntaub ntawv superhighway tab sis kuj ua raws li lub zog tsav tsheb tom qab lub laser tshuab kiv puag ncig. Qhov no yog lub ntiaj teb tsis tshua muaj fiber ntau - los ntawm "doping" ib kab ntawm cov ntsiab lus tsis tshua muaj hauv ntiaj teb rau hauv cov iav kho qhov muag, nws muab cov fibers zoo tib yam nrog lub peev xwm txawv tshaj plaw ntawm "lub teeb amplification" thiab "laser output".
Qhov tsis meej ntawm lub ntiaj teb tsis tshua muaj fibers nyob rau hauv lub zog tshwj xeeb theem qauv ntawm lanthanide ntsiab. Thaum cov wavelengths tshwj xeeb ntawm lub teeb pom kev zoo ua rau lub ntiaj teb tsis tshua muaj ions (xws li erbium, ytterbium, thiab thulium) hauv fiber ntau, cov ions no tuaj yeem nqus tau lub zog thiab hloov mus rau siab - lub zog. Tom qab ntawd, nyob rau hauv kev cuam tshuam ntawm teeb liab teeb, lawv tso tawm photons ntawm tib zaus thiab theem los ntawm kev txhawb nqa emission, yog li ua tiav zoo meej amplification ntawm lub teeb liab los yog txawm ncaj qha generating siab - zoo lasers. Ntawm lawv, erbium-doped fiber ntau (EDF) yog qhov tsis zoo tshaj plaws tom qab kev sib txuas lus kho qhov muag thoob ntiaj teb, nrog rau nws lub qhov rais amplification zoo kawg nkaus txuam qhov poob qis tshaj ntawm cov fiber ntau; ytterbium-doped fiber ntau (YDF) yog "lub plawv" ntawm kev lag luam siab - fais fab fiber lasers, muab kev ntseeg tau lub zog tso zis ntawm kilowatts lossis txawm kaum ntawm kilowatts; thulium-doped fiber ntau (TDF) tau qhib 2-micron wavelength band laser uas muaj kev nyab xeeb rau tib neeg lub qhov muag, thiab muaj txiaj ntsig tshwj xeeb hauv kev kho mob thiab kev paub.
Yog tias cov khoom siv kho qhov muag zoo tib yam yog "txoj kev loj" rau cov ntaub ntawv kis tau tus mob, ces lub ntiaj teb tsis tshua muaj qhov kho qhov muag fibers yog qhov tseem ceeb ntawm "cov chaw nres tsheb hluav taws xob" thiab "lub zog hluav taws xob" raws txoj kev.
· Lub hauv paus ntawm kev sib txuas lus kho qhov muag: Lub EDFA (Erbium-Doped Fiber Amplifier) nyob rau ntawm erbium-doped fibers yog lub ntsiab lus tseem ceeb tsav tsheb ntev - nrug thiab siab - muaj peev xwm wavelength division multiplexing systems. Los ntawm transoceanic submarine cables mus rau lub teb chaws lub cev kab, nws ua haujlwm ntsiag to txhua qhov chaw.
· Cov cuab yeej muaj zog rau kev tsim khoom siab heev: Lub siab- lub zog fiber ntau laser raws li ytterbium-doped fibers, nrog nws cov nqaj zoo, kev ua tau zoo thiab kev ntseeg tau, tau dhau los ua "super tool" rau kev txiav thiab vuam hauv cov teb xws li tsheb, nkoj, aerospace thiab lwm yam.
· Nyob rau hauv pem hauv ntej ntawm technology: Tsis tshua muaj lub ntiaj teb fibers yog qhov tseem ceeb nce nruab nrab rau tom ntej - tiam quantum kev sib txuas lus, laser radar, qhov chaw optical kev sib txuas lus thiab lwm yam systems. Lawv qhov kev ua tau zoo ncaj qha txiav txim siab theem ntawm kev ua tiav hauv kev txiav - thev naus laus zis.
Tuam Tshoj tsis tsuas yog muaj lub ntiaj teb zoo tshaj cov khoom siv pob zeb hauv ntiaj teb, tab sis kuj tau ua tiav kev ua tiav hauv kev tshawb fawb thiab kev lag luam ntawm lub ntiaj teb tsis tshua muaj fiber ntau. Cov tsev tshawb fawb hauv tsev thiab cov tuam txhab lag luam tau kov yeej cov kev lag luam ua tiav los ntawm kev npaj siab -purity tsawg lub ntiaj teb raw cov ntaub ntawv, tsim tshwj xeeb optical fiber preforms, rau cov txheej txheem ntawm kev kos duab, thiab tau paub txog kev ywj pheej ntawm cov khoom tseem ceeb. Raws li kev taw qhia ntawm lub teb chaws cov tswv yim xws li "Ua nyob rau hauv Tuam Tshoj 2025", domestic tsawg lub ntiaj teb optical fibers tau mus txog lub ntiaj teb no qib siab nyob rau hauv cov ntsiab lus tseem ceeb xws li tso zis hwj chim, conversion efficiency, thiab ntev - lub sij hawm cia siab rau, thiab txuas ntxiv mus ua breakthroughs mus rau siab dua kev ua tau zoo thiab ntau tshwj xeeb nta (xws li hluav taws xob tsis kam, siab -) cov ntaub ntawv kub. kom ntseeg tau tias lub teb chaws cov ntaub ntawv thiab kev ruaj ntseg ntawm lub zog thiab tuav lub commanding heights ntawm siab -end manufacturing.
Nyob rau hauv lub neej yav tom ntej, nws yuav tsis tsuas yog ib tug -function ntaus ntawv, tab sis kuj yuav sib sib zog nqus ua ke nrog silicon photonic chips thiab cov ntaub ntawv tshiab, dhau los ua "core optical material" rau tsim tag nrho - optical networks, quantum information networks thiab tom ntej - tiam siab - zog physics chaw. Lub teeb ntawm lub teeb emissions los ntawm microscopic tsawg lub ntiaj teb ions yog illuminating lub dav yav tom ntej xws li kev tshawb fawb los ntawm lub teb chaws engineering.
