Abstract.

Calculations for the relative width (Dw /w₀) as a function of refractive index and relative radius of the photonic band gap for the fcc closed packed 3-D dielectric microstructure are reported and comparison of experimental observations and theoretical predictions are given. This work is useful for the understanding of photonic crystals and occurrence of the photonic band gap.

Keywords:  Photonic band gap; photonic crystal; dielectric microstructure.
