Dense three-dimensional microphotonic crystals of SiO(2)-Al(2)O(3) ceramics were fabricated using microstereolithography and successive sintering process. The forming dimensional tolerance for a 50 vol% ceramic paste is 10 mu m and sintering shrinkage is around 12%. Diamond-type photonic crystals with lattice constants of 500 and 125 mu m were formed and sintered successfully. The band gaps of the samples were measured and compared with the theoretically calculated band diagram.
