Fabrication of photonic crystal-hased ceramic materials is an important developing application. In this paper, recent researches about the fabrication and the application of ceramic photonic crystals in the frequency range from microwave to visible light of ceramic-based photonic crystals are reviewed. We focus on the tunable band-gap and spontaneous emission of ceramic photonic crystals caused by the various electric/optical properties of functional ceramics. Because ceramic photonic crystals have many advantages such as a high refractive index and extensive functions, and they can be fabricated by many different methods, they have great potential for a variety of applications; they can be used as optical switches based on the electro-optic effect and optical nonlinearity for communication application and as directional emissive light sources based on anisotropic light emission for display applications.
