Maitiro ekuwedzera maoptical uye kubatana kwawo pakutaurirana kwe-on-chip ne optical fiber

Chikwata chekutsvagisa chaProf. Khonina kubva kuInstitute of Image Processing Systems yeRussian Academy of Sciences chakaburitsa bepa rine musoro unoti “Optical multiplexing techniques and their marriage” muOpto-ElectronicKufambira mberi kwe on-chip uyekutaurirana kwefiber ye optical: ongororo. Boka rekutsvagisa raPurofesa Khonina rakagadzira zvinhu zvakasiyana-siyana zvinoparadzanisa optical zvekushandisa MDM munzvimbo yakasununguka uyefiber opticsAsi bandwidth yenetwork yakaita se "wardrobe yako", haimbove yakakura zvakanyanya, haimbove yakakwana. Kufamba kwedata kwagadzira kudiwa kukuru kwetraffic. Maemail mapfupi ari kutsiviwa nemifananidzo yeanimated inotora bandwidth. Kune network dzedata, mavhidhiyo uye voice broadcast idzo makore mashoma apfuura dzaive nebandwidth yakawanda, vakuru vekutaurirana vari kutsvaga kutora nzira isina kujairika yekusangana nekudiwa kusingaperi kwebandwidth. Zvichibva paruzivo rwavo rwakakura munharaunda iyi yekutsvagisa, Purofesa Khonina akapfupikisa kufambira mberi kwazvino uye kwakakosha mumunda we multiplexing sezvaaigona. Misoro yakafukidzwa muongororo iyi inosanganisira WDM, PDM, SDM, MDM, OAMM, uye matekinoroji matatu ehybrid eWDM-PDM, WDM-MDM, uye PDM-MDM. Pakati padzo, chete nekushandisa hybrid WDM-MDM multiplexer, N×M channels dzinogona kuwanikwa kuburikidza neN wavelengths uye M guide modes.

Sangano reInstitute of Image Processing Systems reRussian Academy of Sciences (IPSI RAS, iro rava bazi reFederal Scientific Research Center yeRussian Academy of Sciences “Crystallography and Photonics”) rakavambwa muna 1988 zvichibva paboka revaongorori paSamara State University. Chikwata ichi chinotungamirwa naVictor Alexandrovich Soifer, nhengo yeRussian Academy of Sciences. Imwe yenzira dzekutsvagisa dzeboka revaongorori ndeyekugadzirwa kwenzira dzekuverenga nhamba uye zvidzidzo zvekuyedza zvemwaranzi yelaser yakawanda. Zvidzidzo izvi zvakatanga muna 1982, apo chinhu chekutanga che multi-channel diffracted optical element (DOE) chakaitwa pamwe chete nechikwata cheNobel Laureate mufizikisi, Academician Alexander Mikhailovich Prokhorov. Mumakore akatevera, masayendisiti eIPSI RAS akakurudzira, akatevedzera uye akadzidza marudzi mazhinji eDOE elements pamakombiyuta, uye akazozvigadzira muchimiro che superimposed phase holograms dzakasiyana-siyana dzine ma transverse laser patterns akafanana. Mienzaniso inosanganisira optical vortices, Lacroerre-Gauss mode, Hermi-Gauss mode, Bessel mode, Zernick function (yekuongorora kweaberration), nezvimwewo. Iyi DOE, yakagadzirwa uchishandisa electron lithography, inoshandiswa pakuongorora beam zvichibva pakupatsanurwa kwe optical mode. Mhedzisiro yekuyera inowanikwa muchimiro che correlation peaks pane dzimwe nzvimbo (diffraction orders) muFourier plane yesisitimu yemazisoZvadaro, musimboti wacho wakashandiswa kugadzira matanda akaomarara, pamwe nekubvisa matanda akawanda mufibers dze optical, nzvimbo yakasununguka, uye turbulent media uchishandisa DOE uye spatial.Mamodulator emaziso.
