Umucyo muto wa Modulator ya Modulator hamwe nimbaraga zo hasi zavutse

Mu myaka yashize, abashakashatsi baturutse mu bihugu bitandukanye bakoresheje fosictique yinjijwe mu buryo buhuje kandi bagashyira mu bikorwa byihuta bya 5G, imiyoboro ya Chip, n'imodoka zigenga. Kugeza ubu, hamwe no gukomeza gushimangira iki cyerekezo cy'ubushakashatsi, abashakashatsi batangiye gukora ubujyambere mu buryo bwimbitse bw'amazi magufi kandi bateza imbere ibirahuri, ARRBRAD / HARBRUD

Ubunini bunini bwa modulator yicyiciro cya optique nigice cya optique ya optyystem ya optique ya optique hamwe nubusa-umwanya wa wavefront. Izi nyubako zombi za prima ni ngombwa kugirango umenyeshe porogaramu zitandukanye. Ariko, kuri modulati ya optique mubice bigaragara, biragoye cyane kubahiriza ibisabwa byoherezwa mu maboko yo hejuru no guhindura byinshi icyarimwe. Kugirango uhuze iki gisabwa, ndetse na Nitride ya Silicon cyane na Litiona ikeneye ibikoresho bya Niobate bigomba kongera amajwi no gukoresha amashanyarazi.

Kugira ngo iki kibazo, Michal Lipson na Nanfang Yu wa kaminuza ya Columbiya yateguye Modulator ya The Optic Nitric ishingiye kuri resonator ya Adiabatiya. Bagaragaje ko resonator ya Micro-Impeta ikorera muri leta ikomeye. Igikoresho kirashobora kugera ku byiciro byahinduwe hamwe nigihombo gito. Ugereranije na Pase ya Savegaide isanzwe, igikoresho gifite byibuze gahunda yo kugabanya ubunini mumwanya no gukoresha amashanyarazi. Ibikubiyemo bifitanye isano byasohotse muri fosics ya kamere.

Michal Limson, umuhanga mu buryo bukomeye mu murima wa Photonike ihuriweho, ishingiye kuri Silicon nitride ya Silicon, yagize ati: "Urufunguzo rw'igisubizo categanijwe ni ugukoresha mu bita byiswe Leta zidasanzwe."

Reporicator optique nimiterere yubusa, ishobora guhindura ibipimo bito byoroshye mubice bihinduka binyuze mumitsindino nyinshi zo mumucyo. Muri rusange, irashobora kugabanywamo ibice bitatu bitandukanye: "Muguhuza" na "munsi ya comping." Guhuzagurika "na" guhuza bikomeye. " Among them, “under coupling” can only provide limited phase modulation and will introduce unnecessary amplitude changes, and “critical coupling” will cause substantial optical loss, thereby affecting the actual performance of the device.

Kugirango ugere ku byiciro bya 2π hamwe na amplitution amplitude, itsinda ryubushakashatsi ryakoresheje micoring muri leta ya "guhuza bikomeye". Imbaraga zigenga hagati ya micororing na "bisi" byibuze inshuro icumi zirengere kubura micororing. Nyuma yuruhererekane rwibishushanyo no guhitamo, imiterere yanyuma yerekanwe kumashusho hepfo. Iyi ni impeta yumvikana ifite ubugari bwatangiriye. Igice gito cya Waveguide kigutezimbere imbaraga za optique hagati ya "bisi" na micro-coil. Igice kinini cya Wavegue Gutakaza urumuri Microrollang yagabanutse mukugabanya gutatanya neza.

Heqing Huang, umwanditsi wa mbere wimpapuro, yagize ati: "Twashizeho ibintu bike, kandi bikazigama, ndetse no kugabanya amashanyarazi make kuri 5 gusa na Π. Itandukaniro rya Amplitude ryashyizwe munsi ntabwo ari munsi ya 10%. Ni ikihe gake cyane ni uko iyi Modulator ifite akamaro kanini kubururu nubugereki bugoye cyane muri strectrum. "

Ubu nanfang yu yerekanye ko nubwo ari kure yo kugera kurwego rwo guhuza ibicuruzwa bya elegitoroniki, akazi kabo karahagaritse icyuho hagati ya fotokisi hamwe na elegitoroniki. Ati: "Niba tekinoroji ya modulator ya mbere yemeye gusa guhuza abanyeshuri 100 wa Waveguide yatanze ikirenge cya chip n'ingengo y'imari, noneho dushobora guhuza ibyiciro byingufu, noneho dushobora guhuza ibyiciro byingufu, noneho turashobora guhuza ibyiciro 10,000 kuri chip imwe kugirango tugere ku mikorere myinshi."

Muri make, ubu buryo bwo gushushanya burashobora gukoreshwa kuri elegalator ya electro-optique kugirango igabanye umwanya wigaruriwe hamwe na voltage. Irashobora kandi gukoreshwa mubindi bishushanyo mbonera nibindi bishushanyo byumvikane bitandukanye. Kugeza ubu, itsinda ry'abashakashatsi rifatanya kwerekana lidar igaragara igizwe na shifter yicyiciro cyashizeho gushingira kuri iyo mikuri. Mugihe kizaza, irashobora kandi gukoreshwa mubisabwa byinshi nko kongera ubumenyi bwa optique, laseri nshya, hamwe na optique nshya.
