Conversional Light Reflectance from the Surface of Globular Photonic Crystals

The results of studies of laws of electromagnetic-radiation reflection from the surface of the globular photonic crystals are presented. Theoretical analysis was performed for the one-dimensional model of photonic crystal taking into account the presence of dielectric permeability resonances. Experimental studies were conducted using the fiber-optical technique. The regularities of conversional light reflection observed for photonic crystals that contain luminescing centers are established. The spectrum of conversional reflection excited by the quasi-monochromatic radiation is similar to the spectrum of selective reflection caused by the stop-band presence.
