Eo Modulator Series: Chifukwa chiyani lithiamu niobate imatchedwa silicon optical

Lithium niobate imadziwikanso kuti silicon optical. Pali mawu akuti "lithium niobate ndi kulumikizana ndi kuwala zomwe silicon imachita kwa semiconductors." Kufunika kwa silicon mu kusintha kwamagetsi, ndiye chimapangitsa makampani kukhala ndi chiyembekezo chokhudza zida za lithiamu niobate?

Lithium niobate (LiNbO3) imadziwika kuti "optical silicon" pamsika. Kuphatikiza pazabwino zachilengedwe monga kukhazikika kwathupi ndi mankhwala, zenera lowoneka bwino (0.4m ~ 5m), komanso ma electro-optical coefficient (33 = 27 pm/V), lithiamu niobate ndi mtundu wa kristalo wokhala ndi zobiriwira zambiri. magwero zakuthupi ndi mtengo wotsika. Amagwiritsidwa ntchito kwambiri muzosefera zogwira ntchito kwambiri, zida za electro-optical, holographic storage, 3D holographic display, nonlinear Optical devices, optical quantum communication ndi zina zotero. Pankhani ya kulumikizana kwa kuwala, lithiamu niobate makamaka imagwira ntchito yosinthira kuwala, ndipo yakhala chinthu chodziwika bwino pamagetsi amakono othamanga kwambiri a electro-optical modulator(Eo Modulator) msika.

Pakadali pano, pali njira zitatu zazikuluzikulu zosinthira kuwala m'makampani: ma electro-optical modulators (Eo Modulator) kutengera kuwala kwa silicon, indium phosphide ndilithiamu niobatensanja zakuthupi. Silicon optical modulator imagwiritsidwa ntchito makamaka pama transceiver afupikitsa a data, indium phosphide modulator imagwiritsidwa ntchito makamaka pama module apakati komanso atalitali atalitali, ndipo lithiamu niobate electro-optical modulator (Eo Modulator) imagwiritsidwa ntchito kwambiri maukonde atalitali amsana olumikizana amalumikizana ndi ma wave 100/200Gbps ma data apamwamba kwambiri. Pakati pa pamwamba atatu kopitilira muyeso-mkulu liwiro modulator zinthu nsanja, woonda filimu lifiyamu niobate modulator amene anatulukira m'zaka zaposachedwapa ali ndi bandiwifi mwayi kuti zipangizo zina sizingafanane.

Lithium niobate ndi mtundu wa zinthu zopanda organic, mankhwalaLiNbO3, ndi kristalo woipa, crystal ferroelectric, polarized lithiamu niobate crystal ndi piezoelectric, ferroelectric, photoelectric, optics nonlinear, thermoelectric ndi zina zakuthupi, panthawi imodzimodziyo ndi photorefractive effect. Lithium niobate crystal ndi imodzi mwazinthu zatsopano zomwe zimagwiritsidwa ntchito kwambiri, ndizinthu zabwino zosinthira mphamvu za piezoelectric, ferroelectric material, electro-optical material, lithiamu niobate monga electro-optical material mu kuwala kwa kuwala kumagwira ntchito posintha kuwala.

Lifiyamu niobate zakuthupi, lotchedwa "kupenya pakachitsulo", amagwiritsa ntchito njira yaposachedwa yaying'ono-nano kutenthetsa silicon dioxide (SiO2) wosanjikiza pa gawo lapansi la silicon, kumangiriza gawo lapansi la lithiamu niobate pa kutentha kwakukulu kuti amange cleavage pamwamba, ndipo pomaliza peel. pa filimu ya lithiamu niobate. The okonzeka filimu woonda lithiamu niobate modulator ali ndi ubwino mkulu ntchito, mtengo wotsika, kukula kochepa, kupanga misa, ndi n'zogwirizana ndi CMOS luso, ndipo ndi njira mpikisano kwa mkulu-liwiro kuwala interconnection m'tsogolo.

Ngati likulu la kusintha kwamagetsi limatchulidwa ndi zinthu za silicon zomwe zinapangitsa kuti zitheke, ndiye kuti kusintha kwa photonics kungayambike kuzinthu za lithiamu niobate, zomwe zimadziwika kuti "optical silicon" lithiamu niobate ndi chinthu chopanda utoto chomwe chimaphatikizapo zotsatira za photorefractive, zopanda malire. zotsatira, electro-optical zotsatira, acousto-optical zotsatira, piezoelectric zotsatira ndi matenthedwe. Zambiri mwazinthu zake zimatha kuwongoleredwa ndi mawonekedwe a crystal, doping element, control valence state ndi zina. Amagwiritsidwa ntchito kwambiri pokonzekera optical waveguide, optical switch, piezoelectric modulator,electro-optical module, jenereta yachiwiri ya harmonic, kuchulukitsa pafupipafupi kwa laser ndi zinthu zina. M'makampani opanga kuwala, ma modulators ndi msika wofunikira wa lithiamu niobate.
