Abstract

Summary from only given. We study the energy flow inside an inverted opaline photonic crystal for the frequencies near the Bragg stopband. We present a theoretical and experimental study of a far field intensity of the spontaneous emission of dye molecules randomly distributed and orientated inside the crystal. Due to the random orientation of molecules, such an incoherent light source leads to the emission of photons with a continuum of different wave-vectors directions.
