Optical multiplexing matekiniki uye muchato wavo we-on-chip uyeoptical fiber kutaurirana: wongororo

Optical multiplexing matekiniki inyaya yekukurumidzira yekutsvagisa, uye nyanzvi pasi rese dziri kuita tsvakiridzo yakadzama mundima iyi. Kwemakore, akawanda akawanda matekinoroji akadai sewavelength division multiplexing (WDM), mode division multiplexing (MDM), space division multiplexing (SDM), polarization multiplexing (PDM) uye orbital angular momentum multiplexing (OAMM) yakatsanangurwa. Wavelength division multiplexing (WDM) tekinoroji inogonesa maviri kana anopfuura masaini optical emhando dzakasiyana-siyana kuti aendeswe panguva imwe chete kuburikidza nefiber imwe chete, ichishandisa zvizere fiber yekurasikirwa kwakaderera maitiro mune yakakura wavelength renji. Dzidziso yakatanga kukurudzirwa naDelange muna 1970, uye yakanga isati yasvika 1977 iyo yekutanga tsvakurudzo yeWDM teknolojia yakatanga, iyo yakatarisa kushandiswa kwehutano hwekukurukurirana. Kubva ipapo, nekuenderera mberi kweoptical fiber, light source, photodetectornemamwe minda, kuongorora kwevanhu kweWDM tekinoroji kwakawedzerawo. Chakanakira chepolarization multiplexing (PDM) ndechekuti huwandu hwekufambiswa kwechiratidzo hunogona kuwanzwa, nekuti masaini maviri akazvimiririra anogona kugovaniswa panzvimbo ye orthogonal polarization yechiedza chimwechete chechiedza, uye nzira mbiri dzepolarization dzakapatsanurwa uye dzinozivikanwa dzakazvimiririra panzvimbo. kugamuchira kupera.

Sezvo kudiwa kwemazinga e data epamusoro kuri kuramba kuchikura, dhigirii rekupedzisira rerusununguko rwekuwanda, nzvimbo, rakadzidzwa zvakanyanya mumakore gumi apfuura. Pakati pavo, iyo mode division multiplexing (MDM) inonyanya kugadzirwa neN transmitters, iyo inowanikwa ne spatial mode multiplexer. Pakupedzisira, chiratidzo chinotsigirwa ne spatial mode chinotumirwa kune yakaderera-modhi fiber. Munguva yekuparadzira chiratidzo, mamodhi ese ari pahurefu hwakafanana anobatwa sechikamu cheSpace Division multiplexing (SDM) super chiteshi, kureva kuti anokwidziridzwa, akadzikiswa uye anowedzerwa panguva imwe chete, asingakwanise kuwana yakaparadzana modhi yekugadzirisa. MuMDM, nzvimbo dzakasiyana-siyana (kureva, maumbirwo akasiyana) epateni anopihwa kune akasiyana chiteshi. Semuyenzaniso, chiteshi chinotumirwa pamusoro pedanda relaser iro rakaumbwa kunge gonyonhatu, sikweya, kana denderedzwa. Iwo maumbirwo anoshandiswa neMDM mumashandisirwo epasirese akanyanya kuomarara uye ane akasiyana masvomhu uye emuviri maitiro. Iyi tekinoroji inopokana ndiyo yakanyanya shanduko mukufambiswa kwefiber optic data kubva kuma1980s. MDM tekinoroji inopa hurongwa hutsva hwekushandisa mamwe machaneti uye kuwedzera chinongedzo kugona uchishandisa imwechete wavelength inotakura. Orbital angular momentum (OAM) chimiro chemuviri wemafungu emagetsi umo nzira yekuparadzira inotarwa nehelical phase wavefront. Sezvo chimiro ichi chichigona kushandiswa kumisikidza akawanda akapatsanurwa chiteshi, isina waya orbital angular momentum multiplexing (OAMM) inogona kunyatso wedzera mwero wekutapurirana mune yakakwirira-kusvika-poinzi transmissions (senge wireless backhaul kana kumberi).
