Mekhoa ea Optical multiplexing le lenyalo la bona bakeng sa puisano ea on-chip le optical fiber

Sehlopha sa lipatlisiso sa Prof. Khonina ho tsoa ho Institute of Image Processing Systems of the Russian Academy of Sciences se phatlalalitse pampiri e nang le sehlooho se reng “Optical multiplexing techniques and their marriage”Opto-ElectronicTsoelopele bakeng sa on-chip lepuisano ea fiber ea optical: tlhahlobo.Sehlopha sa lipatlisiso sa Moprofesa Khonina se thehile likarolo tse 'maloa tse fapaneng tsa optical bakeng sa ho kenya ts'ebetsong MDM sebakeng sa mahala lefiber optics.Empa marang-rang a marang-rang a tšoana le "liaparo tsa hae", ha ho mohla li kholo haholo, ha ho mohla li lekaneng.Phallo ea data e bakile tlhokahalo e matla ea sephethephethe.Melaetsa e khuts'oane ea lengolo-tsoibila e nkeloa sebaka ke litšoantšo tse phelisang tse nkang marang-rang.Bakeng sa marang-rang a data, a video le a lentsoe ao lilemong tse 'maloa tse fetileng a neng a e-na le bandwidth e ngata, balaoli ba likhokahano ba se ba batla ho nka mokhoa o sa tloaelehang oa ho fihlela tlhoko e sa feleng ea bandwidth.Ho itšetlehile ka phihlelo ea hae e pharaletseng sebakeng sena sa lipatlisiso, Moprofesa Khonina o ile a akaretsa tsoelo-pele ea morao-rao le ea bohlokoa ka ho fetisisa lefapheng la multiplexing ka hohle kamoo a ka khonang.Lihlooho tse boletsoeng tlhahlobisong li kenyelletsa WDM, PDM, SDM, MDM, OAMM, le mekhoa e meraro e nyalisitsoeng ea WDM-PDM, WDM-MDM, le PDM-MDM.Har'a bona, ke feela ka ho sebelisa hybrid WDM-MDM multiplexer, liteishene tsa N× M li ka bonoa ka mekhoa ea N wavelengths le M guide.

Institute of Image Processing Systems ea Russian Academy of Sciences (IPSI RAS, eo hona joale e leng lekala la Federal Scientific Research Center ea Russia Academy of Sciences "Crystallography le Photonics") e thehiloe ka 1988 motheong oa sehlopha sa lipatlisiso Samara. Univesithi ea Naha.Sehlopha se etelletsoe pele ke Victor Alexandrovich Soifer, setho sa Russian Academy of Sciences.E 'ngoe ea litataiso tsa lipatlisiso tsa sehlopha sa lipatlisiso ke nts'etsopele ea mekhoa ea lipalo le lithuto tsa liteko tsa maballo a laser a likanale tse ngata.Lithuto tsena li qalile ka 1982, ha mochine oa pele oa li-multi-channel diffracted optical element (DOE) o phethahala ka ts'ebelisano le sehlopha sa Nobel Laureate ea fisiks, Academician Alexander Mikhailovich Prokhorov.Lilemong tse ileng tsa latela, bo-ramahlale ba IPSI RAS ba ile ba sisinya, ba etsisa le ho ithuta mefuta e mengata ea likarolo tsa DOE ka har'a likhomphutha, 'me ba li etsa ka mokhoa oa li-hologram tse fapaneng tse pharalletseng tse nang le li-laser tse sa fetoheng.Mehlala e kenyelletsa li-vortices tsa optical, mokhoa oa Lacroerre-Gauss, mokhoa oa Hermi-Gauss, mokhoa oa Bessel, mosebetsi oa Zernick (bakeng sa tlhahlobo ea aberration), joalo-joalo.Liphetho tsa tekanyo li fumanoa ka mokhoa oa litlhoro tsa khokahano lintlheng tse itseng (litaelo tsa phapano) sefofaneng sa Fourier satsamaiso ea mahlo.Kamora moo, molao-motheo ona o ile oa sebelisoa ho hlahisa maballo a rarahaneng, hammoho le maballo a demultiplexing ka likhoele tsa optical, sebaka sa mahala, le mecha ea litaba e ferekaneng e sebelisang DOE le sebaka.Li-modulator tsa mahlo.
