Lithium niobate tseem hu ua optical silicon. Muaj lus hais tias "lithium niobate yog kev sib txuas lus kho qhov muag uas silicon yog rau semiconductors." Qhov tseem ceeb ntawm silicon hauv kev hloov hluav taws xob hluav taws xob, yog li dab tsi ua rau kev lag luam zoo siab txog lithium niobate cov ntaub ntawv?
Lithium niobate (LiNbO3) yog hu ua "optical silicon" hauv kev lag luam. Ntxiv nrog rau cov txiaj ntsig zoo xws li lub cev zoo thiab tshuaj lom neeg ruaj khov, lub qhov rais dav optically pob tshab (0.4m ~ 5m), thiab loj electro-optical coefficient (33 = 27 pm / V), lithium niobate kuj yog ib hom siv lead ua uas muaj ntau yam raw khoom. cov khoom siv thiab tus nqi qis. Nws yog dav siv nyob rau hauv kev ua tau zoo lim, electro-optical li, holographic cia, 3D holographic zaub, nonlinear optical li, optical quantum kev sib txuas lus thiab hais txog. Hauv kev sib txuas lus kho qhov muag, lithium niobate feem ntau ua lub luag haujlwm ntawm lub teeb hloov kho, thiab tau dhau los ua cov khoom lag luam tseem ceeb hauv kev kub ceev electro-optical modulator tam sim no (Ib Modulator) kev lag luam.
Tam sim no, muaj peb lub ntsiab technologies rau lub teeb hloov kho nyob rau hauv kev lag luam: electro-optical modulators (Eo Modulator) raws li lub teeb silicon, indium phosphide thiablithium niobatecov khoom siv platforms. Silicon optical modulator feem ntau yog siv nyob rau hauv luv luv-ntau cov ntaub ntawv kev sib txuas lus transceiver modules, indium phosphide modulator yog tsuas yog siv nyob rau hauv nruab nrab-ntau thiab ntev-ntev optical kev sib txuas lus network transceiver modules, thiab lithium niobate electro-optical modulator (Eo Modulator) yog tsuas yog siv nyob rau hauv Ntev-ntau pob txha caj qaum network coherent kev sib txuas lus thiab ib leeg-yoj 100/200Gbps ultra-high-speed data centers. Ntawm cov saum toj no peb ultra-siab ceev modulator khoom platforms, nyias zaj duab xis lithium niobate modulator uas tau tshwm sim nyob rau hauv xyoo tas los no muaj lub bandwidth kom zoo dua uas lwm yam ntaub ntawv tsis phim.
Lithium niobate yog ib hom tshuaj inorganic, tshuaj formulaLIB 3, yog siv lead ua tsis zoo, ferroelectric siv lead ua, polarized lithium niobate siv lead ua nrog piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric thiab lwm yam khoom ntawm cov khoom, tib lub sij hawm nrog photorefractive nyhuv. Lithium niobate siv lead ua yog ib qho ntawm cov khoom siv tshiab inorganic, nws yog ib qho zoo piezoelectric zog pauv khoom, ferroelectric khoom, electro-optical khoom, lithium niobate raws li ib tug electro-optical khoom nyob rau hauv optical kev sib txuas lus plays lub luag hauj lwm nyob rau hauv lub teeb hloov.
Cov khoom siv lithium niobate, lub npe hu ua "optical silicon", siv cov txheej txheem micro-nano tshiab los ua kom cov txheej txheem silicon dioxide (SiO2) ntawm silicon substrate, khi cov lithium niobate substrate ntawm qhov kub thiab txias los tsim kom muaj qhov tawg, thiab thaum kawg tev. tawm ntawm lithium niobate zaj duab xis. Kev npaj nyias zaj duab xis lithium niobate modulator muaj qhov zoo ntawm kev ua haujlwm siab, tsis tshua muaj nqi, me me, ntau lawm, thiab kev sib raug zoo nrog CMOS thev naus laus zis, thiab yog kev sib tw daws teeb meem rau kev sib txuas ntawm qhov muag kub ceev yav tom ntej.
Yog tias qhov chaw ntawm lub tshuab hluav taws xob hloov pauv muaj npe tom qab cov khoom siv silicon uas ua rau nws ua tau, tom qab ntawd cov kev hloov pauv photonics tuaj yeem taug qab mus rau cov khoom siv lithium niobate, hu ua "optical silicon" lithium niobate yog cov khoom tsis muaj xim tsis muaj pob tshab uas ua ke nrog cov teebmeem photorefractive, nonlinear. cov teebmeem, cov teebmeem electro-optical, acousto-optical teebmeem, piezoelectric teebmeem thiab thermal teebmeem. Ntau yam ntawm nws cov khoom muaj peev xwm tswj tau los ntawm crystal muaj pes tsawg leeg, lub ntsiab doping, valence xeev tswj thiab lwm yam. Nws yog dav siv los npaj kho qhov muag waveguide, kho qhov muag hloov, piezoelectric modulator,electro-optical modulator, thib ob harmonic generator, laser zaus multiplier thiab lwm yam khoom. Hauv kev lag luam kev sib txuas lus kho qhov muag, modulators yog ib qho tseem ceeb hauv kev lag luam rau lithium niobate.
