URohde & Schwarz (R&S) baveze ubungqina bengcamango yenkqubo yokudlulisa idatha engenazingcingo ye-6G esekelwe kwiikhonkco zonxibelelwano ze-photonic terahertz kwiVeki yeMicrowave yaseYurophu (EuMW 2024) eParis, benceda ekuphuculeni umda wetekhnoloji engenazingcingo yesizukulwana esilandelayo. Inkqubo ye-terahertz ehlengahlengiswayo ezinzileyo kakhulu eyenziwe kwiprojekthi ye-6G-ADLANTIK isekelwe kubuchwepheshe be-frequency comb, kunye namaza okuthwala angaphezulu kakhulu kwi-500GHz.
Kwindlela eya kwi-6G, kubalulekile ukudala imithombo yokudlulisa i-terahertz enika isignali esemgangathweni ophezulu kwaye inokugubungela uluhlu olubanzi lweefrikhwensi. Ukudibanisa iteknoloji ye-optical neteknoloji ye-elektroniki yenye yeendlela zokufezekisa le njongo kwixesha elizayo. Kwingqungquthela ye-EuMW ka-2024 eParis, i-R&S ibonisa igalelo layo kuphando lwe-terahertz olusemgangathweni kwiprojekthi ye-6G-ADLANTIK. Le projekthi igxile kuphuhliso lwezixhobo zefrikhwensi ye-terahertz ezisekelwe ekuhlanganisweni kwee-photons kunye nee-electron. Ezi zixhobo ze-terahertz ezingekaphuhliswa zinokusetyenziselwa ukulinganisa okutsha kunye nokudluliselwa kwedatha ngokukhawuleza. Ezi zixhobo zinokusetyenziselwa kungekuphela nje unxibelelwano lwe-6G, kodwa kunye nokuva kunye nemifanekiso.
Le projekthi ye-6G-ADLANTIK ixhaswa yiSebe leMfundo noPhando lweSizwe laseJamani (i-BMBF) kwaye iququzelelwa yi-R&S. Amaqabane aquka i-TOPTICA Photonics AG, i-Fraunhofer-Institut HHI, i-Microwave Photonics GmbH, iYunivesithi yobuGcisa yaseBerlin kunye ne-Spinner GmbH.
Inkqubo ye-terahertz ehlengahlengiswayo ye-6G esekwe kubuchwepheshe be-photon
Ubungqina bengcamango bubonisa inkqubo ye-terahertz eqinileyo neguquguqukayo yokudluliselwa kwedatha engenazingcingo ye-6G ngokusekelwe kwi-photonic terahertz mixers ezivelisa imiqondiso ye-terahertz ngokusekelwe kubuchwepheshe be-frequency comb. Kule nkqubo, i-photodiode iguqula ngokufanelekileyo imiqondiso ye-optical beat eyenziwe yi-laser ene-optical frequency eyahlukileyo kancinci ibe yimiqondiso yombane ngenkqubo yokuxuba i-photon. Isakhiwo se-antenna esijikeleze i-photoelectric mixer siguqula i-photocurrent ejikelezayo ibe ngamaza e-terahertz. Isignali ephumayo inokuguqulwa kwaye ihlengahlengiswe kunxibelelwano olungenazingcingo lwe-6G kwaye inokulungiswa ngokulula kuluhlu olubanzi lwe-frequency. Inkqubo inokwandiswa nakwimilinganiselo yamacandelo kusetyenziswa imiqondiso ye-terahertz efunyenweyo ngokudibeneyo. Ukulinganisa kunye noyilo lwezakhiwo ze-terahertz waveguide kunye nophuhliso lwe-ultra-low phase noise photonic reference oscillators nazo ziphakathi kweendawo zokusebenza zeprojekthi.
Ingxolo yesigaba esiphantsi kakhulu senkqubo ibangelwa yi-frequency comb-locked optical frequency synthesizer (OFS) kwi-TOPTICA laser engine. Izixhobo ze-R&S eziphezulu ziyinxalenye ebalulekileyo yale nkqubo: I-R&S SFI100A wideband IF vector signal generator yenza isignali ye-baseband ye-optical modulator enesantya sokuthatha isampuli se-16GS/s. I-R&S SMA100B RF kunye ne-microwave signal generator ivelisa isignali yewotshi yesalathiso esizinzileyo kwiinkqubo ze-TOPTICA OFS. I-R&S RTP oscilloscope isampulu yesignali ye-baseband ngasemva kwe-photoconductive continuous wave (cw) terahertz receiver (Rx) ngesantya sokuthatha isampuli se-40 GS/s ukuze kuqhutyekwe phambili kwaye kususwe isignali ye-carrier frequency ye-300 GHz.
Iimfuno zebhendi ye-6G kunye neyexesha elizayo
I-6G iza kuzisa iimeko ezintsha zesicelo kushishino, kubuchwepheshe bezonyango nakubomi bemihla ngemihla. Izicelo ezifana ne-metacomes kunye ne-Extended Reality (XR) ziya kubeka iimfuno ezintsha kwizinga lokulibaziseka kunye nokudluliselwa kwedatha okungenakufezekiswa ziinkqubo zonxibelelwano zangoku. Ngelixa iNkomfa yeRadio yeHlabathi ye-International Telecommunication Union ka-2023 (WRC23) ichonge iibhendi ezintsha kwi-FR3 spectrum (7.125-24 GHz) ukuze kuphandwe ngakumbi iinethiwekhi zokuqala ze-6G zorhwebo eziza kuqaliswa ngo-2030, Kodwa ukuze kufezekiswe amandla apheleleyo e-virtual reality (VR), i-augmented reality (AR) kunye ne-mixed reality (MR), ibhendi ye-Asia-Pacific Hertz ukuya kuthi ga kwi-300 GHz nayo iya kuba yinto engabalulekanga.
