Umshicileli werediyo we-laser wokuqala emhlabeni noma isinyathelo sokuqala esibheke ku-Wi-Fi ye-terahertz esheshayo

Abacwaningi baseHarvard School of Engineering and Applied Sciences. U-John A. Paulson (i-Harvard John A. Paulson School of Engineering and Applied Sciences - SEAS) babe ngabokuqala emhlabeni ukusebenzisa i-laser ye-semiconductor ukuze bakhe isiteshi sokuxhumana. I-hybrid electron-photonic device isebenzisa i-laser ukuze ikhiqize futhi idlulise amasignali e-microwave futhi ngelinye ilanga ingase iholele ohlotsheni olusha lokuxhumana okungenazintambo okunemvamisa ephezulu. 

Ukulalela uDean Martin enza ingoma yakhe edumile ethi "Volare" evela kusipika sekhompyutha kungase kubonakale njengento evamile, kodwa uma wazi ukuthi lokhu ukusakazwa komsakazo wokuqala kusetshenziswa ubuchwepheshe be-laser, kuyisipiliyoni esihluke ngokuphelele. Idivayisi entsha, eyakhiwe ithimba elivela kwaSEAS, isebenza kusetshenziswa i-infrared laser, ehlukaniswe yaba imishayo yamafrikhwensi ahlukene. Uma i-laser evamile ikhiqiza ugongolo ngemvamisa eyodwa, njengevayolini edlala inothi eliqondile, khona-ke umshini owenziwe ososayensi ukhipha imishayo eminingi enamaza ahlukene, asakazwa ngokulinganayo emfudlaneni, njengamazinyo ekama lezinwele, elinikeze. igama lokuqala kudivayisi - infrared laser-frequency comb (infrared laser frequency comb).

Ngo-2018, ithimba le-SEAS lathola ukuthi “amazinyo” ekama le-laser angakwazi ukuhambisana, okubangele ukuthi ama-electron asendaweni ye-laser anyakaze kumaza ama-microwave ebangeni lomsakazo. I-electrode ephezulu yedivayisi ine-slot emisiwe esebenza njenge-dipole antenna futhi isebenza njengesidlulisi. Ngokushintsha amapharamitha we-laser (ukuyimodela), ithimba likwazile ukufaka ikhodi yedatha emisebeni ye-microwave. Isignali yabe isidluliselwa endaweni yokwamukela, lapho yayithathwa khona uthi lwephondo, luhlungwe futhi lukhishwe ikhompuyutha.

"Le divayisi ehlanganisiwe yonke-in-one inesithembiso esihle sokuxhumana okungenantambo," kusho uMarco Piccardo, usosayensi wocwaningo kwaSEAS. "Yize iphupho lezokuxhumana okungenantambo kwe-terahertz lisekude, lolu cwaningo lusinika umhlahlandlela ocacile okhombisa lapho kufanele siye khona."

Ngokombono, isidluliseli se-laser singasetshenziswa ukudlulisa amasignali kumafrikhwensi angu-10–100 GHz futhi kufika ku-1 THz, okuzovumela ukudluliswa kwedatha ngesivinini esingafika ku-100 Gbit/s.

Ucwaningo yashicilelwa kujenali yesayensi i-PNAS.
