Ua hōʻike ʻo Rohde & Schwarz (R&S) i kahi hōʻoia-o-ka manaʻo no kahi ʻōnaehana hoʻoili ʻikepili uea ʻole 6G e pili ana i nā loulou kamaʻilio photonic terahertz ma ka European Microwave Week (EuMW 2024) ma Palisa, e kōkua ana i ka hoʻolaha ʻana i ka palena o nā ʻenehana uea ʻole o ka hanauna e hiki mai ana. ʻO ka ʻōnaehana terahertz tunable ultra-stable i hoʻomohala ʻia ma ka papahana 6G-ADLANTIK ua hoʻokumu ʻia ma ka ʻenehana frequency comb, me nā alapine lawe ma luna o 500GHz.
Ma ke ala i ka 6G, he mea nui e hana i nā kumu hoʻoili terahertz e hāʻawi ana i kahi hōʻailona kiʻekiʻe a hiki ke uhi i ka laulā alapine ākea loa. ʻO ka hoʻohui ʻana i ka ʻenehana optical me ka ʻenehana uila kekahi o nā koho e hoʻokō ai i kēia pahuhopu i ka wā e hiki mai ana. Ma ka ʻaha kūkā EuMW 2024 ma Palisa, hōʻike ʻo R&S i kāna hāʻawi ʻana i ka noiʻi terahertz hou loa ma ka papahana 6G-ADLANTIK. Ke kālele nei ka papahana i ka hoʻomohala ʻana i nā ʻāpana alapine terahertz e pili ana i ka hoʻohui ʻana o nā photons a me nā electrons. Hiki ke hoʻohana ʻia kēia mau ʻāpana terahertz i hoʻomohala ʻia no nā ana hou a me ka hoʻoili ʻikepili wikiwiki. Hiki ke hoʻohana ʻia kēia mau ʻāpana ʻaʻole wale no ke kamaʻilio 6G, akā no ka ʻike ʻana a me ke kiʻi ʻana.
Ua kākoʻo ʻia ka papahana 6G-ADLANTIK e ke Kuhina Hoʻonaʻauao a me ka Noiʻi Pekelala Kelemania (BMBF) a ua hoʻonohonoho ʻia e R&S. ʻO nā hoa hana ʻo TOPTICA Photonics AG, Fraunhofer-Institut HHI, Microwave Photonics GmbH, Technical University of Berlin a me Spinner GmbH.
ʻO kahi ʻōnaehana terahertz tunable ultra-stable 6G e pili ana i ka ʻenehana photon
Hōʻike ka hōʻoia-o-ka-manaʻo i kahi ʻōnaehana terahertz paʻa loa, hiki ke hoʻololi ʻia no ka hoʻoili ʻikepili uea ʻole 6G e pili ana i nā mea hoʻohuihui terahertz photonic e hana ana i nā hōʻailona terahertz e pili ana i ka ʻenehana hui alapine (frequency comb). Ma kēia ʻōnaehana, hoʻololi maikaʻi ka photodiode i nā hōʻailona kuʻi optical i hana ʻia e nā lasers me nā alapine optical ʻokoʻa iki i nā hōʻailona uila ma o ke kaʻina hana o ka hui ʻana o ka photon. Hoʻololi ke ʻano antenna a puni ka mea hoʻohuihui photoelectric i ka photocurrent oscillating i nā nalu terahertz. Hiki ke hoʻololi ʻia a hoʻohemo ʻia ka hōʻailona hopena no ka kamaʻilio uea ʻole 6G a hiki ke hoʻololi maʻalahi ʻia ma kahi ākea ākea. Hiki ke hoʻonui ʻia ka ʻōnaehana i nā ana ʻāpana me ka hoʻohana ʻana i nā hōʻailona terahertz i loaʻa like. ʻO ka simulation a me ka hoʻolālā ʻana o nā ʻano waveguide terahertz a me ka hoʻomohala ʻana o nā oscillators reference photonic walaʻau haʻahaʻa loa kekahi o nā wahi hana o ka papahana.
ʻO ke kani haʻahaʻa loa o ka ʻōnaehana mahalo i ka frequency comb-locked optical frequency synthesizer (OFS) i loko o ka ʻenekini laser TOPTICA. ʻO nā mea hana kiʻekiʻe a R&S he ʻāpana koʻikoʻi o kēia ʻōnaehana: Hoʻokumu ka mea hana hōʻailona vector IF wideband R&S SFI100A i kahi hōʻailona baseband no ka modulator optical me ka helu laʻana o 16GS/s. Hoʻokumu ka mea hana hōʻailona RF a me ka microwave R&S SMA100B i kahi hōʻailona uaki kuhikuhi paʻa no nā ʻōnaehana TOPTICA OFS. Hoʻāʻo ka oscilloscope R&S RTP i ka hōʻailona baseband ma hope o ka mea hoʻokipa terahertz photoconductive continuous wave (cw) (Rx) ma ka helu laʻana o 40 GS/s no ka hana hou ʻana a me ka demodulation o ka hōʻailona alapine lawe 300 GHz.
6G a me nā koi o ke alapine alapine e hiki mai ana
E lawe mai ʻo 6G i nā hiʻohiʻona noi hou i ka ʻoihana, ka ʻenehana lapaʻau a me ke ola o kēlā me kēia lā. ʻO nā noi e like me metacomes a me Extended Reality (XR) e kau i nā koi hou ma ka latency a me nā helu hoʻoili ʻikepili i hiki ʻole ke hoʻokō ʻia e nā ʻōnaehana kamaʻilio o kēia manawa. ʻOiai ua ʻike ka International Telecommunication Union's World Radio Conference 2023 (WRC23) i nā hui hou ma ka spectrum FR3 (7.125-24 GHz) no ka noiʻi hou aku no nā pūnaewele 6G kalepa mua e hoʻokuʻu ʻia i ka makahiki 2030, Akā no ka hoʻomaopopo ʻana i ka hiki piha o ka virtual reality (VR), augmented reality (AR) a me nā noi mixed reality (MR), ʻo ka hui ʻo Asia-Pacific Hertz a hiki i ka 300 GHz e pono ai hoʻi.
