Optical multiplexing matekiniki uye muchato wavo kune-chip uye optical fiber kutaurirana

Chikwata chetsvakurudzo chaProf Khonina veInstitute of Image Processing Systems yeRussian Academy of Sciences chakaburitsa bepa rine musoro unoti “Optical multiplexing techniques and their marriage”Opto-ElectronicKufambira mberi kwe-on-chip uyeoptical fiber kutaurirana: wongororo. Boka rekutsvagisa raProfessor Khonina rakagadzira akati wandei diffractive optical zvinhu zvekushandisa MDM munzvimbo yemahara uyefiber optics. Asi network bandwidth yakafanana ne "wadhirobe yega", isina kumbonyanya kukura, haina kukwana. Kuyerera kwedata kwakagadzira kuda kunoputika kwetraffic. Mameseji mapfupi eemail ari kutsiviwa nemifananidzo yehupenyu inotora bandwidth. Kune data, vhidhiyo uye nhepfenyuro yemazwi ayo makore mashoma apfuura aive neakawanda bandwidth, zviremera zvekufonera zvino zvave kutsvaga kutora nzira isina kujairika yekusangana nekusingaperi kudiwa kwebandwidth. Zvichienderana neruzivo rwake rwakadzama munharaunda iyi yetsvagiridzo, Muzvinafundo Khonina akapfupikisa kufambira mberi kwazvino uye kwakakosha kwazvo mundima yekuwandisa sezvaaigona. Misoro yakafukidzwa muongororo iyi inosanganisira WDM, PDM, SDM, MDM, OAMM, uye matatu mahybrid matekinoroji eWDM-PDM, WDM-MDM, uye PDM-MDM. Pakati pavo, chete nekushandisa hybrid WDM-MDM multiplexer, N × M chiteshi inogona kuwanikwa kuburikidza neN wavelengths uye M gwara modes.

The Institute of Image Processing Systems yeRussia Academy yeScience (IPSI RAS, ikozvino bazi reFederal Scientific Research Center yeRussia Academy of Sciences "Crystallography uye Photonics") yakavambwa muna 1988 pahwaro hweboka rekutsvagisa kuSamara. State University. Chikwata ichi chinotungamirwa naVictor Alexandrovich Soifer, nhengo yeRussia Academy yeScience. Imwe yenzira dzekutsvagisa yeboka rekutsvagisa kuvandudzwa kwenhamba nzira uye zvidzidzo zvekuedza zveakawanda-channel laser matanda. Zvidzidzo izvi zvakatanga muna 1982, apo yekutanga multi-channel diffracted optical element (DOE) yakazadzikiswa nekubatana nechikwata cheNobel Laureate mufizikisi, Academician Alexander Mikhailovich Prokhorov. Mumakore akatevera, IPSI RAS masayendisiti akakurudzira, akateedzera uye akadzidza marudzi mazhinji ezvinhu zveDOE pamakomputa, ndokuzozvigadzira muchimiro cheakasiyana-siyana epamusoro-soro holograms ane anowirirana transverse laser mapatani. Mienzaniso inosanganisira optical vortices, Lacroerre-Gauss mode, Hermi-Gauss mode, Bessel mode, Zernick function (yekuongorora aberration), nezvimwewo. Iyi DOE, yakaitwa uchishandisa electron lithography, inoshandiswa pakuongorora danda kunobva pakuora kwe optical mode. Mhedzisiro yezviyero inowanikwa muchimiro chepamusoro pekubatanidza pane dzimwe nzvimbo (diffraction order) mundege yeFourieroptical system. Mushure meizvozvo, musimboti wakashandiswa kugadzira matanda akaomarara, pamwe nekuita demultiplexing matanda mune optical fiber, nzvimbo yemahara, uye mhirizhonga midhiya vachishandisa DOE uye spatial.Optical modulators.
