A makwaara Lithium niobate dị ka silicon ngwa anya. Enwere okwu na "lithium niobate bụ nkwurịta okwu anya ihe silicon bụ semiconductors." Mkpa silicon dị na mgbanwe elektrọnik, yabụ kedu ihe na-eme ka ụlọ ọrụ ahụ nwee nchekwube banyere ihe lithium niobate?
A maara Lithium niobate (LiNbO3) dị ka "Silicone ngwa anya" na ụlọ ọrụ ahụ. Na mgbakwunye na uru sitere n'okike dị ka ezigbo nkwụsi ike anụ ahụ na kemịkalụ, windo na-ahụ anya nke ọma (0.4m ~ 5m), yana nnukwu ọnụọgụ eletrọnịkị (33 = 27 pm / V), lithium niobate bụkwa ụdị kristal nwere nnukwu raw. isi mmalite ihe na ọnụ ala dị ala. A na-eji ya n'ọtụtụ ebe na nzacha arụmọrụ dị elu, ngwaọrụ electro-optical, nchekwa holographic, ihe ngosi holographic 3D, ngwa anya na-adịghị ahụ anya, nkwurịta okwu quantum na ihe ndị ọzọ. N'ihe gbasara nzikọrịta ozi anya, lithium niobate na-arụkarị ọrụ nke mgbanwe ọkụ, ma bụrụkwa ngwaahịa a na-ahụkarị na ngwa ngwa eletrọ-optical modulator ugbu a.Eo Modulator) ahịa.
Ka ọ dị ugbu a, e nwere teknụzụ isi atọ maka mgbanwe ọkụ na ụlọ ọrụ: electro-optical modulators (Eo Modulator) dabere na ọkụ silicon, indium phosphide nalithium niobateihe nyiwe. A na-ejikarị Silicon optical modulator eme ihe na modul transceiver nkwurịta okwu data dị mkpirikpi, indium phosphide modulator bụ nke a na-ejikarị eme ihe na ọkara-n'ogologo na ogologo oge transceiver network transceiver modul, na lithium niobate electro-optical modulator (Eo Modulator) bụ nke a na-ejikarị na ya. nkwurịta okwu na-ejikọta netwọk azụ ogologo ogologo yana otu ebili mmiri 100/200Gbps ultra-high-speed data center. N'ime usoro ihe eji eme ihe modulator atọ dị n'elu, ihe nkiri lithium niobate modulator dị mkpa nke pụtara n'afọ ndị na-adịbeghị anya nwere uru bandwidth nke ihe ndị ọzọ enweghị ike dakọtara.
Lithium niobate bụ ụdị ihe inorganic, usoro kemịkalLiNbO3, bụ kristal na-adịghị mma, kristal ferroelectric, kristal polarized lithium niobate crystal na piezoelectric, ferroelectric, photoelectric, optics na-adịghị ahụ anya, thermoelectric na ihe ndị ọzọ nke ihe ahụ, n'otu oge ahụ na-enwe mmetụta fotorefractive. Lithium niobate kristal bụ otu n'ime ihe ọhụrụ inorganic a na-ejikarị eme ihe, ọ bụ ihe dị mma piezoelectric ike mgbanwe ihe, ferroelectric ihe, electro-optical ihe, lithium niobate dị ka ihe electro-optical ihe na ngwa anya nkwurịta okwu na-ekere òkè na ìhè modulation.
Ngwongwo lithium niobate, nke a maara dị ka "sicon optical", na-eji usoro micro-nano kachasị ọhụrụ na-eme ka oyi akwa silicon dioxide (SiO2) dị na mkpụrụ silicon, jikọta mkpụrụ lithium niobate na okpomọkụ dị elu iji wuo ebe mgbawa, ma n'ikpeazụ bee. pụọ na fim lithium niobate. Ihe nkiri lithium niobate modulator a kwadebere nke ọma nwere uru nke arụmọrụ dị elu, ọnụ ala dị ala, obere nha, mmepụta oke, yana ndakọrịta na teknụzụ CMOS, yana ngwọta asọmpi maka njikọta ngwa anya dị elu n'ọdịnihu.
Ọ bụrụ na etiti nke mgbanwe elektrọn ka aha ya bụ ihe silicon nke mere ka o kwe omume, mgbe ahụ, mgbanwe photonics nwere ike ịpụta na ihe lithium niobate, nke a maara dị ka "sicon optical" lithium niobate bụ ihe na-enweghị agba nke na-ejikọta mmetụta fotorefractive, nke na-adịghị adị. mmetụta, electro-optical mmetụta, acousto-optical mmetụta, piezoelectric mmetụta na thermal mmetụta.
