Igipimo cyo Kubabara Ukuri kiri murutonde rwa Kilohertz

Aherutse kwigira muri kaminuza ya siyansi n'ikoranabuhanga mu Bushinwa, wa kaminuza ya Guo Guangcan anyeshuri mu Bushinwa ahimbaza Micro-cassity yo kugenzura imirongo ya Optique (KHZ). Ibyagaragaye byasohotse mu itumanaho.
MicroCombs ya Soliton ishingiye kuri microkavitique optique yakunze gushishikazwa nubushakashatsi bukomeye mubushakashatsi muburyo bwa pressescopy namasaha ya Optique. Ariko, kubera urusaku rwibidukikije kandi rwa laser hamwe ningaruka zidasanzwe muri microcavitity, ituze rya microcomb nyinshi, riba inzitizi ikomeye muburyo bukoreshwa murwego rwo hasi. Mu kazi kashize, abahanga barahamye kandi bagenzuraga ibigo bya optique mu kugenzura urutonde rwibikoresho cyangwa geometrie ya microCavizitiwe mu buryo busanzwe bwo kugenzura inshuro nyinshi, gusubiramo ibimamara. Ibi bigabanya cyane ibimamara bike-byoroheje mubintu bifatika byerekana neza ibiciro bya precipée, fotowave ya microwave, uburyo bwiza, nibindi.

Kugira ngo iki kibazo gikemuke, itsinda ry'abashakashatsi ryasabye uburyo bushya bw'umubiri bwo kumenya amabwiriza yigenga yigenga hamwe ninshuro yo gusubiramo inshuro ya optique. Mu kwinjiza uburyo bubiri busanzwe bwo kugenzura, itsinda rishobora kugenzura ryigenga ku mabwiriza atandukanye ya micro-cavity, kugirango tugere ku kugenzura burundu menyo ya optique. Ubu buryo bwo gutatanya kugenzura kwisi yose ihuriweho na photonic nka silicon nitride na lithium niobate, byakizwe cyane.

Ikipe yubushakashatsi yakoresheje laser laser na laser ya auxiliary kugirango bagenzure ubwigenge muburyo busanzwe bwa microcadity kugirango habeho gushikama kubuntu hamwe ninjiza yigenga yo gusubiramo inshuro nyinshi. Ukurikije ibimamara bya optique, itsinda ryubushakashatsi ryerekanye amafaranga yihuse, ya porogaramu yo gupima amafaranga uko bishakiye no kuyashyira mu gaciro k'umuraba, yerekana ko wangiza uburebure bw'uburebure bwa Kilohertz n'ubushobozi bwo gupima uburebure bwinshi icyarimwe. Ugereranije nibisubizo byubushakashatsi bwabanje, ibipimo byukuri byagezweho nitsinda ryubushakashatsi ryageze ku mategeko atatu yo gutera imbere cyane.

MicroCombs ya Soliton yagaragaye muri ubu bushakashatsi bwashyizeho urufatiro rwo gushyira mu bikorwa ibiciro bike, bihujwe no gupima neza, isaha yo gupima neza, intebe n'itumanaho n'itumanaho n'itumanaho n'itumanaho.
