Abstract

We have self-assembled photonic crystal with a multistack structure using same size of spheres but from materials with different refractive indices. Al2 O3, ZnO, and TiO2 are infiltrated into opal templates by atomic layer deposition. Stacking multiple inverse opal structures with different refractive index contrasts broadens the reflection bands dramatically. Numerical simulations with plane wave expansion method show good agreement with experimental results.
