Abaphandi kwiSikolo saseHarvard sobuNjineli kunye neeSayensi eziSetyenzisiweyo. UJohn A. Paulson (iHarvard John A. Paulson School of Engineering and Applied Sciences -SEAS) babe ngabokuqala kwihlabathi ukusebenzisa i-laser semiconductor ukwenza umjelo wonxibelelwano. Isixhobo esixutyiweyo se-electron-photonic sisebenzisa i-laser ukuvelisa kunye nokuhambisa imiqondiso ye-microwave kwaye ngenye imini inokukhokelela kuhlobo olutsha lonxibelelwano olungenazingcingo lwe-high-frequency.
Ukuphulaphula uDean Martin enze ingoma yakhe edumileyo ethi "Volare" evela kwisithethi sekhompyutheni kunokubonakala ngathi yinto eqhelekileyo ngokupheleleyo, kodwa xa usazi ukuba le yinkqubo yokuqala yosasazo lukanomathotholo usebenzisa iteknoloji yelaser, ngamava ahluke ngokupheleleyo. Isixhobo esitsha, esiphuhliswe liqela elivela kwi-SEAS, sisebenza sisebenzisa i-laser ye-infrared, yahlulwe yaba yimiqadi yeefrikhwensi ezahlukeneyo. Ukuba i-laser yesiqhelo ivelisa umqadi kwi-frequency enye, njengevayolin edlala inqaku elichanekileyo, ke isixhobo esenziwe zizazinzulu sikhupha imiqadi emininzi enezandi ezahlukeneyo, ezisasazwa ngokulinganayo kumlambo, njengamazinyo ekama yeenwele, enika igama lokuqala kwisixhobo - i-infrared laser-frequency comb (i-infrared laser frequency comb).
Ngo-2018, iqela le-SEAS lafumanisa ukuba "amazinyo" e-laser comb anokunxibelelana omnye nomnye, ebangela ukuba ii-electron kwi-laser cavity ukuba zijikeleze kwii-microwave frequencies kuluhlu lwerediyo. I-electrode ephezulu yesixhobo ine-slot etshisiweyo esebenza njenge-antenna ye-dipole kwaye isebenza njenge-transmitter. Ngokutshintsha iiparamitha ze-laser (ukuyimodareyitha), iqela liye lakwazi ukufaka ikhowudi yedatha yedijithali kwimitha ye-microwave. Umqondiso wawugqithiselwa kwindawo yokufumana, apho yathatyathwa yi-eriyali yesigodlo, yahluzwa kwaye yahlanjululwa yikhompyutheni.
"Esi sixhobo sidityanisiweyo sonke sinesithembiso esikhulu sonxibelelwano olungenazingcingo," utshilo uMarco Piccardo, isazinzulu sophando eSEAS. "Nangona iphupha lonxibelelwano olungenazingcingo lwe-terahertz lusekude, olu phando lusinika imephu yendlela ecacileyo ebonisa apho kufuneka siye khona."
Kwithiyori, i-laser transmitter enjalo ingasetyenziselwa ukuhambisa iimpawu kwii-frequencies ze-10-100 GHz kunye ne-1 THz, eya kuthi kwixesha elizayo ivumele ukuhanjiswa kwedatha ngesantya ukuya kwi-100 Gbit / s.
Uphando kwijenali yenzululwazi PNAS.
