O le au suʻesuʻe a Prof. Khonina mai le Institute of Image Processing Systems o le Russian Academy of Sciences na lomia se pepa e faʻaulutalaina "Optical multiplexing techniques and their marriage" i leOpto-ElectronicFa'asilasilaga mo luga ole masini mafeso'ota'iga fiber opitika: o se toe iloiloga.O le vaega su'esu'e a Polofesa Khonina ua fa'atupuina le tele o elemene opitika eseese mo le fa'atinoina o le MDM i avanoa avanoa mafiber optics.Ae o le bandwidth network e pei o le "lava la'ei", e le tele tele, e le lava.O tafega o faʻamatalaga ua faʻatupuina ai se manaʻoga paʻu mo fefaʻatauaiga.O fe'au imeli pupuu o lo'o suitulaga i ata fa'aola e ave ai le bandwidth.Mo faʻamatalaga, vitio ma leo faʻasalalauga fesoʻotaʻiga na o ni nai tausaga talu ai na tele le bandwidth, o loʻo vaʻavaʻai nei pulega o fesoʻotaʻiga e faia se auala e le masani ai e faʻafetaui ai le manaʻoga e le gata mo le bandwidth.E tusa ai ma lona poto masani i lenei vaega o suʻesuʻega, na aoteleina ai e Polofesa Khonina le alualu i luma sili ona lata mai ma sili ona taua i le tulaga o le multiplexing i le mea sili na te mafaia.O autu o loʻo aofia i le iloiloga e aofia ai le WDM, PDM, SDM, MDM, OAMM, ma le tolu faʻaogaina tekonolosi o WDM-PDM, WDM-MDM, ma PDM-MDM.Faatasi ai ma i latou, naʻo le faʻaaogaina o se hybrid WDM-MDM multiplexer, N × M auala e mafai ona iloa e ala i N wavelengths ma M guide modes.
O le Inisetiute o Faiga Faʻatonu Faʻatonu a le Rusia Academy of Sciences (IPSI RAS, lea o se lala o le Federal Scientific Research Center o le Russian Academy of Sciences "Crystallography and Photonics") na faavaeina i le 1988 i luga o le faavae o se vaega suʻesuʻe i Samara. Iunivesite a le Setete.O le au o loʻo taʻitaʻia e Victor Alexandrovich Soifer, o se sui o le Russian Academy of Sciences.O se tasi o faʻatonuga suʻesuʻe a le vaega suʻesuʻe o le atinaʻeina o metotia numera ma suʻesuʻega faʻataʻitaʻiga o faʻalava laser tele-channel.O nei suʻesuʻega na amata i le 1982, ina ua faʻataunuʻuina muamua le tele-channel diffracted optical element (DOE) i le galulue faʻatasi ma le au a le Nobel Laureate i le fisiki, Academician Alexander Mikhailovich Prokhorov.I tausaga na soso'o ai, na fa'atūina e saienitisi IPSI RAS, fa'ata'ita'i ma su'esu'eina le tele o ituaiga o elemene DOE i luga o komepiuta, ona fa'atupuina lea i foliga o holograms vaega fa'apipi'i fa'atasi ma fa'asologa o le laser transverse.O fa'ata'ita'iga e aofia ai vortices opitika, Lacroerre-Gauss mode, Hermi-Gauss mode, Bessel mode, Zernick function (mo su'esu'ega aberration), ma isi. O lenei DOE, faia i le fa'aogaina o le electron lithography, e fa'aoga i su'esu'ega fa'amau e fa'avae i luga o le fa'avasegaina o le fa'aogaina.O fua o fua e maua i le tulaga o faʻasalalauga pito i luga i nisi vaega (faʻatonuga faʻasologa) i le Fourier vaalele o lefaiga opitika.Mulimuli ane, na faʻaaogaina le taʻiala e gaosia ai laʻau lavelave, faʻapea foʻi ma faʻamaʻi faʻapipiʻi i filo opitika, avanoa avanoa, ma faʻasalalauga faʻalavelave e faʻaaoga ai le DOE ma le faʻafanua.Optical modulators.
