I-Rare Earths “Ikhanyisa” Ikusasa Lokuxhumana Okubonakalayo! Ukuthola Izici Zomlingo Ezingemuva Kwezokuxhumana Kwanamuhla

Esikhathini se-5G ngisho ne-6G, lapho amavidiyo anencazelo ephezulu edluliselwa khona ngemizuzwana futhi idatha enkulu ishintshaniswa khona manjalo, “amandla ayimfihlakalo” acasha ngemuva kwezigcawu—izinhlanganisela zomhlaba ezingavamile. Njengoba zibonakala ziphansi, zidlala indima engenakuphikwa ekuxhumaneni nge-optical fiber.

Ukuxhumana nge-optical fiber kufana “nomgwaqo omkhulu wolwazi,” futhi ama-rare earth compounds “angonjiniyela abakhulu” kulo mgwaqo omkhulu. Okokuqala, ama-rare earth-doped optical fibers akhulisa kakhulu ukusebenza kahle kokudlulisa. Ngokwandisa inkomba yokukhanya kwenhliziyo, athuthukisa ukudluliselwa kokukhanya, avumela idatha ukuthi idlule kuma-fibers “ngesivinini sokukhanya” njengesitimela esisheshayo, okuthuthukisa kakhulu ukusebenza kahle kokudlulisa.

Ukudluliselwa kwebanga elide bekulokhu kubhekene nenkinga enzima yokuncipha kwesignali kanye nokuphambuka. Ama-Rare earth compounds axazulula lokhu ngempumelelo ngokunciphisa imiphumela engeyona eqondile kumafayibha—njengokufaka “isiqinisi” sesignali. Lokhu kunciphisa ukuphambuka kanye nokuphambuka, kuqinisekisa ukudluliselwa okuzinzile futhi kuthuthukisa kakhulu ukuthembeka kohlelo.

Izimo ezahlukene zokuxhumana zidinga ubude be-wavelength obuhlukahlukene. Ngezakhiwo zazo ezihlukile, ama-compounds e-rare earth avumela ukulungiswa okuguquguqukayo kwama-wavelength ngokulungisa amazinga e-doping. Lokhu kuvumela ukuxhumana kwe-optical fiber ukuthi kuvumelane nezinhlelo zokusebenza ezahlukahlukene, kusukela ku-telemedicine kanye nokusakaza bukhoma kwe-HD kuya ekudlulisweni kwedatha ye-smart grid.

 Ngesikhathi sokudluliselwa kwesignali ebangeni elide, imicu engavamile efakwe emhlabeni nayo isebenza “njengeziteshi zikaphethiloli zesignali.” Ngokwanda okuphezulu kanye nomkhawulokudonsa omkhulu wokwanda, ikhulisa izimpawu zokukhanya ezibuthakathaka, yandisa ibanga lokudlulisela futhi ithuthukise ikhwalithi—njengokuvuselela isignali ekhathele ibe amandla aphelele.

 Ngaphezu kwalokho, imicu efakwe i-cerium isebenza indima ekhethekile njengemidiya ye-laser ezinhlelweni zokuxhumana ze-optical, ihlinzeka ngemithombo yokukhanya ezinzile yama-laser.

 Kusukela ekuthuthukiseni ukusebenza kahle kokudlulisa kuya ekuzinziseni izimpawu, ukulungisa amaza obubanzi ngendlela eguquguqukayo, ukukhulisa izimpawu, kanye nokusebenza njenge-laser media, ama-rare earth compounds enza ngcono ukusebenza kokuxhumana nge-optical fiber. Aqinisa ukuzinza kohlelo kanye nokuguquguquka, abeka isisekelo esiqinile sokwakha amanethiwekhi okuxhumana e-optical anamuhla asheshayo, anamandla amakhulu. Njengoba ubuchwepheshe buthuthuka, ama-rare earths alungele ukudlala indima enkulu nakakhulu ekuxhumaneni kwe-optical, aletha okuhlangenwe nakho kokuxhumana okusheshayo nokuzinzile futhi aqhubekisele phambili intuthuko esheshayo yesikhathi sedijithali.
