Pab neeg tshawb fawb ntawm Prof. Khonina los ntawm lub koom haum ntawm Image Processing Systems ntawm Lavxias teb sab Academy ntawm Sciences luam tawm ib daim ntawv hu ua "Optical multiplexing techniques thiab lawv kev sib yuav" nyob rau hauvOpto-ElectronicUa ntej rau on-chip thiaboptical fiber kev sib txuas lus: kev tshuaj xyuas.Xibfwb Khonina cov kev tshawb fawb pab pawg tau tsim ntau yam diffractive optical ntsiab rau kev siv MDM hauv qhov chaw dawb thiabfiber ntau optics.Tab sis network bandwidth zoo li "tus kheej wardrobe", yeej tsis loj heev, yeej tsis txaus.Cov ntaub ntawv ntws tau tsim muaj kev xav tau ntau heev rau kev khiav tsheb.Cov lus luv luv email tau raug hloov los ntawm cov duab animated uas siv bandwidth.Rau cov ntaub ntawv, yees duab thiab lub suab tshaj tawm hauv xov tooj cua uas tsuas yog ob peb xyoos dhau los muaj ntau ntawm bandwidth, cov tub ceev xwm hauv xov tooj tam sim no tab tom nrhiav los ua txoj hauv kev tsis zoo los ua kom tau raws li qhov kev thov tsis kawg rau bandwidth.Raws li nws qhov kev paub dhau los hauv cheeb tsam ntawm kev tshawb fawb no, xibfwb Khonina tau sau tseg qhov kev nce qib tshiab thiab tseem ceeb tshaj plaws hauv kev ua haujlwm ntawm multiplexing raws li qhov nws ua tau.Cov ncauj lus uas tau hais hauv qhov kev tshuaj xyuas suav nrog WDM, PDM, SDM, MDM, OAMM, thiab peb qhov kev siv thev naus laus zis ntawm WDM-PDM, WDM-MDM, thiab PDM-MDM.Ntawm lawv, tsuas yog los ntawm kev siv hybrid WDM-MDM multiplexer, N × M raws tuaj yeem paub los ntawm N wavelengths thiab M qhia hom.
Lub koom haum ntawm Cov Duab Txheej Txheem ntawm Lavxias Academy ntawm Kev Tshawb Fawb (IPSI RAS, tam sim no yog ib ceg ntawm Tsoom Fwv Teb Chaws Tshawb Fawb Kev Tshawb Fawb ntawm Lavxias Academy ntawm Kev Tshawb Fawb "Crystallography thiab Photonics") tau tsim nyob rau xyoo 1988 los ntawm pawg tshawb fawb ntawm Samara. State University.Pab neeg no yog coj los ntawm Victor Alexandrovich Soifer, ib tug tswv cuab ntawm Lavxias teb sab Academy ntawm Sciences.Ib qho ntawm cov lus qhia kev tshawb fawb ntawm pab pawg tshawb fawb yog kev txhim kho cov lej ntawm cov txheej txheem thiab kev sim kev tshawb fawb ntawm ntau cov kab hluav taws xob laser.Cov kev tshawb fawb no tau pib nyob rau xyoo 1982, thaum thawj qhov sib txawv ntawm ntau qhov sib txawv ntawm qhov muag pom (DOE) tau paub txog kev koom tes nrog pab pawg ntawm Nobel Laureate hauv physics, Academician Alexander Mikhailovich Prokhorov.Nyob rau hauv lub xyoo tom qab, IPSI RAS cov kws tshawb fawb tau npaj, simulated thiab kawm ntau hom DOE cov ntsiab lus ntawm cov khoos phis tawj, thiab tom qab ntawd tsim lawv los ntawm ntau yam superimposed theem holograms nrog cov qauv transverse laser.Piv txwv xws li optical vortices, Lacroerre-Gauss hom, Hermi-Gauss hom, Bessel hom, Zernick muaj nuj nqi (rau aberration tsom xam), thiab lwm yam. Qhov no DOE, ua siv electron lithography, yog siv rau beam tsom xam raws li optical hom decomposition.Cov txiaj ntsig kev ntsuas tau txais nyob rau hauv daim ntawv ntawm correlation peaks ntawm qee cov ntsiab lus (diffraction xaj) hauv Fourier dav hlau ntawmkho qhov muag system.Tom qab ntawd, lub hauv paus ntsiab lus tau siv los tsim cov kab teeb meem nyuaj, nrog rau demultiplexing beams hauv optical fibers, qhov chaw dawb, thiab cov xov xwm turbulent siv DOE thiab spatial.Optical modulators.
