Iindlela zokudibanisa i-optical multiplexing kunye nolwalamano lwazo lonxibelelwano lwe-on-chip kunye ne-optical fiber

Iqela lophando likaNjingalwazi Khonina ovela kwi-Institute of Image Processing Systems ye-Russian Academy of Sciences lipapashe iphepha elinesihloko esithi “Optical multiplexing techniques and their marriage” kwiI-Opto-ElectronicInkqubela phambili kwi-on-chip kunyeunxibelelwano lwefayibha ye-optical: uphononongo. Iqela lophando likaNjingalwazi uKhonina liphuhlise izinto ezininzi ze-diffractive optical zokuphumeza i-MDM kwindawo ekhululekileyo kunyei-fiber opticsKodwa i-bandwidth yenethiwekhi ifana "nekhabhathi yakho", ayikaze ibe nkulu kakhulu, ayikaze yanele. Ukuhamba kwedatha kudale imfuno enkulu yethrafikhi. Imiyalezo emifutshane ye-imeyile ithathelwa indawo yimifanekiso eshukumayo ethatha i-bandwidth. Kwiinethiwekhi zedatha, ividiyo kunye nokusasazwa kwelizwi ezazineminyaka embalwa eyadlulayo zine-bandwidth eninzi, abasemagunyeni bezonxibelelwano ngoku bajonge ukuthatha indlela engaqhelekanga yokuhlangabezana nemfuno engapheliyo ye-bandwidth. Ngokusekelwe kumava akhe amaninzi kule ndawo yophando, uNjingalwazi uKhonina ushwankathele inkqubela phambili yamva nje neyona ibalulekileyo kwicandelo le-multiplexing kangangoko anako. Izihloko ezigutyungelwe kuphononongo ziquka i-WDM, i-PDM, i-SDM, i-MDM, i-OAMM, kunye neetekhnoloji ezintathu ze-hybrid ze-WDM-PDM, i-WDM-MDM, kunye ne-PDM-MDM. Phakathi kwazo, kuphela ngokusebenzisa i-multiplexer ye-hybrid WDM-MDM, iitshaneli ze-N×M zinokufezekiswa ngokusebenzisa ii-wavelengths ze-N kunye neendlela zesikhokelo se-M.

I-Institute of Image Processing Systems ye-Russian Academy of Sciences (i-IPSI RAS, ngoku isebe le-Federal Scientific Research Center ye-Russian Academy of Sciences “Crystallography and Photonics”) yasungulwa ngo-1988 ngesiseko seqela lophando kwiYunivesithi yaseSamara State. Eli qela likhokelwa nguVictor Alexandrovich Soifer, ilungu le-Russian Academy of Sciences. Enye yeendlela zophando zeqela lophando kukuphuhliswa kweendlela zamanani kunye nezifundo zovavanyo lwe-multi-channel laser beams. Ezi zifundo zaqala ngo-1982, xa i-multi-channel diffracted optical element yokuqala (DOE) yaqaliswa ngentsebenziswano neqela le-Nobel Laureate kwi-physics, i-Academician uAlexander Mikhailovich Prokhorov. Kwiminyaka eyalandelayo, izazinzulu ze-IPSI RAS zacebisa, zalinganisa kwaye zafunda iintlobo ezininzi zezinto ze-DOE kwiikhompyutha, zaza emva koko zazenza ngendlela yee-holograms ezahlukeneyo zesigaba ezibekwe ngaphezulu kunye neepateni ze-laser ezijikelezayo ezihambelanayo. Imizekelo ibandakanya ii-vortices ze-optical, imo ye-Lacroerre-Gauss, imo ye-Hermi-Gauss, imo ye-Bessel, umsebenzi we-Zernick (wohlalutyo lwe-aberration), njl. Le DOE, eyenziwe kusetyenziswa i-electron lithography, isetyenziswa kuhlalutyo lwe-beam olusekelwe ekuqhekekeni kwemo ye-optical. Iziphumo zokulinganisa zifunyanwa ngendlela yeencopho zokunxibelelana kwiindawo ezithile (ii-diffraction orders) kwi-Fourier plane yeinkqubo ye-opticalEmva koko, lo mgaqo wasetyenziswa ukuvelisa imisebe entsonkothileyo, kunye nokususa imisebe emininzi kwimicu ye-optical, indawo ekhululekileyo, kunye nemidiya ephazamisayo kusetyenziswa i-DOE kunye ne-spatialIimodulators zokukhanya.
