The photonic band structure of 3D ordered silica matrices was studied by optical transmission measurements. A decrease of the light attenuation length within the forbidden gap was observed after filling of the opal pores with CdS microcrystals. The parameters of a photonic lattice required for a depletion of the photonic density of states were estimated.
