Two photonic crystals have been prepared based on polymer opal-like films. Both polymer and semiconductor structures demonstrate similar photonic behavior. The width and dispersion of the stop-band has been greatly improved by decreasing the the filling factor of a high RI component and increasing the RIC. An antenna like effect the focusing of emission from incomplete photonic crystals has been observed and explained as the result of specific dispersion of the electromagnetic waves in the frequency range of PBG.
