Ofufuza ku Harvard School of Engineering ndi Applied Sciences. John A. Paulson (Harvard John A. Paulson School of Engineering and Applied Sciences - SEAS) anali oyamba padziko lapansi kugwiritsa ntchito laser semiconductor kuti apange njira yolumikizirana. Chipangizo cha hybrid electron-photonic chimagwiritsa ntchito laser kupanga ndi kutumiza ma siginecha a ma microwave ndipo tsiku lina zitha kubweretsa mtundu watsopano wamalumikizidwe opanda zingwe opanda zingwe.
Kumvetsera kwa Dean Martin kuchita nyimbo zake zodziwika bwino "Volare" kuchokera kwa wokamba nkhani pakompyuta zingawoneke ngati chinthu wamba, koma mutadziwa kuti iyi ndi wailesi yoyamba kugwiritsa ntchito luso la laser, ndizosiyana kwambiri. Chipangizo chatsopanocho, chopangidwa ndi gulu lochokera ku SEAS, chimagwira ntchito pogwiritsa ntchito laser infrared, yogawidwa m'miyendo ya ma frequency osiyanasiyana. Ngati laser wamba imapanga mtengo pama frequency amodzi, ngati violin ikusewera mawu enieni, ndiye kuti chipangizocho chopangidwa ndi asayansi chimatulutsa matabwa ambiri okhala ndi ma frequency osiyanasiyana, omwe amagawidwa mofanana mumtsinje, ngati mano a chisa cha tsitsi. dzina loyambirira ku chipangizocho - chisa cha infrared laser-frequency (infrared laser frequency chisa).
Mu 2018, gulu la SEAS lidazindikira kuti "mano" a chisa cha laser amatha kulumikizana wina ndi mnzake, zomwe zimapangitsa kuti ma elekitironi omwe ali mumphuno ya laser aziyenda pamayendedwe a microwave pamawayilesi. Elekitirodi yapamwamba ya chipangizocho imakhala ndi kagawo kakang'ono komwe kamakhala ngati mlongoti wa dipole ndikuchita ngati chotumizira. Mwa kusintha magawo a laser (modulating it), gululo lidatha kuyika deta ya digito mu radiation ya microwave. Chizindikirocho chinatumizidwa kumalo olandirirako, kumene chinatengedwa ndi mlongoti wa nyanga, ndikusefedwa ndi kusindikizidwa ndi kompyuta.
"Chida chophatikizika ichi chili ndi lonjezo lalikulu la kulumikizana opanda zingwe," akutero Marco Piccardo, wasayansi wofufuza ku SEAS. "Ngakhale maloto a terahertz olumikizana opanda zingwe akadali kutali, kafukufukuyu amatipatsa chithunzi chowonekera bwino chomwe tikuyenera kupita."
Mwachidziwitso, cholumikizira cha laser choterechi chingagwiritsidwe ntchito kutumiza ma siginecha pafupipafupi 10-100 GHz mpaka 1 THz, zomwe m'tsogolomu zidzalola kutumiza kwa data pa liwiro la 100 Gbit / s.
