I-Intelligent Intelligent Terahertz Electro-Optic Modulator ithuthukiswe ngempumelelo

Ngonyaka owedlule, iqembu likaSheng Zhigao, umcwaningi esikhungweni sezinsikazi esiphakeme seStefei Institute of the Hefei Institute of the Hefei Institute of Work Science, Chinese Academy of Sciences Sciences, Chinese Academy of Electroinces, athuthukise i-Teraher-Electro-Optic Modulator ethembela kudivayisi yokuhlola yamandla kamazibuthe eqinile. Ucwaningo lushicilelwa kwizinto ezisetshenziswayo ze-ACS nezindawo zokuxhumana.

Yize ubuchwepheshe be-terahertz bunezici eziphakeme zokubukeka kanye namathemba abanzi wohlelo lokusebenza, uhlelo lwayo lobunjiniyela lusalinganiselwe kakhulu ukuthuthukiswa kwezinto zeTerahertz nezakhi zeTerahertz. Phakathi kwazo, ukulawula okusebenzayo nokuqondayo kwama-terahertz wave ngensimu yangaphandle kuyindlela ebalulekile yocwaningo kule nkambu.

Ukuhlose ukuqondiswa kokucwaninga okunqenqemeni kwezakhi eziyisisekelo zeTerahertz, iqembu lokucwaninga lisungule i-Teraherttz Dissedu Modulator esuselwa ku-graphene enezici ezimbili. Optical mater. I-6, 1700877 (2018)], i-Terahertz Broadband PhotoControlled Modulator esekelwe kwi-oxis applide ehambisana kakhulu ne-ACS. Mater. Inter. 12, ngemuva kuka-48811 (2020)] no-2020)] umthombo osuselwa kubuthe be-terarfy obusezingeni eliphansi le-shor Ukushintshwa okusebenzayo okusebenzayo kokudluliselwa kweTerahertz, ukuboniswa kanye nokumunca kutholakala (isithombe a). Imiphumela ikhombisa ukuthi ngaphezu kokudluliselwa kanye nokuvumayo, isigaba sokubonisa nokumbozwa futhi singalawulwa ngenkuthalo yindawo kagesi, lapho ukujula kwamandla kagesi kungafinyelela ku-99.9% (isithombe b). Kuyathakazelisa kakhulu ukufezekisa ukulawulwa kukagesi kweTerrahertz, abacwaningi baklama idivaysi eneqhawe "Terahertz - Electric-Tepharetz" Impendulo Loop (Umfanekiso c). Kungakhathalekile ukuthi ushintsho ezimweni zokuqalisa kanye nemvelo yangaphandle, idivaysi ehlakaniphile ingafinyelela ngokuzenzakalelayo isethi (elindelekile) ye-Terahertz yokushintshana ngenani ngemizuzwana engama-30.

Ukuthuthukiswa kwe-terartz esebenzayo nenobuhlakaniI-Electro-Optic ModulatorNgokuya ngezinto ezisetshenziswayo ze-elekthronikhi ezihambisanayo zihlinzeka ngombono omusha wokugcwaliseka kweTerahertz control control. Lo msebenzi wasekelwa nguNational Key Research and Development Programme, iNational Natural Science Foundation kanye nesiKhwama esiphezulu se-Magnetic Forund Laboratory Rection esifundazweni sase-Anhui.
