Njira za Optical multiplexing ndi ukwati wawo pa-chip ndi kuwala kwa fiber kulankhulana

Gulu lofufuza la Prof. Khonina wochokera ku Institute of Image Processing Systems of the Russian Academy of Sciences linasindikiza pepala lotchedwa “Optical multiplexing techniques and their marriage”Opto-ElectronicZotsogola za pa-chip ndikuyankhulana kwa fiber: ndemanga.Gulu lofufuza la Professor Khonina lapanga zinthu zingapo zowoneka bwino zogwiritsa ntchito MDM pamalo aulere komansofiber Optics.Koma bandwidth yamtaneti ili ngati "zovala zanu", osati zazikulu, zosakwanira.Mayendedwe a data apangitsa kuti anthu azichulukirachulukira.Mauthenga amfupi a imelo akusinthidwa ndi zithunzi zamakanema zomwe zimatenga bandwidth.Kwa ma data, makanema ndi makanema owulutsa mawu omwe zaka zingapo zapitazo anali ndi bandwidth yambiri, olamulira patelefoni tsopano akuyang'ana kuti atenge njira yosagwirizana kuti akwaniritse kufunikira kosatha kwa bandwidth.Potengera zomwe adakumana nazo m'derali la kafukufukuyu, Pulofesa Khonina anafotokoza mwachidule za kupita patsogolo kwaposachedwa komanso zofunika kwambiri pankhani yochulukitsa kuchuluka komwe akanatha.Mitu yomwe yafotokozedwa pakuwunikaku ikuphatikiza WDM, PDM, SDM, MDM, OAMM, ndi matekinoloje atatu osakanizidwa a WDM-PDM, WDM-MDM, ndi PDM-MDM.Mwa iwo, pogwiritsa ntchito hybrid WDM-MDM multiplexer, njira za N×M zitha kuzindikirika kudzera munjira za N wavelengths ndi M zowongolera.

Institute of Image Processing Systems ya Russian Academy of Sciences (IPSI RAS, yomwe tsopano ndi nthambi ya Federal Scientific Research Center ya Russian Academy of Sciences "Crystallography ndi Photonics") inakhazikitsidwa mu 1988 pamaziko a gulu lofufuza ku Samara. State University.Gululi likutsogoleredwa ndi Victor Alexandrovich Soifer, membala wa Russian Academy of Sciences.Mmodzi mwa mayendedwe ofufuza a gulu lofufuza ndikukhazikitsa njira zamawerengero ndi maphunziro oyesera a matabwa a ma laser anjira zambiri.Maphunzirowa anayamba mu 1982, pamene woyamba Mipikisano njira diffracted kuwala chinthu (DOE) anazindikira mogwirizana ndi gulu la Nobel Laureate mu sayansi, Academician Alexander Mikhailovich Prokhorov.M’zaka zotsatira, asayansi a IPSI RAS anakonza, kuyerekezera ndi kuphunzira mitundu yambiri ya zinthu za DOE pamakompyuta, kenako n’kuzipanga m’njira ya mahologalamu ophatikizika kwambiri okhala ndi ma laser osinthasintha.Zitsanzo zikuphatikizapo ma vortices optical, Lacroerre-Gauss mode, Hermi-Gauss mode, Bessel mode, Zernick ntchito (kwa aberration analysis), etc. DOE iyi, yopangidwa pogwiritsa ntchito electron lithography, imagwiritsidwa ntchito pakuwunika kwazitsulo pogwiritsa ntchito kuwonongeka kwa mawonekedwe a kuwala.Zotsatira zoyezera zimapezeka ngati nsonga zamalumikizidwe pazigawo zina (madongosolo a diffraction) mu ndege ya Fourier yaOptical system.Pambuyo pake, mfundoyi idagwiritsidwa ntchito popanga matabwa ovuta, komanso mizati yowonongeka mu ulusi wa kuwala, malo omasuka, ndi zofalitsa zosokoneza pogwiritsa ntchito DOE ndi malo.Optical modulators.
