E mōhiotia ana hoki te lithium niobate ko te silicon whatu. E kīia ana "ko te lithium niobate ki te whakawhitiwhiti whatu, pērā i te silicon ki ngā semiconductors." Ko te hiranga o te silicon i roto i te hurihanga hikohiko, nō reira he aha te mea e tino tumanako ai te umanga ki ngā rauemi lithium niobate?
E mōhiotia ana te Lithium niobate (LiNbO3) ko te "silicon whatu" i roto i te umanga. Haunga ngā painga taiao pēnei i te pumau ā-tinana me te matū pai, te matapihi whānui mārama whatu (0.4m ~ 5m), me te tauwehenga hiko-whatu nui (33 = 27 pm/V), he momo tioata anō hoki te lithium niobate he nui ngā rauemi mata me te utu iti. He whānui te whakamahinga i roto i ngā tātari mahi teitei, ngā taputapu hiko-whatu, te rokiroki holographic, te whakaaturanga holographic 3D, ngā taputapu whatu kore-raina, te whakawhitiwhiti ira whatu me ētahi atu. I roto i te mara o te whakawhitiwhiti whatu, ko te lithium niobate te nuinga o te mahi hei whakarerekē i te mārama, ā, kua noho hei hua matua i roto i te whakarerekētanga hiko-whatu tere-teitei o nāianei (...Kaiwhakahaere Eo) mākete.
I tēnei wā, e toru ngā hangarau matua mō te whakarerekētanga mārama i roto i te umanga: ngā whakarerekētanga hiko-whatu (Eo Modulator) i runga i te mārama silicon, te indium phosphide me telithium niobatengā tūāpapa rauemi. Ko te kaiwhakatikatika whatu silicon e whakamahia nuitia ana i roto i ngā kōwae whakawhiti raraunga tawhiti-poto, ko te kaiwhakatikatika indium phosphide e whakamahia nuitia ana i roto i ngā kōwae whakawhiti whatunga whakawhitiwhiti whatu tawhiti-waenga me tawhiti-roa, ā, ko te kaiwhakatikatika hiko-whatu lithium niobate (Eo Modulator) e whakamahia nuitia ana i roto i te whakawhitiwhiti whatunga tuara tawhiti-roa me ngā pokapū raraunga tere-tino-teitei 100/200Gbps ngaru-kotahi. I roto i ngā tūāpapa rauemi kaiwhakatikatika tere-tino-teitei e toru i runga ake nei, ko te kaiwhakatikatika lithium niobate kiriata angiangi kua puta ake i ngā tau tata nei he painga whānui kāore e taea e ētahi atu rauemi te whakataurite.
He momo matū kore-waro te lithium niobate, he tauira matūLiNbO3, he tioata kino, he tioata ferroelectric, he tioata lithium niobate polarized me ngā āhuatanga piezoelectric, ferroelectric, photoelectric, nonlinear optics, thermoelectric me ētahi atu āhuatanga o te rauemi, i te wā kotahi me te pānga photorefractive. Ko te tioata lithium niobate tētahi o ngā rauemi inorganic hou e whakamahia whānuitia ana, he rauemi whakawhiti pūngao piezoelectric pai, rauemi ferroelectric, rauemi electro-optical, lithium niobate hei rauemi electro-optical i roto i te whakawhitiwhiti whatu he mahi i roto i te whakarerekētanga mārama.
Ko te rauemi lithium niobate, e mōhiotia ana ko te "silicon optical", e whakamahi ana i te tukanga micro-nano hou hei whakamahana i te paparanga silicon dioxide (SiO2) i runga i te papa silicon, hei here i te papa lithium niobate i te pāmahana teitei hei hanga i te mata pakaru, ā, hei whakamutunga ka tihorea te kiriata lithium niobate. Ko te kiriata angiangi lithium niobate modulator kua whakaritea he pai te mahi, he iti te utu, he iti te rahi, he nui te hanga, me te hototahi ki te hangarau CMOS, ā, he otinga whakataetae mō te hononga whatu tere-tiketike a meake nei.
Mena ka tapaina te pokapū o te hurihanga hikohiko i muri i te rauemi silicon i taea ai, kāti ka taea te whai i te hurihanga photonics ki te rauemi lithium niobate, e mōhiotia ana ko te "silicon optical". Ko te lithium niobate he rauemi mārama kore tae e whakakotahi ana i ngā pānga photorefractive, ngā pānga kore-raina, ngā pānga electro-optical, ngā pānga acousto-optical, ngā pānga piezoelectric me ngā pānga wera. He maha o ōna āhuatanga ka taea te whakahaere mā te hanganga tioata, te tāpiri huānga, te whakahaere āhua valence me ētahi atu āhuatanga. He whānuitia te whakamahinga hei whakarite i te arataki ngaru whatu, te pana whatu, te modulator piezoelectric,kaiwhakarerekē hiko-whatu, te whakaputa hiko tuarua, te whakarea auau taiaho me ētahi atu hua. I roto i te umanga whakawhitiwhiti kōrero whatu, he mākete tono nui ngā whakarerekētanga mō te lithium niobate.
