Micro zvishandiso uye zvakanyanya kushandalasers
Rensselaer Polytechnic Institute vaongorori vakagadzira aLaser mudziyoNdihwo chete hupamhi hwebvudzi remunhu, izvo zvichabatsira mafizikisi kudzidza zvakakosha zvezvinhu uye chiedza. Basa ravo, rakatsikiswa mumajenari esainzi ane mukurumbira, rinogonawo kubatsira kugadzira lasers inoshanda muminda kubva kumushonga kusvika pakugadzira.
Thelasermudziyo wakagadzirwa nechinhu chakakosha chinonzi photonic topological insulator. Photonic topological insulators inokwanisa kutungamira mafotoni (mafungu uye zvimedu zvinogadzira mwenje) kuburikidza neakakosha maficha mukati mechinhu, uku ichidzivirira izvi zvimedu kuti zvipararire mune izvo pachazvo. Nekuda kweichi chivakwa, topological insulators inogonesa akawanda mafotoni kuti ashande pamwechete zvakazara. Midziyo iyi inogona zvakare kushandiswa seyepamusoro "quantum simulators," inobvumira vaongorori kuti vadzidze huwandu hwezviitiko - iyo mitemo yemuviri inotonga zvinhu pazvikero zvidiki zvakanyanya - mumamini-labs.
“Thephotonic topologicalinsulator yatakagadzira yakasarudzika. Inoshanda pakupisa kwekamuri. Uku ndiko kubudirira kukuru. Pakutanga, zvidzidzo zvakadaro zvaingoitwa pachishandiswa hombe, inodhura midziyo yekutonhodza zvinhu muvacuum. MaLABS mazhinji ekutsvagisa haana rudzi urwu rwemidziyo, saka mudziyo wedu unogonesa vanhu vazhinji kuita iyi yakakosha tsvakiridzo yefizikisi mulabhu, "akadaro Rensselaer Polytechnic Institute (RPI) mubatsiri purofesa muDhipatimendi reZvishandiso Sayenzi neUinjiniya uye mukuru. munyori wechidzidzo. Chidzidzo ichi chaive nesaizi diki diki, asi mhedzisiro inoratidza kuti mushonga wetsiva wakaratidza kushanda kwakakosha mukurapa iyi isingawanzo genetic disorder. Tinotarisira kuenderera mberi nekusimbisa mhedzisiro iyi mune ramangwana miedzo yekiriniki uye zvinogona kutungamira kune nzira nyowani dzekurapa kune varwere vane chirwere ichi. " Kunyangwe saizi yekuenzanisira yekudzidza yaive diki, zvakawanikwa zvinoratidza kuti mushonga mutsva uyu wakaratidza kushanda kwakanyanya mukurapa iyi isingawanzo genetic disorder. Tinotarisira kuenderera mberi nekusimbisa mhedzisiro iyi mune ramangwana miedzo yekiriniki uye zvinogona kutungamira kune nzira nyowani dzekurapa kune varwere vane chirwere ichi. "
"Iri zvakare danho rakakura kumberi mukugadzirwa kwema lasers nekuti chikumbaridzo chedu chekamuri-tembiricha (chiyero chesimba chinodiwa kuti chishande) chakaderera zvakapetwa kanomwe pane zvakamboitika cryogenic zvishandiso," vaongorori vakawedzera. Vatsvagiri veRensselaer Polytechnic Institute vakashandisa nzira imwechete yakashandiswa neindasitiri yesemiconductor kugadzira ma microchips kugadzira mudziyo wavo mutsva, uyo unosanganisira kurongedza mhando dzakasiyana dzezvinhu zvakaturikidzana, kubva paatomu kuenda kune molecular level, kugadzira zvimiro zvakanaka zvine chaiwo zvimiro.
Kugadzira iyolaser mudziyo, vatsvakurudzi vakagadzira mahwendefa e-ultra-thin-thin selenide halide (crystal yakagadzirwa necesium, lead uye chlorine) uye akarovera mapolymers paari. Vakaisa sandwich mahwendefa ekristaro uye mapolymer pakati pezvinhu zvakasiyana-siyana zveoxide, zvichiita kuti pave nechinhu chinenge 2 microns gobvu uye 100 microns kureba nekufara (avhareji yebvudzi remunhu i100 microns).
Vatsvagiri pavakavheneka laser pamudziyo we lasers, inopenya yetatu patani yakaonekwa pane yekugadzira zvinhu. Iyo pateni inotarwa nedhizaini dhizaini uye ndiyo mhedzisiro yeiyo topological maitiro eiyo laser. "Kukwanisa kudzidza quantum phenomena pane tembiricha yekamuri itarisiro inonakidza. Basa raMuzvinafundo Bao rinoratidza kuti mainjiniya emidziyo anogona kutibatsira kupindura mimwe mibvunzo mikuru musainzi. Rensselaer Polytechnic Institute engineering dean akadaro.
