Analysis of the microstructured eutectic Tb3Sc2Al3O12-TbScO3 photonic crystal properties

Abstract

In this paper, a numerical analysis of self-organized microstructured dielectric eutectic photonic crystal properties is presented. In particular, we study the terbium-scandium-aluminum garne-terbium-scandium perovskite structure Tb3Sc2Al3O12-TbScO3, grown by the micro-pulling down method. The self-organized dielectric microstructure is made of perovskite fibers embedded in a garnet phase matrix. In general, we analyzed the distribution of the electromagnetic field in the investigated periodic structures and the existence of a photonic band gap of such photonic crystals as a function of eutectic geometric parameters. Investigated structures do not reveal a wide photonic band gap, because of the low contrast of the refractive indices of individual phases. © 2011 Photonics Society of Poland.
