Fin film lithium niobate ibikoresho na fin film lithium niobate modulator

Ibyiza n'akamaro ka Filime yoroheje Litium Niobate muri Micwave Technology Technology

Microwave Phoon Technologyhas the advantages of large working bandwidth, strong parallel processing ability and low transmission loss, which has the potential to break the technical bottleneck of traditional microwave system and improve the performance of military electronic information equipment such as radar, electronic warfare, communication and measurement and control. Ariko, sisitemu ya microwave ishingiye kubikoresho byihariye bifite ibibazo bimwe na bimwe nkibinini byinshi, uburemere bukabije no guhagarika uburemere bwa platon prology platon na airborf. Kubwibyo, ihuriweho na Microwave Photon ikoranabuhanga ryingenzi ryo guca imari ya microwave muri sisitemu yamakuru ya elegitoroniki ya gisirikare no gutanga ikinamico ku nyungu za micwave tekinoroji ya japae telefoni.

Kugeza ubu, tekinoroji ya photonique ishingiye ku bufatanye na Sinewike ya Siotonic hamwe na tekinoroji yo guhuza ifu ishingiye ku bufatanye yarushijeho gukura nyuma y'iterambere mu rwego rw'itumanaho ryiza, kandi ibicuruzwa byinshi byashyizwe ku isoko. Ariko, kubisabwa na Photon ya Microwave, hari ibibazo bimwe na bumwe muri ubwo bwoko bubiri bwa tekinoroji yo guhuza photon, urugero, optique idafite gahunda ya sidulator na sodulator ya modulator na sodulator ishimishije ya mokona ya japave yakurikiranye na tekinoroji ya microton. Kurugero, silicon optique ya optique ibona inzira nziza yo guhinduranya, haba ingaruka nziza-piezoelectric, ibikoresho byo gutangiza ubushyuhe, bikaba bishobora kubahiriza gusiganwa ku mashanyarazi kandi bikaba bidashobora guhuza imigenzo ya Beam na Microwave Facwave Fackave yihuta.

Lithium niobate yahoraga ihitamo ryambere kumuvuduko mwinshiGuhindura electro-optiqueIbikoresho kubera umurongo mwiza mwiza electro-optique. Ariko, imitima ya lithium niobateModutor ya electro-optiqueikozwe muri lithium ariobate ariobate ibikoresho bya kirisiti, kandi ingano yibikoresho ni nini cyane, itujuje ibikenewe byikoranabuhanga rya fototon. Nigute ushobora guhuza ibikoresho bya niobate hamwe numurongo electro-optique coeeffic muri sisitemu yikoranabuhanga ya Phoon ya Photon yahindutse tekinoroji ya photon yabaye umushakashatsi. Muri 2018, itsinda ry'abashakashatsi baturutse muri kaminuza ya Harvard muri Amerika bwarabanje kugenzaga tekinoroji yo guhuza iplamique, kubera ko ikoranabuhanga rifite intego yo kwishyira hamwe, kubera ko ikoranabuhanga rifite intego yo kwishyira hamwe, kubera ko ikoranabuhanga rifite intego yo kwishyira hamwe, kubera ko telefone nini ya electro-optique. Dukurikije ibisobanuro bya Photon Photon Porogaramu, iyi mpapuro isubiramo ingaruka n'akamaro k'ikoranabuhanga rya photon rishingiye kuri filime ya Flaton rishingiye ku iterambere ry'ikoranabuhanga rya japave.

Film yoroheje lithium niobate ibikoresho na firime yorohejelithium niobate modulator
Mu myaka ibiri ishize, ubwoko bushya bwibikoresho bya Niobate byagaragaye, ni ukuvuga filime ya Niobate ishishikajwe na lithium ya silica impapuro. Ridge waveguide nuburebure bwa Nanometero zirenga 100 irashobora gutondekwa kubikoresho bya tithium byahinduwe na 0.02 bitandukanya umurongo wa 1 .8 hamwe numurima wa microwave mugihe ushushanya modulator. Rero, ni byiza kugera kuri enyerdonage yo hepfo-umugozi wa disdulation hamwe nimiterere nini mu burebure bugufi.

Kugaragara k'umuvuduko gake lithium niobate submicroron waveguide kumena icumu rya voltage yo gutwara ibinyabiziga gakondo ya litium niobate ya electro-optic. Umwanya wa electrode urashobora kugabanuka kugeza ~ 5 μm, hamwe no gukosorwa hagati yumurima wamashanyarazi hamwe na progaramu ya optaque yiyongereye cyane, kandi vm ya Optique yiyongereye cyane, kandi VM · igabanuka kuva kuri 14 km kugeza munsi ya 2.8. Kubwibyo, munsi yigice kimwe-cyumuraba, uburebure bwigikoresho burashobora kugabanywa cyane ugereranije na modulator gakondo. Muri icyo gihe, nyuma yo gutegura ibipimo by'ubugari, ubunini no mu gihe cyo gutembera, nkuko bigaragara ku gishushanyo, Modulator irashobora kugira ubushobozi bwo guhuza uldulationth irenze 100 ghz.

Igishushanyo

Igishushanyo.2 (a) Waveguide na electrode Imiterere na (B) Coreplate ya Ln Modulator

Kugereranya filime yoroheje lithium niobate modulators gakondo ya lithilation ya Niobate, Modulator ya Silicon na Indium (InP) hamwe nibindi bikoresho bya Optique, ibipimo byingenzi byo kugereranya birimo:
.
.
(3) Gutakaza Optical Gutakaza (DB) mu karere ka modulation. Irashobora kugaragara kumeza ko filime yoroheje lithium niobate modulator igaragara muburyo bugaragara mu moko, igice cya kabiri-cyumuranga cya opporiste, igihombo cya optique nibindi.

Silicon, nk'igifu cyurufatiro rwa OPTTOLESTORTLETRESTMS, cyatejwe imbere kugeza ubu, inzira irakuze, micoaturisation yacyo ifasha cyane guhuza / ibikoresho byayo, na Modulator yacyo yabaye mu itumanaho ryiza. Uburyo bwa electro-optique uburyo bwa silikoni bwa silicon ahanini ni abatwara igihangange, gutera inshinge hamwe no kwirundanya. Muri bo, umutako wa modulator ni byiza kuri gahunda yo gutambuka umurongo, ariko kubera ko ikwirakwizwa rya optique rikwiranye n'uko hashyizweho intera yo kugoreka kwa kabiri, iyi ngaruka izashyiraho uburyo bwo kugoreka ku mucyo, izi ngaruka za interineti yo kugoreka ku mucyo, zizaganisha ku kugabanya ibintu bya Opduction amplitude no kwerekana ibimenyetso.

Modulator ya InP ifite ingaruka zikomeye za electro-optique, hamwe nurwego rwibintu byinshi bya quampti-hejuru cyane hamwe na modulator ya voltage ntoya hamwe na 0.156w · mm. Ariko, itandukaniro ryurutonde rutunganya hamwe numurongo wamashanyarazi urimo umurongo namagambo adasanzwe, kandi kwiyongera kwumurima wamashanyarazi bizatuma ingaruka za kabiri. Kubwibyo, silicon na inp modulator ya elegique ikeneye gushyira kubogama kugirango bakore pn ihumure mugihe bakorera, kandi PN izazana igihombo cyihariye kumucyo. Nyamara, Ingano ya modulator yibi byombi ni nto, ingano ya modulatricor yubucuruzi ni 1/4 ya modulator ya Ln. Imyitwarire minini yo gukora neza, ikwiranye n'ubucucike bwinshi hamwe nintera ngufi nziza ya digital optique ikwirakwiza amakuru nkamakuru. Ingaruka ya electro-optique ya Niobate niobate idafite uburyo bwo kwinjira mu mucyo no gutakaza bike, bikwiranye nintera ndendeItumanaho ryizahamwe n'ubushobozi bunini no gutanga urugero. Muri porogaramu ya microwave, coefto-optique ya electro-optique ya si na the ninkin, bidakwiriye sisitemu ya microwave ikurikirana umurongo muremure na dinamike nini. Ibikoresho bya Niobate birakwiriye cyane kuri Photon Photon gusaba kubera umurongo wacyo rwose electro-optique moduction.
