The commercialization with the lithium niobate on insulator provides beginning into the emergence of high-excellent lithium niobate photonic crystals. In an effort to deliver steerage towards the investigate of lithium niobate photonic crystal units, current progress about fabrication, characterization, and apps of the thin-film lithium niobate photonic crystal is reviewed. https://hectorrsqqp.blogitright.com/32570503/an-unbiased-view-of-lithium-niobate-crystal
