Iqela lophando likaProf. Khonina ovela kwiZiko leeNkqubo zokuLungisa iMifanekiso ye-Russian Academy of Sciences lipapashe iphepha elinesihloko esithi “Iindlela zokuphindaphinda ii-Optical multiplexing kunye nomtshato wabo”I-Opto-ElectronicUkuqhubela phambili kwi-chip kunyeunxibelelwano lwefiber optical: uphononongo.Iqela lophando likaNjingalwazi Khonina liye laphuhlisa izinto ezininzi ze-optical diffractive zokuphumeza i-MDM kwindawo yamahhala kunyeifayibha optics.Kodwa i-bandwidth yenethiwekhi ifana "ne-wardrobe ye-wardrobe", ayikaze ibe nkulu kakhulu, ayizange yanele.Ukuhamba kwedatha kudale imfuno eqhumayo yetrafikhi.Imiyalezo emifutshane ye-imeyile ithathelwa indawo yimifanekiso eshukumayo ethatha i-bandwidth.Kwidatha, ividiyo kunye nothungelwano losasazo lwelizwi kwiminyaka embalwa edlulileyo kuphela yayine-bandwidth eninzi, abasemagunyeni bonxibelelwano ngoku bajonge ukuthatha indlela engaqhelekanga yokuhlangabezana nemfuno engapheliyo ye-bandwidth.Ngokusekelwe kumava akhe abanzi kule ndawo yophando, uNjingalwazi uKhonina ushwankathele intuthuko yamva nje kunye neyona nto ibalulekileyo kwinkalo yokuphindaphinda ngokusemandleni akhe.Izihloko ezigutyungelwe kuhlaziyo ziquka i-WDM, iPDM, iSDM, i-MDM, i-OAMM, kunye neeteknoloji ezintathu ezixubileyo ze-WDM-PDM, i-WDM-MDM, kunye ne-PDM-MDM.Phakathi kwabo, kuphela ngokusebenzisa i-multiplexer ye-WDM-MDM exubileyo, iziteshi ze-N × M ziyakwazi ukufezekiswa nge-N wavelengths kunye neendlela zesikhokelo ze-M.
Iziko leeNkqubo zokuLungiswa koMfanekiso weRussian Academy of Sciences (IPSI RAS, ngoku isebe le-Federal Scientific Research Centre ye-Russian Academy of Sciences "Crystallography and Photonics") yasekwa ngo-1988 ngesiseko seqela lophando eSamara. IYunivesithi yaseState.Iqela likhokelwa nguVictor Alexandrovich Soifer, ilungu leRussia Academy of Sciences.Enye yezalathiso zophando zeqela lophando kuphuhliso lweendlela zamanani kunye nezifundo zovavanyo lwemiqadi yelaser eneendlela ezininzi.Ezi zifundo zaqala ngo-1982, xa i-multi-channel diffracted optical element yokuqala (DOE) yaqatshelwa ngokubambisana neqela leNobel Laureate kwi-physics, i-Academician Alexander Mikhailovich Prokhorov.Kwiminyaka eyalandelayo, izazinzulu ze-IPSI RAS zandulula, zalinganisa kwaye zafunda iindidi ezininzi zezinto ze-DOE kwiikhompyuter, zaza emva koko zazenza ngohlobo lweehologram zesigaba esibekwe ngaphezulu esinemigangatho yelaser engaguqukiyo.Imizekelo ibandakanya i-vortices optical, i-Lacroerre-Gauss mode, i-Hermi-Gauss mode, imodi ye-Bessel, umsebenzi we-Zernick (ukuhlaziywa kwe-aberration), njl.Iziphumo zomlinganiselo zifumaneka ngohlobo lweencopho zolungelelaniso kwiindawo ezithile (i-diffraction orders) kwinqwelomoya yeFourierinkqubo yamehlo.Emva koko, umgaqo wasetyenziselwa ukuvelisa imiqadi entsonkothileyo, kunye nokudityaniswa kwemiqadi kwimicu ye-optical fibers, indawo ekhululekileyo, kunye nemithombo yeendaba enesiphithiphithi kusetyenziswa i-DOE kunye nendawo.Iimodyuli zamehlo.
