The commercialization of the lithium niobate on insulator provides birth for the emergence of large-high-quality lithium niobate photonic crystals. To be able to supply assistance into the investigation of lithium niobate photonic crystal equipment, modern development about fabrication, characterization, and applications of the thin-movie lithium niobate photonic crystal is reviewed. https://henryt357ojb2.blogsidea.com/profile
