Mtundu wodziwika bwino wa amplifier ya kuwala yomwe imagwiritsidwa ntchito polankhulana ndi kuwala

Mtundu wamba wachokulitsa kuwalaamagwiritsidwa ntchito polankhulana ndi kuwala

Pamene zizindikiro za kuwala zimatumizidwa mu ulusi wa kuwala, pamene mtunda ukuwonjezeka, zizindikiro za kuwala zimafooka pang'onopang'ono ndipo zimayambitsa kusokonezeka kwa kulumikizana… Mpaka kuwonekera kwa ma amplifiers a kuwala, amakhala ngati "malo opangira mafuta", akudzaza mphamvu za zizindikiro za kuwala kuti athe kunyamula deta mosavuta kupita komwe akupita. Nkhaniyi ikukupatsani amplifier yodziwika bwino yolumikizirana ndi kuwala -chokulitsa cha ulusi chopangidwa ndi erbium(EDFA optical amplifier).

Chojambulira cha ulusi chopangidwa ndi erbium, monga momwe dzinalo likusonyezera: Erbium (Er), chinthu chosowa chapadziko lapansi, chimaphatikizidwa mu ulusi wa quartz. Pamene chizindikiro cholowera cha kuwala chikudutsa mu ulusi wopangidwa ndi erbium, ma ion a erbium atatu (Er³⁺) adzayamwa mphamvu ya kuwala kwa pampu ndikusintha kupita ku mphamvu yapamwamba. Chiwerengero cha tinthu tating'onoting'ono mu mkhalidwe wosangalatsidwa chimadutsa mu inversion. Pansi pa induction ya kuwala kwa chizindikiro cholowera, ma ion a rare earth osangalatsidwa-state amadutsa mu emission yolimbikitsidwa ndikutulutsa ma photon afupipafupi ofanana ndi kuwala kwa chizindikiro, motero amapeza optical amplification.
Zigawo zomwe zimapangaEDFA chokulitsa kuwalaKawirikawiri zimaphatikizapo ma optical couplers (nthawi zambiri amagwiritsa ntchito ma wavelength division multiplexers WDM), ma optical isolators, ulusi wopangidwa ndi erbium, zosefera, ndi magwero a pampu. Pakati pawo, optical coupler imaphatikiza mwanzeru kuwala kolowera ndi kuwala kwa pampu kuti zitsimikizire kuti chizindikirocho chalowetsedwa molondola mu ulusi wopangidwa ndi erbium; ntchito ya optical isolator ndikuletsa kuwala kopanda ntchito munjira yowunikira kuti zizindikiro zosafunikira zisapangidwe, kuonetsetsa kuti chizindikirocho chikufalikira mbali imodzi; optical fyuluta imachotsa phokoso losafunikira kuti ikonze chiŵerengero cha chizindikiro-ku-phokoso ndikuwonetsetsa kuti chidziwitso chikufalikira bwino.
Pakadali pano, ofufuza akupanga ma amplifiers a ulusi wa dual-band (DBFA) ndi ma amplifiers a ultra-wideband (UWOA), cholinga chawo ndi kukulitsa bandwidth ya gain ku band yonse ya wavelength division multiplexing (WDM) frequency band. Posachedwapa, gulu lofufuza logwirizana kuchokera ku mabungwe ofufuza aku Europe lapanga amplifier yoyendera mafunde parametric kutengera ma photonic chips. Kudzera mu kapangidwe kakang'ono, imakwaniritsa kukulitsa kwa chizindikiro cha ultra-wideband, yokhala ndi bandwidth ya 140 nm (kuwirikiza katatu kuposa EDFA yachikhalidwe), ndipo voliyumu yachepetsedwa kufika pamlingo wa sentimita, kupereka chithandizo cha liwiro lapamwamba kwambiri ku malo osungira deta ndi AI computing. "Ma amplifiers apamwamba" awa azithandizira kutumiza ma wavelengths opitilira zana pa ulusi uliwonse, ndikuyika maziko a kulumikizana kwa holographic ndi mafakitale anzeru ndi ntchito zina munthawi ya 6G.
