ʻIke ʻia ʻo Lithium niobate ma ke ʻano he silika optical. Aia kekahi ʻōlelo ʻo "lithium niobate ke kamaʻilio optical he aha ke silika i semiconductors." ʻO ke koʻikoʻi o ke silika i ka hoʻololi uila, no laila he aha ka manaʻo o ka ʻoihana e pili ana i nā mea lithium niobate?
ʻIke ʻia ʻo Lithium niobate (LiNbO3) ma ke ʻano he "optical silicon" ma ka ʻoihana. Ma waho aʻe o nā pono kūlohelohe e like me ke kūpaʻa kino a me ke kemika, ka puka aniani ākea ākea (0.4m ~ 5m), a me ka coefficient electro-optical nui (33 = 27 pm / V), ʻo ka lithium niobate kekahi ʻano aniani me ka nui o ka maka. kumu waiwai a me ke kumu kūʻai haʻahaʻa. Hoʻohana nui ia i nā kānana hana kiʻekiʻe, nā mea electro-optical, holographic storage, 3D holographic display, nonlinear optical device, optical quantum communication a pēlā aku. Ma ke kahua o ka kamaʻilio optical, ʻo ka lithium niobate ka mea nui i ka hana o ka modulation māmā, a ua lilo ia i huahana nui i ka modulator electro-optical kiʻekiʻe o kēia manawa (Eo Modulator) makeke.
I kēia manawa, aia ʻekolu mau ʻenehana nui no ka hoʻololi ʻana i ka māmā i ka ʻoihana: electro-optical modulators (Eo Modulator) e pili ana i ke kukui silika, indium phosphide a melithium niobatenā paepae waiwai. Hoʻohana nui ʻia ʻo Silicon optical modulator i nā modules transceiver communication data pōkole, hoʻohana nui ʻia ka indium phosphide modulator i nā modula transceiver network a me ka lōʻihi, a me ka lithium niobate electro-optical modulator (Eo Modulator) i hoʻohana nui ʻia i loko. ka launa pū ʻana o ka iwi kuamoʻo lōʻihi a me nā kikowaena ʻikepili ultra-kiʻekiʻe-kiʻekiʻe. Ma waena o ʻekolu mau ultra-high speed modulator material platforms, ʻo ke kiʻi ʻoniʻoni ʻoniʻoni lithium niobate modulator i puka mai i nā makahiki i hala iho nei he pono bandwidth ʻaʻole hiki ke hoʻohālikelike ʻia nā mea ʻē aʻe.
ʻO ka Lithium niobate kahi ʻano mea ʻano inorganic, formula chemicalLiNbO3, he aniani maikaʻi ʻole, ferroelectric crystal, polarized lithium niobate crystal me ka piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric a me nā waiwai ʻē aʻe o ka mea, i ka manawa like me ka hopena photorefractive. ʻO ka kristal Lithium niobate kekahi o nā mea hou i hoʻohana nui ʻia, he mea hoʻololi piezoelectric maikaʻi, mea ferroelectric, electro-optical material, lithium niobate ma ke ʻano he electro-optical material i ke kamaʻilio optical e pāʻani ana i ka modulation māmā.
ʻO ka mea lithium niobate, i kapa ʻia ʻo "optical silicon", hoʻohana i ke kaʻina micro-nano hou loa e mahu i ka papa silicon dioxide (SiO2) ma luna o ka substrate silicon, e hoʻopaʻa i ka substrate lithium niobate i ka wela kiʻekiʻe e kūkulu i kahi ʻāpana cleavage, a hope ʻili. mai ke kiʻi lithium niobate. ʻO ke kiʻi ʻoniʻoni ʻoniʻoni lithium niobate modulator i hoʻomākaukau ʻia nā mea maikaʻi o ka hana kiʻekiʻe, ke kumukūʻai haʻahaʻa, ka liʻiliʻi, ka hana nui, a me ka hoʻohālikelike ʻana me ka ʻenehana CMOS, a he hopena hoʻokūkū no ka interconnection optical kiʻekiʻe i ka wā e hiki mai ana.
Inā kapa ʻia ke kikowaena o ka uila uila ma muli o ka mea silika i hiki ai, a laila hiki ke ʻike ʻia ke kiʻi photonics i ka lithium niobate, i kapa ʻia ʻo "optical silicon" lithium niobate he mea ʻike ʻole ʻia e hui pū i nā hopena photorefractive, nonlinear. nā hopena, nā hopena electro-optical, nā hopena acousto-optical, nā hopena piezoelectric a me nā hopena wela. Hiki ke hoʻomalu ʻia ka nui o kāna mau waiwai e ka haku mele, element doping, valence state control a me nā mea ʻē aʻe. Hoʻohana nui ʻia ia e hoʻomākaukau i ke alakaʻi nalu optical, hoʻololi optical, piezoelectric modulator,electro-optical modulator, ka lua harmonic generator, laser frequency multiplier a me nā huahana ʻē aʻe. I ka ʻoihana kamaʻilio optical, ʻo nā modulators kahi mākeke noi nui no ka lithium niobate.
