Abstract: We present an optical characterization of photonic glasses, composed of randomly arranged, monodisperse dielectric spheres packed at high filling fractions. We provide a detailed optical study of the resonant behavior of diffuse light transport through such systems. By means of independent static and dynamic measurements, we show resonances in the transport mean free path, diffusion constant, and also energy velocity of light. We also show that the main transport parameters can be controlled by varying the sphere diameter.
