Amasu wokukhanya okuningana kanye nomshado wawo we-On-Chip: Isibuyekezo

Amasu wokukhanya okuningana kanye nomshado wabo we-on-chip futhiUkuxhumana kwe-fiber kwe-Optical fiber: Ukubuyekezwa

Amasu wokushintsha okuningana ucwaningo oluphuthumayo, futhi izifundiswa emhlabeni wonke ziqhuba ucwaningo olunzulu kulo mkhakha. Kuyo yonke le minyaka, ubuchwepheshe obuningi be-Multiplex enjenge-Wavelength Division Multenxing (WDM), i-Mode Division Multenxing (MDM), i-Polarization Division MultenChing (i-PDM) kanye ne-Orbital Angular Momerem Multenxing (Omm) Ubuchwepheshe be-Wadleth Divising Multenxing (WDM) bunika amasiginali amabili noma amaningi we-wavelength ahlukene ukuze adluliselwe ngasikhathi sinye ngokusebenzisa i-fiber eyodwa, esebenzisa ngokugcwele izici eziphansi zokulahlekelwa okuphansi kububanzi obuncane be-wavelth. Umbono wawuhlongozwe okokuqala ngo-1970, futhi akubanga kuze kube ngu-1977 ukuthi ucwaningo lwesisekelo lwe-WDM Technology lwaqala, olugxile ekusetshenzisweni kwamanethiwekhi okuxhumana. Kusukela lapho, ngokuthuthuka okuqhubekayo kwei-fiber ye-Optical, Umthombo Okhanyayo, I-PhotoDETETETETECETETETkanye nezinye izinkambu, ukuhlola kwabantu ubuchwepheshe be-WDM nakho kusheshisile. Inzuzo ye-Polarization Multenxing (PDM) ukuthi inani lokudluliselwa kwesiginali lingaphindwa, ngoba amasignali amabili azimele angasatshalaliswa esikhundleni se-orthogonal polarization of snowle

Njengoba isidingo samanani entengo yedatha eqhubekayo eqhubeka nokukhula, izinga lokugcina lenkululeko yokuthola inkululeko, isikhala, selifundwe kakhulu eminyakeni eyishumi edlule. Phakathi kwazo, imodi yokuhlukaniswa ngemodi (i-MDM) yenziwa ikakhulukazi yi-N Transmitters, etholakala ngemodi ye-Spatial Multiplexer. Ekugcineni, isiginali esekelwa yimodi ye-Spatial idluliselwa kwi-fiber yemodi ephansi. Ngesikhathi sokusakazwa kwesiginali, zonke izindlela ezise-wavelth efanayo ziphathwa njengeyunithi lesiteshi esikhulu se-Space Divising MultenityXing (SDM) isiteshi esikhulu, okusho ukuthi anwebekile, ngaphandle kokuthola ukucubungula okuhlukile. E-MDM, ama-contours ahlukene we-spatial (okungukuthi, ukwakheka okuhlukile) kwephethini abelwe eziteshini ezahlukene. Isibonelo, isiteshi sithunyelwa ngaphezulu kogongolo lwe-laser olubunjwe njengonxantathu, isikwele, noma umbuthano. Amajamo asetshenziswa yi-MDM ku-Real-World Application ankimbinkimbi kakhulu futhi abe nezimpawu ezihlukile nezibalo. Lobu buchwepheshe buyimpikiswano eguquguqukayo kakhulu ekuhanjisweni kwedatha ye-fiber i kusukela ngo-1980s. Ubuchwepheshe be-MDM bunikeza isu elisha lokusebenzisa iziteshi eziningi kanye nokukhulisa umthamo wokuxhumanisa usebenzisa isithwali esilinganayo. I-Orbital angular amentum (OAM) iyisici esingokomzimba samagagasi kagesi lapho indlela yokusakazwa inqunywa yi-war war war warwer. Njengoba lesi sici singasetshenziswa ukusungula iziteshi eziningi ezihlukene, i-wireless angular angular Momerem MultenityXing (OIMM) ingandisa ngempumelelo isilinganiso sokudlulisa ekuhanjisweni okuphezulu (njengokudluliselwa kwe-backaul e-wireless noma phambili).
