I-Revolutionizing Space Communication: I-Ultra-High Speed Optical Transmission.
Ososayensi nonjiniyela baye basungula ubuchwepheshe obusha obuthembisa ukuguqula izinhlelo zokuxhumana zasemkhathini. Lisebenzisa izithuthukisi ze-electro-optic intensity ezithuthukisiwe ze-850nm ezisekela i-10G, ukulahleka kokufakwa okuphansi, ugesi ophansi oyingxenye, nokuzinza okuphezulu, ithimba lithuthukise ngempumelelo i-sp...Funda kabanzi -
izixazululo zemoduli yokuqina okujwayelekile
I-intensity modulator Njengemoduli esetshenziswa kabanzi ezinhlelweni ezihlukene zokubona, ukuhlukahluka nokusebenza kwayo kungachazwa njengokuningi nokuyinkimbinkimbi. Namuhla, ngikulungiselele izixazululo ezine ezijwayelekile zamamoduli: izixazululo zemishini, izixazululo ze-electro-optical, i-Acousto-optic s...Funda kabanzi -
Umgomo kanye nenqubekela phambili yobuchwepheshe bezokuxhumana be-quantum
Ukuxhumana kwe-Quantum kuyingxenye emaphakathi ye-quantum information technology. Inezinzuzo zokufihla ngokuphelele, umthamo omkhulu wokuxhumana, isivinini sokudlulisa ngokushesha, nokunye. Ingakwazi ukuqedela imisebenzi ethile ukuxhumana kwakudala okungakwazi ukuyifinyelela. Ukuxhumana kweQuantum kungasisiza...Funda kabanzi -
Isimiso nokuhlukaniswa kwenkungu
Isimiso nokuhlukaniswa kwenkungu (1)isimiso Umgomo wenkungu ubizwa ngokuthi umphumela we-Sagnac ku-physics. Endleleni yokukhanya evaliwe, amalambu amabili okukhanya avela emthonjeni ofanayo wokukhanya azophazanyiswa lapho ehlanganiswa endaweni efanayo yokutholwa. Uma indlela yokukhanya evaliwe ine-rotation relati...Funda kabanzi -
Umgomo wokusebenza we-coupleal eqondisayo
Ama-coupler aqondisayo ayizingxenye ezijwayelekile zamagagasi e-microwave/millimeter esikalini se-microwave namanye amasistimu ama-microwave. Angasetshenziselwa ukuhlukanisa isignali, ukuhlukanisa, nokuxuba, njengokuqapha amandla, ukuqiniswa kwamandla okukhipha umthombo, ukuhlukaniswa komthombo wesignali, ukudlulisa kanye ne-refl...Funda kabanzi -
Yini i-EDFA Amplifier
I-EDFA (Erbium-doped Fiber Amplifier), eyasungulwa okokuqala ngo-1987 ukuze isetshenziselwe ukuhweba, iyisikhulisamazwi esisetshenziswa kakhulu sohlelo lwe-DWDM esebenzisa i-Erbium-doped fiber njengendlela yokukhulisa i-optical ukuze kuthuthukiswe amasignali ngokuqondile. Inika amandla ukukhuliswa okusheshayo kwamasignali ane-mul...Funda kabanzi -
Imoduli Yesigaba Sokukhanya Esincane Esibonakalayo Esinamandla Aphansi Kunawo Wonke Iyazalwa
Eminyakeni yamuva nje, abacwaningi abavela emazweni ahlukahlukene basebenzise ama-photonics ahlanganisiwe ukuze babone ngokulandelana ukukhohliswa kwamaza okukhanya kwe-infrared futhi bawasebenzise kumanethiwekhi anesivinini esiphezulu se-5G, izinzwa zama-chip, nezimoto ezizimele. Njengamanje, ngokujula okuqhubekayo kwalesi siqondiso socwaningo...Funda kabanzi -
42.7 Gbit/S Electro-Optic Modulator kuSilicon Technology
Enye yezinto ezibaluleke kakhulu zemoduli ye-optical isivinini sayo sokushintshashintsha noma umkhawulokudonsa, okufanele okungenani usheshe njengezinto zikagesi ezitholakalayo. Ama-Transistors anamaza okuthutha angaphezu kuka-100 GHz asebonisiwe kubuchwepheshe be-silicon ye-90 nm, futhi ijubane lizo ...Funda kabanzi
