Abstract: In this paper, a method used to manufacture rapidly three-dimension photonic crystal
has been introduced. With stereolithography and gel casting, three-dimension photonic crystal
with diamond structure could be fabricated. The test of microwave frequency spectrum shows that,
bandgap of the photonic crystal obtained is between -, matching close with
that designed theoretically. Three-dimensional EBG structure is reconstructed with Micro-CT
shows that the internal structure is integrated, and linear density is uniform and stable. The
bining stereolithography and gel casting provides an efficient method to rapidly
manufacture three-dimension photonic cryst
