Uhlobo olusha lweTerahertz Multiplexer luphindwe kabili umthamo wedatha nokuthuthuka okuthuthuke kakhulu kwe-6G nge-bandwidth engakaze ibonwe kanye nokulahleka kwedatha okuphansi.

Ukuxhumana okungenantambo kwesizukulwane, okumelelwa yiTerrahertz Technology, izithembiso zokuguqula ukuhanjiswa kwedatha.
Lezi zinhlelo zisebenza kumafrikhwensi eTerahertz, enikeza umkhawulokudonsa ongafani nokudluliselwa kwedatha okusheshayo nokuxhumana. Kodwa-ke, ukuqaphela ngokuphelele le mikhono, izinselelo zezobuchwepheshe ezibalulekile kufanele zinqotshwe, ikakhulukazi ekuphatheni nasekusebenzeni ngempumelelo ngempumelelo.
Intuthuko ehlabayo ibhekane nale nselelo: I-Ultra-Wideind yokuqala ehlanganiswe ne-TeraRertz Polarization (de) Multentexer) itholakale endaweni yesikhulumi se-silicon yamahhala.
Lo mklamo omusha uhlose i-sub-terahertz j band (220-330 GHz) futhi ihlose ukuguqula ukuxhumana kwe-6g nangale kwalokho. Idivayisi ngempumelelo iphindwe kabili kwedatha yedatha ngenkathi igcina isilinganiso esiphansi sokulahleka kwedatha, iveza indlela yamanethiwekhi angenantambo asebenzayo futhi athembekile.
Iqembu ngemuva kwale mpisi lifaka uSolwazi Nayawat Nayayachwemnnanwork e-University of Elelaide show kagesi nobunjiniyela bemishini, uDkt. Weijie Gaao, manje uProfessor Masayuki Fujita.
USolwazi NanaAchnankulu, "I-Polarization Multenxer ehlongozwayo ivumela imifudlana eminingi yedatha ukuthi idluliselwe ngasikhathi sinye phakathi kwemvamisa efanayo, ngempumelelo iphindwe kabili yedatha." I-bandwidth ehlobene itholwe yidivayisi ayikaze ibonwe kunoma yiliphi ibanga lemvamisa, elimele ukugxuma okukhulu kwabaningi abahlanganisiwe.
Ama-polarization Multizxers abalulekile ekuxhumaneni kwanamuhla njengoba benika amandla amasiginali amaningi ukwaba ibhendi efanayo yemvamisa, ethuthukisa kakhulu umthamo wesiteshi.
Idivaysi entsha ifinyelela lokhu ngokusebenzisa izithandani eziqondakalayo ze-anisotropic ezisebenzayo. Lezi zingxenye zithuthukisa ubumbano lwe-brefrization, okuholele ekulinganiselweni okuphezulu kokuqothulwa kombala (ngamunye) kanye nezimpawu ezibanzi ze-bandwidth-key zezinhlelo zokuxhumana zeTerahertz.
Ngokungafani nemiklamo yendabuko ethembela kuma-wave we-asymmetric athembekile athembekile futhi athembekile, i-Multiplexer entsha isebenzisa ukungcola kwe-anotropic ngokuncika imvamisa imvamisa. Le ndlela ithola ngokuphelele i-bandwidth ezanele enikezwe izithandani ze-conical.
Umphumela uba umkhawulokudonsa we-fractional esondele ku-40%, isilinganiso ngasinye esidlula nge-20 dB angama-20, kanye nokulahleka kokufakwa okuncane okucishe kube yi-1 dB. Lawa ma-metric asebenza kanzima adlula lezo zemiklamo ekhona ye-optical ne-microwave, evame ukuhlushwa umkhawulokudonsa omncane nokulahlekelwa okuphezulu.
Umsebenzi weqembu lokucwaninga awugcini nje ngokuqhakambisa ukusebenza kahle kwezinhlelo zeTerahertz kodwa futhi ubeka isisekelo senkathi entsha ekuxhumaneni okungenantambo. UDkt Gao waphawula, "lokhu okusha kungumshayeli osemqoka ekuvuleni amandla okuxhumana kweTerahertz." Izicelo zifaka ukusakazwa kwevidiyo okunencazelo ephezulu, okungokoqobo okungathandwa kwabathelisi esikubona, namanethiwekhi weselula wesizukulwane esilandelayo afana ne-6G.
Izisombululo zokulawulwa kwe-Teraring Terarization zendabuko, njenge-Orthogonal Mode Transcucers (ama-OMTS) ngokususelwa kuma-waveguides wensimbi exande, abhekane nemikhawulo ebalulekile. Isipiliyoni se-waveguides sensimbi sandise ukulahleka kwe-Ohmic ngamaza aphezulu, futhi izinqubo zazo zokukhiqiza ziyinkimbinkimbi ngenxa yezidingo zejometri eziqinile.
Abalingisi abaningi be-polarization, kufaka phakathi labo abasebenzisa ama-mach-Zehnder interrometers noma amakristalu e-Photonic, nikeza ukuxhumeka okungcono nokulahleka okuphansi kepha kuvame ukudinga ukuhweba phakathi kwe-bandwidth, ukuhlanganiswa, kanye nokukhiqiza ubunzima.
Izithandani eziqondisayo zisetshenziswa kabanzi ezinhlelweni ze-optical futhi zidinga ukuqina kwe-polaristization ukuzuza usayizi ohlangene kanye nokuphakama ngakunye. Kodwa-ke, zikhawulelwe yi-bandwidth emincane nokuzwela kokukhiqiza ukubekezelelana.
I-Multiplexer entsha ihlanganisa izinzuzo ze-conical okuqondayo izithandani kanye nokuqothuka okusebenzayo okusebenzayo, ukunqoba lokhu kulinganiselwa. I-Anisotropic Clodsing ikhombisa i-birefringlence ebalulekile, iqinisekisa ukuphakama ngaphesheya kwe-bandwidth ebanzi. Lesi simiso somklamo simaka ukusuka ezindleleni zendabuko, sinikeze isixazululo esilinganiselwe futhi esisebenzayo sokuhlanganiswa kweTerahertz.
Ukuqinisekiswa kokuhlola kwe-mopxer kuqinisekiswe ukusebenza kwayo okuhlukile. Idivayisi isebenza kahle ebangeni lama-225-330 GHZ, ifinyelela i-bandwidth ye-Fractional of 37.8% ngenkathi igcina ngenhla ngenhla kwe-20 dB ngenhla kwe-20 dB. Ubukhulu bawo obuhlangene kanye nokuhambisana nezinqubo ezijwayelekile zokukhiqiza zenza ilungele ukukhiqizwa kwesisindo.
UDkt Gao waphawula, "Lokhu okusha akugcini nje kukhulisa ukusebenza kahle kwezinhlelo zokuxhumana zeTerahertz kepha kwaveza indlela yamanethiwekhi angenantambo anamandla futhi anokwethenjelwa."
Izicelo ezingaba khona zalobu buchwepheshe zinwebeka ngaphezu kwezinhlelo zokuxhumana. Ngokwenza ngcono ukusetshenziswa kwe-spectrum, i-Multiplexer ingashayela intuthuko emikhakheni efana ne-radar, imaging, kanye ne-inthanethi yezinto. "Kungakapheli iminyaka eyishumi, silindele ukuthi lobu buchwepheshe be-terahertz bamukelwe kabanzi futhi bahlanganiswe kuyo yonke imboni ehlukahlukene," kusho uSolwazi Nayachimnankin.
I-Multiplexer nayo ingahlanganiswa nomthungo namadivayisi we-beangforming yangaphambili athuthukiswe yiqembu, enika amandla ukusebenza kwezokuxhumana okuthuthukile endaweni ehlanganisiwe. Lokhu kuhambisana kuqokomisa ukuguquguquka okuguquguqukayo kanye nokukhubazeka kwepulatifomu ye-waveguvide ye-waveguide esebenza ngempumelelo ye-medium-clad dielectric.
Ukutholwa kweqembu kweqembu kushicilelwe egazini laseLaser & Reviews, kugcizelela ukubaluleka kwawo ekuthuthukiseni ubuchwepheshe be-terahertz teranci. USolwazi Fujita waphawula, "ngokunqoba izithiyo zobuchwepheshe ezibucayi, lokhu okusha kulindeleke ukuthi kuvuse umsebenzi kanye nomsebenzi wokucwaninga emkhakheni."
Abaphenyi balindele ukuthi umsebenzi wabo uzokhuthaza izinhlelo zokusebenza ezintsha kanye nokuthuthuka okwengeziwe kwezobuchwepheshe eminyakeni ezayo, kuholela ekuhlolweni kwezentengiso nemikhiqizo.
Le nto Multiplecer imele isinyathelo esibalulekile phambili ekuvuleni amandla okuxhumana kweTerahertz. Ibeka indinganiso entsha yamadivayisi we-Terahertz ahlanganisiwe anama-metric awo angabe eyenziwe asebenze.
Njengokufunwa kwesivinini esiphakeme, amanethiwekhi okuxhumana aphezulu aphezulu ayaqhubeka nokukhula, ubumbano olunjalo luzodlala indima ebalulekile ekubumbeni ikusasa lobuchwepheshe obungenawaya.
