Imikorere yubwenge ya terahertz electro-optic modulator yatejwe imbere neza

Umwaka ushize, itsinda rya Sheng Zhigao, umushakashatsi mu kigo cyitwa High Magnetic Field Centre cya Hefei Institute of Physical Science, Ishuri Rikuru ry’Ubumenyi bw’Ubushinwa, ryateje imbere moderi ikora kandi ifite ubwenge ya terahertz electro-optique modulator ishingiye ku bushakashatsi bwa magnetiki bwo mu rwego rwo hejuru igikoresho. Ubushakashatsi bwatangajwe muri ACS Applied Materials & Interfaces.

Nubwo tekinoroji ya terahertz ifite ibimenyetso biranga ibintu byinshi kandi ikanashyirwa mubikorwa, ikoreshwa ryubwubatsi iracyafite imbogamizi mugutezimbere ibikoresho bya terahertz nibigize terahertz. Muri byo, igenzura rikora kandi ryubwenge rya terahertz kumurongo wo hanze nicyerekezo cyingenzi cyubushakashatsi muriki gice.

Intego yubushakashatsi bugezweho bwibice byingenzi bigize terahertz, Itsinda ryubushakashatsi ryavumbuye moderi ya terahertz ihangayikishije ishingiye kuri graphene yibikoresho bibiri. Ibikoresho byiza. 6, 1700877 (2018)], umuyoboro mugari wa Terahertz mugenzuzi wa moderi ushingiye kuri oxyde ifitanye isano cyane [Porogaramu ya ACS. Ibikoresho. Inter. 12. igishushanyo nuburyo bwo kugenzura hakoreshejwe uburyo bwa elegitoronike. Guhindura ibikorwa byinshi byo guhinduranya terahertz, gutekereza no kwinjiza bigerwaho (Ishusho a). Ibisubizo byerekana ko usibye guhererekanya no kwinjizwa, icyiciro cyo kugaragariza no kugaragariza gishobora nanone kugenzurwa cyane n’umuriro w’amashanyarazi, aho ubujyakuzimu bwo guhindura ibintu bushobora kugera kuri 99.9% naho icyiciro cyo kugaragariza gishobora kugera kuri ~ 180o (Ishusho b) . Igishimishije kurushaho, kugirango ugere kuri terahertz yubwenge igenzura amashanyarazi, abashakashatsi bakoze igikoresho gifite igitabo cyitwa "terahertz - amashanyarazi-terahertz" cyo gusubiza (Ishusho c). Hatitawe ku mpinduka zabaye muburyo bwo gutangira nibidukikije byo hanze, igikoresho cyubwenge gishobora guhita kigera kumurongo (uteganijwe) agaciro ka moderasiyo ya terahertz mumasegonda 30.

(a) Igishushanyo mbonera cya anamashanyarazi ya optiquebishingiye kuri VO2

.

(c) igishushanyo mbonera cyo kugenzura ubwenge

Iterambere rya terahertz ikora kandi ifite ubwengeamashanyarazi ya optiquebishingiye kubikoresho bya elegitoroniki bifitanye isano bitanga igitekerezo gishya cyo kumenya kugenzura ubwenge bwa terahertz. Uyu murimo washyigikiwe na gahunda nkuru y’ubushakashatsi n’iterambere ry’igihugu, Fondasiyo y’ubumenyi y’ubumenyi n’igihugu n’ikigega kinini cya Magnetic Field Laboratory Direction Fund yo mu Ntara ya Anhui.
