Kapangidwe ka zipangizo zolumikizirana ndi kuwala

Kapangidwe kazipangizo zolumikizirana ndi kuwala

Dongosolo lolumikizirana lomwe lili ndi mafunde owala ngati chizindikiro ndi ulusi wowala ngati njira yotumizira mauthenga limatchedwa dongosolo lolumikizirana la ulusi wowala. Ubwino wa kulumikizana kwa ulusi wowala poyerekeza ndi kulumikizana kwachikhalidwe kwa chingwe ndi kulumikizana kwa opanda zingwe ndi awa: mphamvu yayikulu yolumikizirana, kutayika kochepa kwa kutumiza mauthenga, mphamvu yayikulu yotsutsana ndi maginito, chinsinsi champhamvu, komanso zinthu zopangira ulusi wowala ndi silicon dioxide yokhala ndi malo ambiri osungira. Kuphatikiza apo, ulusi wowala uli ndi ubwino wa kukula kochepa, kulemera kopepuka komanso mtengo wotsika poyerekeza ndi chingwe.
Chithunzi chotsatirachi chikuwonetsa zigawo za dera losavuta lolumikizidwa ndi photonic:laser, kugwiritsanso ntchito kwa kuwala ndi chipangizo chochotsera zinthu zambirimbiri,chowunikira zithunzindimodulator.

Kapangidwe koyambira ka njira yolumikizirana ya ulusi wa kuwala kumaphatikizapo: chotumizira chamagetsi, chotumizira chamagetsi, ulusi wotumizira, cholandirira chamagetsi ndi cholandirira chamagetsi.
Chizindikiro chamagetsi chothamanga kwambiri chimalembedwa ndi chotumizira chamagetsi kupita ku chotumizira chamagetsi, kenako chimasanduka zizindikiro zamagetsi pogwiritsa ntchito zipangizo zamagetsi monga chipangizo cha Laser (LD), kenako chimalumikizidwa ku ulusi wotumizira.
Pambuyo potumiza chizindikiro cha kuwala mtunda wautali kudzera mu ulusi wa single-mode, amplifier ya ulusi wopangidwa ndi erbium ingagwiritsidwe ntchito kukulitsa chizindikiro cha kuwala ndikupitiliza kutumiza. Pambuyo polandira kuwala, chizindikiro cha kuwala chimasinthidwa kukhala chizindikiro chamagetsi ndi PD ndi zida zina, ndipo chizindikirocho chimalandiridwa ndi wolandila magetsi kudzera mu kukonza magetsi pambuyo pake. Njira yotumizira ndi kulandira zizindikiro kumbali ina ndi yomweyo.
Pofuna kukwaniritsa muyezo wa zida zomwe zili mu ulalo, chotumizira kuwala ndi cholandirira kuwala chomwe chili pamalo omwewo zimaphatikizidwa pang'onopang'ono kukhala Transceiver yowala.
Liwiro lapamwambaGawo lotumizira kuwalaimapangidwa ndi Receiver Optical Subassembly (ROSA; Transmitter Optical Subassembly (TOSA) yomwe imayimiridwa ndi zida zowunikira zogwira ntchito, zida zosagwira ntchito, ma functional circuits ndi zida zolumikizirana ndi photoelectric zimayikidwa. ROSA ndi TOSA zimayikidwa ndi ma laser, ma photodetector, ndi zina zotero mu mawonekedwe a ma optical chips.

Poyang'anizana ndi zovuta zakuthupi ndi zaukadaulo zomwe zakumana nazo pakukula kwa ukadaulo wa ma microelectronics, anthu anayamba kugwiritsa ntchito ma photon ngati zonyamulira chidziwitso kuti akwaniritse bandwidth yayikulu, liwiro lalikulu, kugwiritsa ntchito mphamvu zochepa, komanso kuchepetsa kuchedwa kwa photonic inteated circuit (PIC). Cholinga chofunikira cha photonic integrated loop ndikukwaniritsa kuphatikiza kwa ntchito zopangira kuwala, kulumikizana, kusintha, kusefa, kutumiza, kuzindikira ndi zina zotero. Mphamvu yoyamba yoyendetsera ma photonic integrated circuits imachokera ku kulumikizana kwa deta, kenako yakula kwambiri mu ma microwave photonics, quantum information processing, nonlinear optics, masensa, lidar ndi madera ena.
