Sadarwar mara waya ta zamani mai zuwa, wanda fasahar terahertz ke wakilta, yayi alƙawarin sauya watsa bayanai.
Waɗannan tsarin suna aiki a mitoci na terahertz, suna ba da bandwidth mara misaltuwa don watsa bayanai cikin sauri da sadarwa. Koyaya, don fahimtar wannan yuwuwar gabaɗaya, dole ne a shawo kan manyan ƙalubalen fasaha, musamman a cikin sarrafawa da amfani da su yadda ya kamata.
Babban ci gaban ƙasa ya magance wannan ƙalubalen: na farko ultra-wideband hadedde terahertz polarization (de) multiplexer an gano shi akan dandamalin silicon mara amfani.
Wannan sabon ƙirar ƙira yana hari ga ƙungiyar sub-terahertz J (220-330 GHz) kuma yana da nufin canza sadarwa don 6G da bayansa. Na'urar ta ninka ƙarfin bayanai yadda ya kamata yayin da take riƙe ƙarancin asarar bayanai, tana ba da hanya don ingantaccen hanyoyin sadarwa mara igiyar ruwa mai sauri kuma abin dogaro.
Tawagar da ke bayan wannan ci gaba ta hada da Farfesa Withawat Withayachumnankul daga Makarantar Lantarki da Injiniyan Injiniya ta Jami'ar Adelaide, Dokta Weijie Gao, wanda yanzu shi ne mai binciken digiri na biyu a Jami'ar Osaka, da Farfesa Masayuki Fujita.
Farfesa Withayachumnankul ya bayyana cewa, "Tsarin polarization multiplexer yana ba da damar watsa bayanai da yawa a lokaci guda a cikin rukunin mitar guda ɗaya, tare da ninka ƙarfin bayanai yadda ya kamata." Dangantakar bandwidth da aka samu ta na'urar ba a taɓa yin irin ta ba a kowane kewayon mitar, yana wakiltar babban tsalle don haɗakarwa masu yawa.
Polarization multiplexers suna da mahimmanci a cikin sadarwar zamani yayin da suke ba da damar sigina da yawa don raba rukunin mitar guda ɗaya, suna haɓaka ƙarfin tashar sosai.
Sabuwar na'urar ta cim ma hakan ta hanyar amfani da ma'auran ra'ayi na conical da ma'auni mai tasiri na anisotropic. Waɗannan abubuwan da aka gyara suna haɓaka birefringence na polarization, yana haifar da babban rabo na ɓarna polarization (PER) da faɗin bandwidth-maɓalli na ingantaccen tsarin sadarwa na terahertz.
Ba kamar ƙirar al'ada waɗanda ke dogaro da ƙaƙƙarfan jagororin igiyoyin asymmetric na dogaro da mitar ba, sabon Multixer yana ɗaukar anisotropic cladding tare da dogaro kaɗan kaɗan. Wannan tsarin yana ba da cikakken amfani da isassun bandwidth da ma'auratan conical suka bayar.

Ayyukan ƙungiyar bincike ba wai kawai haɓaka ingantaccen tsarin terahertz bane amma har ma yana shimfida tushen sabon zamani na sadarwa mara waya. Dokta Gao ya lura, "Wannan sabon abu shine babban direba don buɗe yuwuwar sadarwar terahertz." Aikace-aikace sun haɗa da babban ma'anar yawo na bidiyo, haɓakar gaskiya, da cibiyoyin sadarwar wayar hannu na gaba kamar 6G.
Maganganun sarrafa polarization na gargajiya na terahertz, kamar masu canza yanayin yanayin orthogonal (OMTs) dangane da jagororin raƙuman ƙarfe na rectangular, suna fuskantar ƙayyadaddun iyaka. Ƙarfe yana fuskantar ƙaƙƙarfan asarar ohmic a mitoci mafi girma, kuma tsarin ƙirar su yana da sarƙaƙƙiya saboda ƙaƙƙarfan buƙatun geometric.
