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 tšebetsong 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, feela ka ho sebelisa multiplexer e nyalisitsoeng ea WDM-MDM, liteishene tsa N× M li ka bonoa ka N wavelengths le mekhoa ea tataiso ea M.

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 tšebelisano 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-modulators tsa mahlo.
