Izixhobo ezincinci kunye nokusebenza kakuhleiilaser
Rensselaer Polytechnic Institute abaphandi baye benza aisixhobo laseroko kuphela ububanzi beenwele zomntu, eziya kunceda iingcali zefiziksi ukuba zifunde iimpawu ezisisiseko zento kunye nokukhanya. Umsebenzi wabo, opapashwe kwiijenali zenzululwazi ezidumileyo, unokunceda ekuphuhliseni iilaser ezisebenza ngokufanelekileyo ukuze zisetyenziswe kumacandelo asusela kumayeza ukuya kwimveliso.
Ilaserisixhobo senziwe ngezinto ezikhethekileyo ezibizwa ngokuba yi-photonic topological insulator. Ama-insulators e-Photonic topological insulators ayakwazi ukukhokela i-photons (amaza kunye neengqungquthela ezenza ukukhanya) ngokusebenzisa i-interfaces ekhethekileyo ngaphakathi kwezinto eziphathekayo, ngelixa zikhusela ezi ngqungquthela ukuba zisasazeke kwizinto ngokwazo. Ngenxa yale propati, ii-insulators ze-topological zenza ukuba iifotoni ezininzi zisebenze kunye xa zizonke. Ezi zixhobo zisenokusetyenziswa njenge-topological "quantum simulators," evumela abaphandi ukuba bafunde i-quantum phenomena - imithetho yendalo elawula izinto kwimilinganiselo emincinci kakhulu - kwiilebhu ezincinci.
“Ii-photonic topologicali-insulator esiyenzileyo yahlukile. Isebenza kwiqondo lokushisa. Le yinkqubela enkulu. Ngaphambili, amaphononongo anjalo ayenokwenziwa kuphela kusetyenziswa izixhobo ezikhulu, ezibiza kakhulu ukupholisa izinto kwivacuum. Uninzi lweLABS zophando azinalo olu hlobo lwezixhobo, ke isixhobo sethu senza ukuba abantu abaninzi benze olu hlobo lophando lwefiziksi esisiseko kwilebhu, utshilo uRensselaer Polytechnic Institute (RPI) unjingalwazi oncedisayo kwiSebe lezeNzululwazi kunye nobuNjineli kunye nophezulu. umbhali wesifundo. Uphononongo lwalunobungakanani besampulu encinci ngokwentelekiso, kodwa iziphumo zibonisa ukuba ichiza lenoveli libonise ukusebenza okubalulekileyo ekunyangeni olu phazamiseko lunqabileyo lwemfuzo. Sijonge phambili ekuqinisekiseni ngakumbi ezi ziphumo kulingo lwezonyango lwexesha elizayo kwaye ezinokukhokelela kukhetho olutsha lonyango kwizigulana ezinesi sifo. ” Nangona ubungakanani besampulu yophononongo bebuncinci, iziphumo zibonisa ukuba eli chiza linoveli libonise ukusebenza okubalulekileyo ekunyangeni le ngxaki inqabileyo yemfuza. Sijonge phambili ekuqinisekiseni ngakumbi ezi ziphumo kulingo lwezonyango lwexesha elizayo kwaye ezinokukhokelela kukhetho olutsha lonyango kwizigulana ezinesi sifo. ”
"Eli linyathelo elikhulu eliya phambili ekuphuhliseni i-lasers ngenxa yokuba iqondo lobushushu begumbi lethu (inani lamandla afunekayo ukuze lisebenze) liphantsi ngokuphindwe kasixhenxe kunezixhobo zangaphambili ze-cryogenic," abaphandi bongezelela. Abaphandi beRensselaer Polytechnic Institute basebenzise ubuchule obufanayo obusetyenziswa lishishini le-semiconductor ukwenza ii-microchips ukwenza isixhobo sabo esitsha, esibandakanya ukupakishwa kweentlobo ezahlukeneyo zezixhobo zomaleko ngokwemaleko, ukusuka kwiathom ukuya kwinqanaba lemolekyuli, ukwenza izakhiwo ezifanelekileyo ezineempawu ezithile.
Ukwenza iisixhobo lasers, abaphandi bakhulisa iipleyiti ezicwecwe kakhulu ze-selenide halide (ikristale eyenziwe ngecesium, ilothe kunye neklorini) kunye neepolymers ezifakwe kuzo. Badibanisa la macwecwe ekristale kunye neepolymers phakathi kwezixhobo ezahlukeneyo ze-oxide, okukhokelela kwinto emalunga neemicrons ezi-2 ubukhulu kunye ne-100 ye-microns ubude nobubanzi (umndilili wobubanzi beenwele zomntu yi-100 microns).
Xa abaphandi bekhazimlisa i-laser kwisixhobo se-laser, ipateni engunxantathu ekhanyayo yavela kujongano loyilo lwezinto. Ipatheni inqunywe yi-design yesixhobo kwaye sisiphumo seempawu ze-topological ze-laser. “Ukukwazi ukufunda i-quantum phenomena kwiqondo lobushushu legumbi lithemba elinika umdla. Umsebenzi kaNjingalwazi uBao ubonisa ukuba ubunjineli bezinto eziphathekayo bunokusinceda siphendule eyona mibuzo mikhulu kwezenzululwazi.” Umphathi wobunjineli weRensselaer Polytechnic Institute uthe.
