Iindaba zamva nje zophando lweilaser yonxibelelwano lwesithuba
Inkqubo ye-intanethi yesathelayithi, egubungela ihlabathi liphela, i-latency ephantsi kunye ne-bandwidth ephezulu, iye yaba yindlela ephambili yophuhliso lwetekhnoloji yonxibelelwano kwixesha elizayo. Unxibelelwano lwe-laser yesithuba lubuchwepheshe obuphambili ekuphuhlisweni kwenkqubo yonxibelelwano lwesathelayithi.Ileyiza ye-semiconductoribonisa amandla amaninzi okusetyenziswa kwinkqubo yonxibelelwano lwelasi yesithuba ngenxa yokusebenza kwayo okuphezulu, ubomi obude, ubungakanani obuncinci, ubunzima obulula kunye neempawu ezibalaseleyo zokuguquguquka. Nangona kunjalo, imisebe yelanga ye-cosmic, imisebe ye-galactic cosmic kunye nenani elikhulu lamasuntswana atshajiweyo anamandla aphezulu afana neeproton, ii-electron kunye nee-ion ezinzima kwibhanti yokubamba i-geomagnetic kwindawo yesithuba zinokukhokelela ekonakaleni kokusebenza kwesixhobo kwaye zikhokelele ekungasebenzini kwesixhobo, okusongela kakhulu ukuthembeka kunye nokuzinza kweenkqubo zonxibelelwano lwelasi yesithuba.
UMZOBO 1. Isixhobo sovavanyo seilezauvavanyo lokusebenza
Kutshanje, iqela lophando eTshayina lenze inkqubela phambili ebalulekileyo kuphando lokusebenza kwee-laser ze-quantum dot kwibhendi yonxibelelwano lwesithuba. Ngokusebenzisa uyilo olutsha lwebhendi kunye nokwenza ngcono ulwakhiwo lwengingqi esebenzayo, iqela liphuhlise ngempumelelo iziphumo zophando zamva nje zee-laser zonxibelelwano lwesithuba, ezisebenza kakuhle kakhulu kwindawo enamasuntswana anamandla aphezulu, ii-laser ze-quantum dot. Baqhube uhlalutyo olunzulu lokuthelekisa ukusebenza kweenkqubo ezahlukeneyo zezinto kwindawo enamasuntswana. Iziphumo zovavanyo zibonisa ukuba isakhiwo se-quantum dot sibonisa iingenelo ezimangalisayo zokuzinza kwesakhiwo kwindawo enamasuntswana anamandla aphezulu kwi-orbit ephantsi yoMhlaba.
Ngokusekelwe kolu phando, iqela lophando liyile ngempumelelo kwaye lenza uhlobo olutsha lwei-laser ye-quantum dot. Esi sixhobo sibonisa ukusebenza okugqwesileyo kwiindawo ezigqithisileyo: kwi-3MeV proton injection ukuya kuthi ga kwi-7×1013 cm-2, i-laser igcina i-linewidth enhancement factor esondele kwi-zero; Ingxolo ephakathi yoxinzelelo (RIN) yesixhobo iphantsi njenge--163 dB/Hz, nokuba kumthamo ophezulu we-injection, i-RIN iyanda nge-1 dB/Hz kuphela. Ukongeza, i-laser isakwazi ukusebenza ngokuzinzileyo phantsi kwemeko yokukhanya enamandla ye--3.1dB. Le mpumelelo ayiqinisekisi kuphela iziphumo zophando zamva nje zee-laser zonxibelelwano lwesithuba, kodwa ikwabonelela nge-reliableisisombululo somthombo wokukhanyaukwakhiwa kweenethiwekhi zonxibelelwano zesathelayithi ezisebenzayo kakhulu.
