Izicelo Ezintsha zeIsixhobo sokubona iifoto esikhawulezayo
Ukukhanya, okukhazimlayo kangangokuba kuphantse kungabonakali, kodwa kumisela ukubetha konxibelelwano lwexesha elizayo… Kwihlabathi le-gigabit apho imiqondiso yokukhanya idlula kuyo yonke indawo, yonke imizuzwana yokulibaziseka inokuthetha ukulahleka kwedatha ebalulekileyo. Ukufunyanwa kwe-pulse yokukhanya okukhawulezayo, iinkqubo zonxibelelwano ze-43Gbit/s, ii-microwave photonic links… Ezi ndawo ziphambili zihlala zibuza: Ngaba kukho iskimu sokufumanisa i-optoelectronic esidibanisa uvakalelo oluphezulu kakhulu kunye nempendulo ekhawulezayo kakhulu?
Namhlanje, uthotho lwe-ROF-PT lokukhulisa ibhendi ngesantya esiphezuluisixhobo sokubona iifotoIimodyuli zinike impendulo ecacileyo neqinisekileyo.
Ngokudibanisa ngokunzulu isantya esiphezuluIzixhobo zokubona ii-PINNgeetships zokukhulisa zeTIA ezichanekileyo, senze ikhonkco elipheleleyo lokwenza ngcono isignali ukusuka ekungeneni ukuya ekuphumeni. Ukudibanisa ifayibha yemowudi enye kuqinisekisa ukufakwa kwesignali ecocekileyo, izihlanganisi ze-K zifumana imveliso ezinzileyo nesebenzayo, kwaye i-bandwidth ukuya kwi-40GHz kunye nexesha lokuphendula elingaphantsi kwe-10ps kwenza ukuba indlela yesignali ye-optical ingakwazi ukufihla. Nokuba kukubanjwa okubanzi koluhlu lwe-spectral lwe-1200-1650nm okanye ibhalansi ye-gain ephezulu, uvakalelo oluphezulu kunye ne-gain flatness, uthotho lwe-ROF-PT luhlala luzama ukufezekisa ibhalansi entle phakathi kwesantya kunye nokuchaneka.
Ijongene neemfuno ezingqongqo zenkqubo yokudibanisa ii-microwave ye-ROF okanye umngeni weempawu ezibuthathaka kwi-Brillouin sensing, inokuxhasa imveliso yokwahluka eyenzelwe wena, iyenze ikwazi ukudibana ngokulula noyilo lwenkqubo yakho ephezulu.
Ukwandiswa kwemitha yesantya esiphezulu yothotho lwe-ROF-PTisixhobo sokubona umbaneLe module inika iinjineli isisombululo esisebenzayo nesinokuthenjwa ngakumbi, esibenza bakwazi ukusingatha imisebenzi enzima yokubona imiqondiso yokukhanya ngoxolo olukhulu nokuzithemba. Le ayisiyo module nje kuphela; ikwasisiseko sokusebenza kwezicelo zobuchwepheshe be-optical zexesha elizayo - apha, indlela yokukhanya ibanjwa ngokuchanekileyo, kwaye isantya sichazwa sithi.
