Vatsvagiri paHarvard Chikoro cheUinjiniya neApplied Sayenzi. John A. Paulson (Harvard John A. Paulson School of Engineering and Applied Sciences - SEAS) ndivo vakatanga munyika kushandisa semiconductor laser kugadzira nzira yekukurukurirana. Iyo hybrid electron-photonic mudziyo inoshandisa laser kugadzira uye kufambisa masaini emicrowave uye rimwe zuva inogona kutungamira kune imwe mhando yemhando yepamusoro-frequency isina waya yekutaurirana.
Kuteerera Dean Martin achiita rwiyo rwake rwakakurumbira "Volare" kubva kumutauri wekombuta zvingaite sechinhu chakajairika, asi kana iwe uchiziva kuti iyi ndiyo yekutanga kutepfenyura redhiyo uchishandisa laser tekinoroji, chiitiko chakasiyana zvachose. Chishandiso chitsva, chakagadziridzwa nechikwata kubva kuSEAS, chinoshanda chichishandisa infrared laser, yakakamurwa kuita matanda emhando dzakasiyana. Kana iyo yakajairika laser inogadzira danda pane imwe frequency, seviolin inoridza chaiyo noti, ipapo mudziyo wakagadzirwa nesainzi unoburitsa matanda mazhinji ane ma frequency akasiyana, ayo akagoverwa zvakaenzana murukova, semazino emuzinga webvudzi, uyo akapa. zita rekutanga kune mudziyo - infrared laser-frequency comb (infrared laser frequency comb).
Muna 2018, timu yeSEAS yakaona kuti "mazino" emuzinga welaser anogona kuwirirana, zvichikonzera kuti maerekitironi ari mugomba relaser atenderere pama microwave frequencies muredhiyo. Iyo yepamusoro electrode yechishandiso ine etched slot iyo inoshanda seantenna dipole uye inoita seyekuparadzira. Nekuchinja ma parameter eiyo laser (modulating it), timu yakakwanisa kukodha data yedhijitari mune microwave radiation. Chiratidzo chakabva chaendeswa kunzvimbo yekugamuchira, kwainotorwa nenyanga antenna, yakasefa uye yakadhindwa nekombuta.
"Chishandiso ichi chakabatanidzwa chese-mu-chimwe chine vimbiso huru yekutaurirana pasina waya," anodaro Marco Piccardo, musayendisiti wekutsvagisa kuSEAS. "Kunyangwe kurota kwe terahertz wireless communications kuchiri kure, tsvagiridzo iyi inotipa gwara rakajeka rinoratidza kwatinofanira kuenda."
Muchiono, yakadai selaser transmitter inogona kushandiswa kufambisa masaini pamafrequency e10-100 GHz uye anosvika 1 THz, iyo mune ramangwana ichabvumira kufambiswa kwedata nekumhanya kunosvika ku100 Gbit/s.
