Amasu wokuphindaphinda we-Optical kanye nomshado wabo wokuxhumana kwe-on-chip ne-optical fiber

Ithimba labacwaningi likaProf. Khonina we-Institute of Image Processing Systems of the Russian Academy of Sciences lishicilele iphepha elinesihloko esithi “Optical multiplexing techniques and their marriage” in.I-Opto-ElectronicIntuthuko ye-on-chip kanyeukuxhumana kwe-fiber optical: isibuyekezo. Iqembu locwaningo likaSolwazi Khonina lenze izinto ezimbalwa ezihlukene zokubona ukuze kusetshenziswe i-MDM endaweni ekhululekile futhii-fiber optics. Kodwa i-bandwidth yenethiwekhi ifana "nekhabethe lakho", alikaze libe likhulu kakhulu, alikaze lanele. Ukugeleza kwedatha kudale isidingo esikhulu sethrafikhi. Imilayezo ye-imeyili emifushane ithathelwa indawo izithombe ezigqwayizayo ezithatha umkhawulokudonsa. Ukuze uthole idatha, ividiyo kanye namanethiwekhi okusakaza ngezwi eminyakeni embalwa nje edlule ayenomkhawulokudonsa omningi, iziphathimandla zezokuxhumana manje sezibheke ukuthatha indlela engajwayelekile yokuhlangabezana nesidingo esingapheli somkhawulokudonsa. Ngokusekelwe ekuhlangenwe nakho kwakhe okubanzi kulo mkhakha wocwaningo, uSolwazi Khonina ufingqa intuthuko yakamuva nebaluleke kakhulu emkhakheni wokuphindaphinda ngokusemandleni akhe. Izihloko ezivezwe ekubuyekezweni zifaka i-WDM, i-PDM, i-SDM, i-MDM, i-OAMM, kanye nobuchwepheshe obuyingxube obuthathu be-WDM-PDM, i-WDM-MDM, ne-PDM-MDM. Phakathi kwazo, kuphela ngokusebenzisa i-hybrid WDM-MDM multiplexer, iziteshi ze-N×M zingenziwa ngokusebenzisa ama-wavelengths angu-N kanye ne-M guide mode.

I-Institute of Image Processing Systems yeRussian Academy of Sciences (IPSI RAS, manje eyigatsha leFederal Scientific Research Center yeRussian Academy of Sciences "Crystallography and Photonics") yasungulwa ngo-1988 ngesisekelo seqembu locwaningo eSamara. State University. Ithimba liholwa nguVictor Alexandrovich Soifer, ilungu le-Russian Academy of Sciences. Enye yezinkomba zocwaningo zeqembu locwaningo ukuthuthukiswa kwezindlela zezinombolo kanye nezifundo zokuhlola zemishayo ye-laser eneziteshi eziningi. Lezi zifundo zaqala ngo-1982, lapho i-multi-channel diffracted optical element (DOE) yokuqala yenziwa ngokubambisana nethimba leNobel Laureate ku-physics, i-Academician Alexander Mikhailovich Prokhorov. Eminyakeni eyalandela, ososayensi be-IPSI RAS bahlongoza, balingisa futhi bafunda izinhlobo eziningi zezinto ze-DOE kumakhompuyutha, base bezenza ngendlela yamahologram ezigaba ezibekwe phezulu ahlukahlukene anamaphethini e-laser aguquguqukayo angashintshi. Izibonelo zifaka ama-optical vortices, imodi ye-Lacroerre-Gauss, imodi ye-Hermi-Gauss, imodi ye-Bessel, umsebenzi we-Zernick (ukuhlaziya okungahambi kahle), njll. Le DOE, eyenziwe kusetshenziswa i-electron lithography, isetshenziswa ekuhlaziyweni kwe-beam okusekelwe ekuboleni kwemodi yokubona. Imiphumela yokulinganisa itholakala ngendlela yeziqongo zokuxhumanisa ezindaweni ezithile (ama-diffraction order) endizeni ye-Fourier ye-isistimu ye-optical. Kamuva, umgomo wasetshenziselwa ukukhiqiza imishayo eyinkimbinkimbi, kanye nemishayo ehlukanisayo emiculweni yokubona, indawo yamahhala, nemidiya enesiphithiphithi kusetshenziswa i-DOE kanye nendawo.I-Optical modulators.
