Eo Modulator Series: Chifukwa chiyani lithiamu niobate imatchedwa silicon optical

Lithium niobate imadziwikanso kuti silicon optical. Pali mawu akuti "lithium niobate ndikulankhulana ndi kuwala zomwe silicon ndi ma 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 pa zabwino zachilengedwe monga kukhazikika kwa thupi ndi mankhwala, zenera lowoneka bwino lowoneka bwino (0.4m ~ 5m), komanso ma electro-optical coefficient (33 = 27 pm/V), lithiamu niobate ndi mtundu wa kristalo wokhala ndi zinthu zambiri zopangira komanso 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 kuwala modulator zimagwiritsa ntchito yochepa osiyanasiyana deta kulankhula transceiver zigawo, indium phosphide modulator zimagwiritsa ntchito sing'anga-osiyanasiyana ndi yaitali osiyanasiyana kuwala kulankhula maukonde transceiver zigawo, ndi lithiamu niobate electro-kuwala modulator (Eo Modulator) zimagwiritsa ntchito patali siyana kulankhulana msana ndi 1G0b0-waverent network 1G0b0-waverent ultra-high-speed data centers. 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.

The lifiyamu niobate zakuthupi, lotchedwa "kupenya pakachitsulo", ntchito atsopano yaying'ono-nano ndondomeko nthunzi ndi pakachitsulo woipa (SiO2) wosanjikiza pa silicon gawo lapansi, zomangira lifiyamu niobate gawo lapansi pa kutentha kuti amange pamwamba cleavage, ndipo potsiriza peel pa lifiyamu niobate filimu. 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 pakatikati pa kusintha kwamagetsi amatchulidwa ndi zinthu za silicon zomwe zinapangitsa kuti zitheke, ndiye kuti kusintha kwa photonics kungayambike kuzinthu za lithiamu niobate, zomwe zimatchedwa "optical silicon" lithiamu niobate ndi chinthu chopanda utoto chomwe chimagwirizanitsa zotsatira za photorefractive, zotsatira zopanda malire, electro-optical effects, zotsatira za acousto-optical, piezoelectric zotsatira ndi zotsatira za piezoelectric. 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.
