Abstract: Mono-dispersed colloidal spheres could be self-assembled into face-centered cubic (FCC, lattice period constant is a) structured three-dimensional photonic crystal materials, furthermore, the photonic crystal of colloidal spheres could be used as a template for filling in with high refractive index optical material, then remove the colloidal spheres to obtain inversed-Opal structured photonic crystal material with high refractive index difference for integrated optical devices. In the present work, in order to know the light propagation in this kind of material, simulation study with the finite difference time domain method (FDTD) was carried out to understand different wavelength light-beam propagations in this kind of photonic crystal, as well as in straight-line and L-shape line defects. Simulation results indicated that the band-gap region located between a/λ= 0.45 to 0.55, and the transmission coefficients for light-beam in straight-line and L-shape line defects in this photonic crystal reached up to~65% and ~72%, respectively.
