Amasu wokukhanya okuningana nemishado yawo yokuxhumana kwe-on-chip kanye ne-fiber

Iqembu lokucwaninga lakwaProf Khonina lisuka kwiSikhungo Sokucubungula Kwezithombe zeSussian Academy of Sciences Sciped A "amasu aphezulu okubuya kanye nemishado yawo" ngaphakathiOpto-ElectronicIntuthuko ye-chip futhiUkuxhumana kwe-fiber kwe-Optical fiber: Ukubuyekezwa. Iqembu loProfesa Khonina likaKhonina lithuthukise izinto eziningi ezihlukile zokuhluka zokwenza i-MDM esikhaleni samahhala futhiI-Fibre Optics. Kepha i-bandwidth yenethiwekhi ifana ne- "Wardrobe yakho", ayikaze ibe enkulu kakhulu, ayikaze ibe ngokwanele. Ukugeleza kwedatha kudale isidingo esiqhumayo sethrafikhi. Imiyalezo ye-imeyili emfushane iyathathelwa indawo yizithombe ezizwakalayo ezithatha i-bandwidth. Ngedatha, amanethiwekhi okusakaza wevidiyo nezwi ukuthi eminyakeni embalwa edlule ayenenqwaba ye-bandwidth, abaphathi bezokuxhumana manje sebebheke ukuthatha indlela engenakuqhathaniswa yokuhlangabezana nesidingo esingapheli se-bandwidth. Ngokusekelwe kokuhlangenwe nakho kwakhe okukhulu kule ndawo yocwaningo, uSolwazi Khonina wafingqa intuthuko yakamuva nebaluleke kakhulu emkhakheni we-Mulkexing njengoba engcono kakhulu. Izihloko ezimbozwe ekubuyekezweni zibandakanya i-WDM, PDM, SDM, i-MDM, i-OMM, kanye nobuchwepheshe obuthathu be-hybrid we-WDM-PDM, ne-WDM-MDM. Phakathi kwazo, kuphela ngokusebenzisa i-hybrid WDM-WDM-MDM Multiplexer, iziteshi ze-n × m zingatholakala ngezindlela zokuqondisa ze-NEAvelthys kanye ne-M.

Isikhungo sezinhlelo zokucubungula isithombe zeRussia Academy of Sciences (IPSI RAS, manje isigatshana se-Federal Science Research Center of the Russical Academy of Sciences of Sciences "Crystallography and Photonics") sasungulwa ngo-1988 ngesisekelo seqembu elicwaningayo eSamara State University. Iqembu liholwa nguVictor Alexandrovich Soomifer, ilungu le-Russian Academy of Science. Enye yezinkomba zokucwaninga zeqembu lokucwaninga yintuthuko yezindlela zamanani nezifundo zokuhlola zemishayo ye-laser yeziteshi eziningi. Lezi zifundo zaqala ngo-1982, lapho kwafezeka isiteshi sokuqala se-optical element (doe) ngokubambisana nethimba likaNobel Laureate ku-physics, i-Acadomian Alexander Mikhailovich Prokhorov. Eminyakeni eyalandela, ososayensi be-IPSI RAS bahlongozwa, benziwe kabusha futhi bafunda izinhlobo eziningi zezakhi zamakhompiyutha, base bebabhidlize izindlela zezwi lezigaba ezihlukile ze-loverporse. Izibonelo zifaka ama-vortices we-optical, imodi ye-lacroerrea-gauss, imodi ye-hermi-gauss, imodi ye-besmick, umsebenzi we-Zernick (wokuhlaziywa kwe-alerration), njll. Le doe, isetshenziselwa ukuhlaziya i-beam ngokususelwa kumodi ye-Optical Debompotion. Imiphumela yokulinganisa itholakala ngendlela yokuxhumanisa iziqongo ezindaweni ezithile (ama-oda wokuphazamisa) endizeni enamafutha kaJehovaUhlelo lwe-Optical. Kamuva, umgomo wawusetshenziselwa ukukhiqiza imishayo eyinkimbinkimbi, kanye nemishayo eyehlisa isithunzi emicu ye-optical, isikhala samahhala, nemidiya yeziyaluyalu usebenzisa i-doe kanye ne-spatialAmamodeli we-Optical Modulators.
