Isi Nshya yaIbikoresho bya OpToelectronic

Abashakashatsi ku buhanga - Isiraheli Ikigo cy'ikoranabuhanga cyateje imbere spin yagenzuweOptical laserbishingiye ku gice kimwe cya atome. Ubu buvumbuzi bwarashobokaga imikoranire ya spin-ishingiye kuri atome imwe hamwe na photonic yatunganijwe mu buryo butambitse, ishyigikira ikibaya cya spice.
Igisubizo, cyatangajwe mu bikoresho kamere kandi gigaragara mu bushakashatsi bwayo, ritanga inzira yo kwiga kuzunguruka kuzunguruka kuzunguruka mu gitabo cya kera kandiSisitemu ya Quanies, kandi afungura inzira nshya yubushakashatsi hamwe na porogaramu ya eletroni na photon bazunguruka mubikoresho bya optoelectronic. Inkomoko ya Spin Optique ihuza uburyo bwa photon hamwe ninzibacyuho ya electron, itanga uburyo bwo kwiga kungurana amakuru hagati ya electrons hamwe no gufotoza no guteza imbere ibikoresho byateye imbere.

Spin Valley Opticavitire microkavitike ikwamirwa no guteranya inkomoko ya Photonic hamwe no guhinduranya asingry (akarere ka core yumuhondo) no guhinduranya ibishushanyo (akarere ka cyan).
Kugirango twubake aya masoko, ibisabwa ni ugukuraho indwara ya spin hagati y'ibihugu bibiri bitandukanye muri foton cyangwa igice cya elegit. Ibi mubisanzwe bigerwaho mugukoresha umurima wa rukuru munsi ya faraday cyangwa ngaruka, nubwo ubu buryo busaba umurima ukomeye wa magneti kandi ntushobora kubyara mikorobe. Ubundi buryo butanga icyizere bushingiye kuri sisitemu ya geometrike ikoresha umurima wa magneti ya artificique kugirango ubyare spin-kugabanywa ibihugu byafotowe mumwanya muto.
Kubwamahirwe, ibyambere bya Spin Spit byashinjwaga cyane muburyo buke cyane bwo kwamamaza, bitera imbogamizi mbi kuri spatial kandi yigihe gito. Ubu buryo nabwo bubangamiwe na spin-igenzurwa na spin igenzurwa nibikoresho byahagaritsweisoko yoroheje, cyane cyane mugihe habuze imirima ya magneti mubushyuhe bwicyumba.
Kugira ngo habeho ibihugu byo hejuru-Q Spin-Gucikamo ibice, Abashakashatsi bubatse inkombe ya Photonic hamwe n'ibishushanyo bitandukanye, harimo n'invange hamwe n'ibahasha ibangamiye hamwe na WS2, kugira ngo bigerweho mu mibande ya spin. Inzobere shingiro ya asice yakoreshejwe nabashakashatsi ifite ibintu bibiri byingenzi.
Umuyoboro ugenzurwa na vectice ya retacrocal yatewe na geometrike yicyiciro cya geometrike ihindagurika anisorgropic anisotropic anisotrous yabazwe. Iyi vector igabanya itsinda rya spin yangiza mumashami abiri ya spin-polarize kumurimo, uzwi nka photonic rushberg.
Igice kinini cya Q Symmetric (Quasi) kibazwa muri gahunda, aribo ± k (ploton spin spin spin spin spin ku nkombe yamashami ya spin, kora ikintu gihamye cya amplitude ingana.
Porofeseri Koren yagize ati: "Twakoresheje monolide ya ws2 nk'ibikoresho kuko iyi bande itaziguye itandukanya ikibaya cyihariye cya Pseudo-spin kandi yiga cyane nk'umuntu utwara amakuru mu kibaya cya Electron. By'umwihariko, ± K 'Ikibaya cyabo (bikaba kiba muburyo bwa dipole ya dishin-politike) irashobora gushimishwa n'umucyo ugereranya gutoranya ikibuga, bityo ugenzura neza amategeko agereranyaInkomoko ya Optique.
Mu rwego rumwe rwinjijwemo micron ikibaya, ± K 'Valley Exylens zijyanye na leta ya ± k spin kubera guhuza, kandi spin jusen laser ku bushyuhe bwicyumba bugerwaho no gutanga ibitekerezo bikomeye. Icyarimwe, thelaserUburyo bwo gukora iby'icyiciro cya mbere-cyigenga ± K 'ikibaya cyo gushaka igihombo gito cya sisitemu hanyuma wongere gushyiraho ihuriro rishingiye ku kibaya cya geometric giteganye na ± K.
Ikibaya Cohereresvants kuri uyu wakozeho laser Kurandura ibikenewe guhagarika ubushyuhe buke bwo gutanyanya. Byongeye kandi, igihombo gito cya Licolayer Laser Consar ya Raser irashobora gutegurwa na limp ya pompe (igena uburyo bwo kugenzura ubukana bwa laser no guhuza. "
Porofeseri Hasiman abisobanura: "AbahishurwaphotonicSpin Vallet Rashba atanga uburyo rusange bwo kubaka hejuru-gusohora spique. Ikibaya cya Coherere kigaragarira mu gice kimwe cya Spin Concavitity kizatuzanira intambwe imwe yo kugera kuri Quafficument Raporo yerekana amakuru hagati ya ± K 'Valley Slanson akoresheje rebits.
Kuva kera, ikipe yacu yateje imbere spink opics, gukoresha foton kuzunguruka nkigikoresho cyiza cyo kugenzura imyitwarire ya elecromagnetic. Muri 2018, dushishikajwe no kuzenguruka ikibaya cyasimbuka mu bikoresho bibiri, twatangiye umushinga w'igihe kirekire kugira ngo dukore iperereza ku bugenzuzi bugaragara bwa Atome-Spin Spin Ofttique. Dukoresha icyitegererezo kitari cyorezo cya Berry Cernera kugirango dukemure ikibazo cyo kubona iki cyiciro cya geometrike kiva mu kibaya kimwe.
Ariko, kubera kubura uburyo bukomeye bwo guhuza guhuza hagati ya Scetons, Ingendezi shingiro ryinshinga nyinshi muri Rashuba Inkomoko yumubiri umwe wagezweho. Iki kibazo kidutera imbaraga zo gutekereza kuri rashuba moderi yo hejuru fotosiye. Nyuma yo guhanga udushya ku mubiri, twashyize mu bikorwa Laseer Force-Lireer yasobanuwe muri iyi mpapuro. "
Iyi myage itanga inzira yo kwiga ibintu byahujwe na Chenomena mu murima wa kera kandi kanini, kandi bifungura inzira nshya yubushakashatsi no gukoresha ibikoresho bya spintronic na photonic optolectronic na photoucletronic na photoucletronic optolecronic.
