Midziyo midiki uye inoshanda zvakanyanyalasers
Vaongorori veRensselaer Polytechnic Institute vakagadzira chirongwa chemudziyo welaserIhwohwo hupfupi hwebvudzi remunhu, izvo zvichabatsira nyanzvi dzefizikisi kudzidza hunhu hwezvinhu zvikuru nechiedza. Basa ravo, rakaburitswa mumapepanhau esainzi ane mukurumbira, rinogonawo kubatsira kugadzira malaser anoshanda zvakanyanya ekushandisa muminda yakasiyana-siyana kubva pakurapa kusvika pakugadzira.

Iyolasermudziyo uyu wakagadzirwa nezvinhu zvakakosha zvinonzi photonic topological insulator. Photonic topological insulators inokwanisa kutungamira ma photon (mafungu nezvidimbu zvinoumba chiedza) kuburikidza nepakati pezvinhu zvakakosha mukati mechinhu, uku ichidzivirira kuti zvidimbu izvi zvisapararire muchinhu chacho. Nekuda kweizvi, topological insulators inogonesa ma photon akawanda kushanda pamwe chete. Midziyo iyi inogonawo kushandiswa se "topological quantum simulators," zvichibvumira vaongorori kudzidza quantum phenomena - mitemo yefizikisi inodzora zvinhu pazviyero zvidiki kwazvo - muma mini-labs.
"Izvotopological ye photonicMuchina wekudzivirira muviri watakagadzira wakasiyana. Unoshanda patembiricha yemumba. Uku kufambira mberi kukuru. Kare, zvidzidzo zvakadaro zvaingoitwa chete uchishandisa michina mikuru, inodhura yekutonhodza zvinhu muvacuum. MaLABS mazhinji ekutsvagisa haana michina yerudzi urwu, saka mudziyo wedu unogonesa vanhu vakawanda kuita rudzi urwu rwekutsvagisa kwefizikisi murabhoritari, "akadaro purofesa mubatsiri weRensselaer Polytechnic Institute (RPI) muDhipatimendi reSainzi yeZvinhu neUinjiniya uye munyori mukuru wechidzidzo. Chidzidzo ichi chaive nesampuro diki, asi mhedzisiro yacho inoratidza kuti mushonga mutsva waratidza kushanda kwakakosha mukurapa chirwere ichi chisingawanzoitiki chemajini. Tinotarisira kusimbisa mhedzisiro iyi mumiedzo yekiriniki yeramangwana uye zvingangotungamira kune sarudzo itsva dzekurapa varwere vane chirwere ichi." Kunyangwe saizi yemuenzaniso wechidzidzo ichi yaive diki, zvakawanikwa zvinoratidza kuti mushonga mutsva uyu waratidza kushanda kwakakosha mukurapa chirwere ichi chisingawanzoitiki chemajini. Tinotarisira kusimbisa mhedzisiro iyi mumiedzo yekiriniki yeramangwana uye zvingangotungamira kune sarudzo itsva dzekurapa varwere vane chirwere ichi."
"Iri idanho guru mukusimudzira ma lasers nekuti chiyero chedu chemuchina wekupisa kwemukamuri (huwandu hwesimba hunodiwa kuti chishande) chakaderera kanomwe pane michina yekare ye cryogenic," vaongorori vakawedzera. Vaongorori veRensselaer Polytechnic Institute vakashandisa nzira imwecheteyo yakashandiswa neindasitiri ye semiconductor kugadzira ma microchips kugadzira mudziyo wavo mutsva, izvo zvinosanganisira kurongedza mhando dzakasiyana dzezvinhu layer nelayer, kubva paatomu kusvika pa level yemamorekuru, kugadzira zvivakwa zvakanaka zvine hunhu hwakasiyana.
Kuita kutimudziyo we lasers, vaongorori vakagadzira mapuratifomu matete kwazvo e selenide halide (kristaro yakagadzirwa ne cesium, lead ne chlorine) uye vakaisa ma polymers ane mapatani paari. Vakabatanidza mapuratifomu aya e crystal nema polymers pakati pezvinhu zvakasiyana-siyana zve oxide, zvichikonzera chinhu chine ukobvu hwema microns maviri uye kureba uye upamhi hwema microns zana (avhareji yehupamhi hwebvudzi remunhu i100 microns).
Vaongorori pavakaona laser pachishandiso chelaser, patani yetriangle inopenya yakaonekwa pachiratidziro chekugadzira zvinhu. Patani yacho inosarudzwa nekugadzirwa kwechishandiso uye imhedzisiro yehunhu hwetopological hwelaser. "Kukwanisa kudzidza quantum phenomena patembiricha yemukamuri itarisiro inonakidza. Basa idzva raProfessor Bao rinoratidza kuti materials engineering inogona kutibatsira kupindura mimwe yemibvunzo mikuru musainzi," akadaro dean weinjiniya weRensselaer Polytechnic Institute.
