Cilmi-baarayaasha Harvard School of Engineering and Applied Sciences. John A. Paulson (Harvard John A. Paulson School of Engineering and Applied Sciences - SEAS) ayaa ahaa kuwii ugu horeeyay aduunka ee isticmaala leysarka semiconductor si loo abuuro kanaal isgaarsiineed. Qalabka elektaroonigga ah ee isku-dhafka ah wuxuu isticmaalaa laser si uu u soo saaro oo u gudbiyo calaamadaha microwave wuxuuna maalin u horseedi karaa nooc cusub oo isgaarsiin wireless ah oo sarreeya.
Dhegeysiga Dean Martin wuxuu sameeyaa halabuurkiisa caanka ah "Volare" ee ku hadla kombuyuutarku wuxuu u ekaan karaa wax caadi ah, laakiin markaad ogaato in tani ay tahay baahinta raadiyaha ugu horreeya iyadoo la adeegsanayo tignoolajiyada laysarka, waa khibrad gebi ahaanba ka duwan. Qalabkan cusub, oo ay soo saareen koox ka socota SEAS, ayaa ku shaqeysa laysarka infrared, oo u qaybsan alwaaxyo kala duwan. Haddii laser-ga caadiga ah uu soo saaro bim hal mar ah, sida violin oo ciyaaraya qoraal sax ah, markaa qalabka ay sameeyeen saynisyahannadu waxay soo saaraan alwaaxyo badan oo kala duwan, kuwaas oo si siman loogu qaybiyo qulqulka, sida ilkaha shanlada timaha, taas oo bixisay Magaca asalka ah ee aaladda - shanlada laser-ka-soo-celinta infrared (shanlada inta jeer ee leysarka infrared).
2018, kooxda SEAS waxay ogaadeen in "ilkaha" ee shanlada laysarka ay isku soo celin karaan midba midka kale, taasoo keentay electrons ee godka laysarka si ay u wareegaan mikrowaytka raadiyaha. Electrode-ka ugu sarreeya ee aaladda waxa uu leeyahay dalool xardhan oo u shaqeeya sidii anteeno dipole oo u dhaqma sidii gudbiye. Beddelidda cabbirrada laysarka (isbedelka), kooxdu waxay awooday inay ku qorto xogta dhijitaalka ah shucaaca microwave-ka. Dabeeto signalka waxa loo sii gudbiyay meesha laga soo gaadhayo,halkaas oo laga soo qaaday anteeno gees ah,kadibna lagu shaandheeyay oo kombuyuutarku sifeeyay.
"Qalabkan isku-dhafan oo dhan-hal-hal ah ayaa ballan-qaad weyn u ah isgaarsiinta wireless-ka," ayuu yiri Marco Piccardo, saynisyahanka cilmi-baarista ee SEAS. "In kasta oo riyada isgaarsiinta wireless-ka ee terahertz ay weli fog tahay, cilmi-baaristan waxay na siinaysaa khariidad cad oo muujinaysa halka aan u baahanahay inaan aadno."
Aragti ahaan, gudbiyaha laysarka noocan oo kale ah ayaa loo isticmaali karaa in lagu gudbiyo calaamadaha isdaba jooga 10-100 GHz iyo ilaa 1 THz, taas oo mustaqbalka u oggolaan doonta gudbinta xogta xawaare dhan 100 Gbit/s.
