Abstract
Porous synthetic opal possessing a three-dimensional photonic band structur e of semimetallic type was impregnated with polycrystalline CdS. The photon ic stop band in (111) direction was examined by means of photoreflection te chnique. Under cw laser excitation of semiconductor inclusions the reflecta nce of the system changes indicating a modification of photonic band struct ure. A possible mechanism is discussed. Numerical simulations within the fr amework of quasicrystalline approximation are given.
