Maitiro ekuwedzera maoptical uye kurongeka kwawo kune on-chip: ongororo

Matekiniki eOptical multiplexing uye kurongeka kwawo kune on-chip uyekutaurirana kwefiber ye optical: ongororo

Matekiniki eOptical multiplexing inyaya yekutsvagisa inoda kukurumidzirwa, uye nyanzvi pasi rese dziri kuita tsvakiridzo yakadzama mundima iyi. Mumakore apfuura, matekinoroji mazhinji emultiplex akadai sewavelength division multiplexing (WDM), mode division multiplexing (MDM), space division multiplexing (SDM), polarization multiplexing (PDM) uye orbital angular momentum multiplexing (OAMM) akakurudzirwa. Tekinoroji yeWavelength division multiplexing (WDM) inoita kuti zviratidzo zviviri kana kupfuura zvema wavelength akasiyana zvitumirwe panguva imwe chete kuburikidza nefiber imwe chete, zvichishandisa zvizere hunhu hwe fiber hwakaderera mukureba kwewavelength. Dzidziso iyi yakatanga kukurudzirwa naDelange muna 1970, uye zvakatotanga muna 1977 apo tsvakiridzo yekutanga yetekinoroji yeWDM yakatanga, iyo yakatarisana nekushandiswa kwema network ekutaurirana. Kubva ipapo, nekuvandudzwa kuri kuramba kuchienderera mberi kwefaibha yemaziso, chiedza chinobva, mudziyo wekuona fotonedzimwe nzvimbo, kuongorora kwevanhu tekinoroji yeWDM kwakawedzerawo. Kubatsira kwe polarization multiplexing (PDM) ndekwekuti huwandu hwekutumira masaini hunogona kuwanda, nekuti masaini maviri akazvimiririra anogona kugoverwa panzvimbo ye orthogonal polarization yechiedza chimwe chete, uye nzira mbiri dze polarization dzinoparadzaniswa uye dzinozivikanwa dzakazvimirira pamugumo wekugamuchira.

Sezvo kudiwa kwehuwandu hwedata hwakakwira kuri kuramba kuchikura, mwero wekupedzisira werusununguko rwemultiplexing, nzvimbo, wakadzidzwa zvakanyanya mumakore gumi apfuura. Pakati pawo, mode division multiplexing (MDM) inonyanya kugadzirwa nemaN transmitters, ayo anowanikwa ne spatial mode multiplexer. Pakupedzisira, chiratidzo chinotsigirwa ne spatial mode chinotumirwa kune low-mode fiber. Munguva yekuparadzirwa kwesignal, mamodhi ese ari pawavelength imwechete anobatwa seyuniti yeSpace Division multiplexing (SDM) super channel, kureva kuti anowedzerwa, anoderedzwa uye anowedzerwa panguva imwe chete, pasina kukwanisa kuwana nzira dzakasiyana dzekugadzirisa. MuMDM, ma contour akasiyana enzvimbo (ndiko kuti, maumbirwo akasiyana) epattern anopihwa kuma channel akasiyana. Semuenzaniso, channel inotumirwa pamusoro pe laser beam yakagadzirwa se triangle, sikweya, kana denderedzwa. Maumbirwo anoshandiswa neMDM mumashandisirwo chaiwo akaomarara uye ane hunhu hwakasiyana hwemasvomhu nemuviri. Iyi tekinoroji ingangove ndiyo budiriro huru mukutapurirana data re fiber optic kubvira kuma1980. Tekinoroji yeMDM inopa nzira itsva yekushandisa nzira dzakawanda uye kuwedzera kugona kwekubatanidza uchishandisa imwe chete wavelength carrier. Orbital angular momentum (OAM) imhando yemagetsi yemafungu emagetsi umo nzira yekupararira inosarudzwa ne helical phase wavefront. Sezvo chimiro ichi chichigona kushandiswa kugadzira nzira dzakasiyana siyana, wireless orbital angular momentum multiplexing (OAMM) inogona kuwedzera zvinobudirira mwero wekutumira mu high-to-point transmissions (senge wireless backhaul kana forward).
