Abstract
Heterogeneous 3-dimensional photonic crystals have been prepared by sandwiching self-assembled opal films and forced-assembled Langmuir-Blodgett colloidal crystal films. Strong transformation of the transmission spectra of the light traversing such hetero-crystals has been observed and interpreted in terms of the mismatch between eigenmodes of these photonic crystals and subsequent strong scattering at the interface between these crystals. Direct measurements of the spectra of forward scattered light have confirmed the peculiar character of the light scattering at the photonic crystal interface.
