Uburyo bwiza bwo guhuza ibintu hamwe nubukwe bwabo kuri chip hamwe na fibre optique

Itsinda ry’ubushakashatsi bwa Prof. Khonina wo mu kigo cy’ubushakashatsi bwo gutunganya amashusho y’ishuri ry’ubumenyi ry’Uburusiya ryasohoye urupapuro rwiswe “Optical multiplexing tekinike n’ubukwe bwabo” muriOpto-ElectronicIterambere kuri on-chip naitumanaho rya fibre optique: isubiramo. Itsinda ry’ubushakashatsi bwa Porofeseri Khonina ryateguye ibintu byinshi bitandukanya optique yo gushyira mu bikorwa MDM mu busa kandifibre optique. Ariko umuyoboro mugari ni nka "wardrobe wenyine", ntabwo bigeze binini cyane, ntibihagije. Amakuru atemba yatumije ibintu biturika byimodoka. Ubutumwa bugufi bwa imeri busimburwa namashusho ya animasiyo afata umurongo mugari. Kumakuru, videwo n'amajwi byogutangaza amajwi mumyaka mike ishize gusa byari bifite umurongo mwinshi, abashinzwe itumanaho ubu barashaka gufata inzira idasanzwe kugirango bahaze ibyifuzo bitagira ingano. Ashingiye ku bunararibonye afite muri uru rwego rw’ubushakashatsi, Porofeseri Khonina yavuze muri make iterambere rigezweho kandi ry’ingenzi mu rwego rwo kugwiza uko ashoboye. Ingingo zivugwa muri iri suzuma zirimo WDM, PDM, SDM, MDM, OAMM, hamwe na tekinoroji ya Hybrid itatu ya WDM-PDM, WDM-MDM, na PDM-MDM. Muri byo, gusa ukoresheje imvange ya WDM-MDM multiplexer, imiyoboro ya N × M irashobora kugerwaho hifashishijwe uburebure bwa N na M kuyobora.

Ikigo gishinzwe gutunganya amashusho y’ishuri ry’ubumenyi ry’Uburusiya (IPSI RAS, ubu ni ishami ry’ikigo cy’ubushakashatsi cya siyansi y’ubumenyi cy’ikigo cy’ubumenyi cy’Uburusiya cyitwa “Crystallography na Photonics”) cyashinzwe mu 1988 hashingiwe ku itsinda ry’ubushakashatsi i Samara. Kaminuza ya Leta. Iri tsinda riyobowe na Victor Alexandrovich Soifer, umunyamuryango w’ishuri ry’ubumenyi ry’Uburusiya. Bumwe mu buyobozi bwubushakashatsi bwitsinda ryubushakashatsi nugutezimbere uburyo bwimibare nubushakashatsi bwubushakashatsi bwibice byinshi bya laser. Ubu bushakashatsi bwatangiye mu 1982, igihe ikintu cya mbere cyatandukanyaga ibintu bya optique (DOE) cyagaragaye ku bufatanye nitsinda ryatsindiye igihembo cyitiriwe Nobel muri fiziki, umunyeshuri Alexander Mikhailovich Prokhorov. Mu myaka yakurikiyeho, abahanga ba IPSI RAS basabye, bigana kandi biga ubwoko bwinshi bwibintu bya DOE kuri mudasobwa, hanyuma babihimba muburyo bwa hologramma zitandukanye zirengeje urugero hamwe na lazeri ihindagurika. Ingero zirimo vortices optique, uburyo bwa Lacroerre-Gauss, uburyo bwa Hermi-Gauss, uburyo bwa Bessel, imikorere ya Zernick (kubisesengura rya aberration), nibindi. Ibisubizo byo gupima biboneka muburyo bwo guhuza impinga ahantu runaka (ordre de diffaction) mu ndege ya Fourier yaSisitemu. Icyakurikiyeho, ihame ryakoreshejwe mukubyara ibiti bigoye, kimwe no kumurika ibiti muri fibre optique, umwanya wubusa, nibitangazamakuru bivuruguta ukoresheje DOE nu mwanyaAbayobora neza.
