Gitoya Kugaragara Umucyo Icyiciro Modulator hamwe nimbaraga nke zavutse

Mu myaka yashize, abashakashatsi baturutse mu bihugu bitandukanye bakoresheje fotonike ihuriweho kugira ngo bashobore kumenya neza imikoreshereze y’umucyo utagira urumuri kandi babishyira mu muyoboro wihuse wa 5G, ibyuma bifata ibyuma, ndetse n’imodoka yigenga. Kugeza ubu, hamwe n’ubujyakuzimu bwimbitse bwiki cyerekezo cyubushakashatsi, abashakashatsi batangiye gukora ubushakashatsi bwimbitse bwerekana urumuri rugufi rugaragara kandi batezimbere uburyo bwagutse, nka chip-urwego LIDAR, AR / VR / MR (yazamuye / igaragara / hybrid) Ukuri) Ikirahure, kwerekana holographiche, chipant itunganya chip, optogenetic probe yatewe mubwonko, nibindi.

Ingano nini yo guhuza optique ya moderi ya moderi niyo ntandaro ya optique ya sisitemu ya optique ya on-chip optique ya marike hamwe nubusa-umwanya wubusa. Iyi mikorere yombi prima ryingirakamaro mugushira mubikorwa bitandukanye. Nyamara, kuri optique yicyiciro cya modulator muburyo bugaragara bwurumuri, biragoye cyane kubahiriza ibisabwa byogukwirakwiza kwinshi hamwe no guhinduka cyane icyarimwe. Kugira ngo ibyo bisabwa bishoboke, ndetse nibikoresho bya silicon nitride hamwe nibikoresho bya lithium niobate bigomba kongera ubwinshi no gukoresha ingufu.

Kugira ngo iki kibazo gikemuke, Michal Lipson na Nanfang Yu bo muri kaminuza ya Columbia bakoze igishushanyo mbonera cya silicon nitride ya moderi ya moderi ya moderi ishingiye kuri adiabatic micro-ring resonator. Bagaragaje ko resonator ya micro-ring ikora muburyo bukomeye bwo guhuza. Igikoresho kirashobora kugera ku cyiciro cyo guhindura hamwe nigihombo gito. Ugereranije na moderi isanzwe ya moderi ya moderi, igikoresho gifite byibura gahunda yo kugabanya ubunini mumwanya no gukoresha ingufu. Ibirimo bijyanye byasohotse muri Kamere Photonics.

Michal Lipson, impuguke ikomeye mu bijyanye na fotonike ihuriweho, ishingiye kuri nitride ya silicon, yagize ati: “Urufunguzo rw’igisubizo twatanze ni ugukoresha resonator optique kandi tugakorera mu cyiswe leta ikomeye.”

Optical resonator nuburyo bufatika cyane, bushobora guhindura indangagaciro ntoya ihindagurika mugice cyimpinduka zinyuze mumirongo myinshi yumucyo. Muri rusange, irashobora kugabanywamo ibice bitatu bitandukanye byakazi: "munsi yo guhuza" na "munsi yo guhuza." Gukomatanya gukomeye ”na“ gukomera gukomeye. ” Muri byo, "munsi yo guhuza" irashobora gutanga icyiciro gito gusa kandi ikazana impinduka zidakenewe za amplitude, kandi "guhuza bikomeye" bizatera igihombo kinini, bityo bikagira ingaruka kumikorere yibikoresho.

Kugirango ugere ku cyiciro cya 2π cyuzuye hamwe nimpinduka ntoya ya amplitude, itsinda ryubushakashatsi ryakoresheje microring muri "gukomera gukomeye". Imbaraga zo guhuza hagati ya microring na "bus" byibuze byibuze inshuro icumi kurenza igihombo cya microring. Nyuma yuruhererekane rwibishushanyo no gutezimbere, imiterere yanyuma irerekanwa mumashusho hepfo. Iyi ni impeta yumvikana n'ubugari bwafashwe. Igice kigufi cyogutezimbere imbaraga zo guhuza imbaraga hagati ya "bus" na micro-coil. Igice kinini cya waveguide Igice cyo gutakaza urumuri rwa microring kigabanuka mukugabanya optique ikwirakwizwa kumuhanda.

Heqing Huang, umwanditsi wa mbere w’uru rupapuro, na we yagize ati: “Twashizeho miniature, izigama ingufu, ndetse n’igihombo gito cyane kigaragara cyerekana moderi yumucyo ufite radiyo ya 5 mkm gusa na π-icyiciro cyo gukoresha amashanyarazi gusa 0.8 mW. Itangizwa rya amplitude itandukanye iri munsi ya 10%. Ikidasanzwe ni uko iyi modulator ikora neza cyane kubururu bugoye cyane nicyatsi kibisi mugice kigaragara. ”

Nanfang Yu yerekanye kandi ko nubwo batagera ku rwego rwo guhuza ibicuruzwa bya elegitoroniki, akazi kabo kagabanije cyane itandukaniro riri hagati y’ifoto ya fotonike na elegitoroniki. Ati: "Niba ikoranabuhanga ryabanjirije modulator ryemereye gusa guhuza 100 moderi ya moderi ya moderi ihabwa chip imwe hamwe na bije yingufu, noneho dushobora guhuza ibice 10,000 byimuka kuri chip imwe kugirango tugere kumikorere iruhije."

Muri make, ubu buryo bwo gushushanya burashobora gukoreshwa kuri moderi ya electro-optique kugirango igabanye umwanya ukoreshwa hamwe na voltage ikoreshwa. Irashobora kandi gukoreshwa mubindi bice byerekanwe hamwe nubundi buryo butandukanye bwa resonator. Kugeza ubu, itsinda ry’ubushakashatsi rifatanya kwerekana kwerekana LIDAR igaragara igizwe na feri yo guhinduranya ibice bishingiye kuri microrings. Mugihe kizaza, irashobora kandi gukoreshwa mubikorwa byinshi nko kuzamura optique idafite umurongo, laseri nshya, hamwe na kwant optique.
