Three-dimensional photonic crystals were fabricated using milli-meter-sized Si3N4 spheres. The transmittance spectra were measured, and the formation of photonic band gaps was observed. Moreover, a quantum well structure was fabricated using two kinds of photonic crystals. The transmittance spectra were measured for various well thicknesses, and numerous sharp peaks due to quantized states were observed in the high reflective frequency region of the barrier crystal. To discuss the symmetry of observed quantized states, the electrical field patterns in the well crystal were measured. Even and odd modes were observed alternately in each fine peaks. The results of analysis showed that the observed fine peaks were quantized states of a photonic band in a single quantum well.
