Research of spectral characteristics for photonic crystals with fractal defects

Abstract

Optical properties of photonic crystals (PhCs) can be controlled by changing physical parameters of materials and geometry of structure elements. At the present time a special attention is put to study tunable PhCs. Practically, their possible applications are based on reconstruction in temperature, magnetic or light fields. On the other hand, the simplest way for making changes in spectral characteristics (coefficients of transmission and reflection) is putting local inhomogeneities in structure. Due to fractal objects' unique property of self-similarity, a particular interest is represented by PhCs with fractal defects. Within the present paper, temperature tunable two-dimensional PhC with fractal defects of two main types, notably Cantor-based and Peano curve-based are considered.
