Imikorere yo hejuru ultrafast laser ingano yintoki

Imikorere yo hejuruultrafast laseringano y'urutoki

Nk’uko ingingo nshya yasohotse mu kinyamakuru Science, abashakashatsi bo muri kaminuza y’Umujyi wa New York bagaragaje uburyo bushya bwo gukora imikorere-yo hejuruIbikoresho bya ultrafastkuri nanofotonike. Ubu buryo bwa miniaturizime-bufunzelaserIsohora urukurikirane rwa ultra-ngufi coherent pulses yumucyo mugihe cya femtosekond (trillionths yisegonda).

Ultrafast uburyo-bufunzelaseriIrashobora gukingura amabanga yigihe cyibihe byihuta, nko gushiraho cyangwa gucamo imigozi ya molekile mugihe cya reaction yimiti, cyangwa gukwirakwiza urumuri mubitangazamakuru bidurumbanya. Umuvuduko mwinshi, ubukana bwimpanuka, hamwe nubunini bwagutse bwa lazeri zifunze nazo zifasha tekinoroji ya fotone nyinshi, harimo amasaha ya atome ya optique, amashusho y’ibinyabuzima, na mudasobwa zikoresha urumuri mu kubara no gutunganya amakuru.

Ariko uburyo bugezweho bufunze lazeri buracyahenze cyane, sisitemu ya desktop isaba ingufu zigarukira kumikoreshereze ya laboratoire. Intego yubushakashatsi bushya nuguhindura iyi sisitemu nini ya chip ishobora kubyara umusaruro kandi igashyirwa mumurima. Abashakashatsi bifashishije lithium niobate (TFLN) yoroheje igaragara kugirango ibashe gukora neza no kugenzura neza impiswi ya laser bakoresheje ibimenyetso byamashanyarazi bya radiyo yo hanze. Itsinda ryahujije inyungu nyinshi za lazeri zo mu cyiciro cya III-V igice cya kabiri hamwe nubushobozi bwiza bwo gushiraho pulse ya TFLN nanoscale Photonic waveguides kugirango ikore lazeri isohora ingufu nyinshi zingana na 0.5 watts.

Usibye ubunini bwacyo, nubunini bwurutoki, ibyerekanwe bishya byerekana uburyo bwafunzwe na lazeri irerekana kandi imitungo myinshi lazeri gakondo idashobora kugeraho, nkubushobozi bwo guhuza neza igipimo cyisubiramo cyibisohoka hejuru y a ubugari bwa megahertz 200 muguhindura pompe. Iri tsinda ryizera ko rizagera kuri chip-nini, inshuro-itajegajega ikomoka ku mbuto binyuze mu buryo bukomeye bwa laser, ibyo bikaba ari ngombwa mu kumenya neza. Porogaramu zifatika zirimo gukoresha terefone zigendanwa mu gusuzuma indwara z’amaso, cyangwa gusesengura E. coli na virusi zangiza mu biribwa no mu bidukikije, no gufasha kugenda iyo GPS yangiritse cyangwa itaboneka.
