Manipulation of One-Dimension Photonic Crystal Spectrum via Perforated Silicon Slab

Abstract

This paper describes the study of zone-spectra of one-dimension finite-element photonic crystal quartz/silicon in the millimetre waveband. The silicon elements of photonic crystal are performed as slabs with holes. The numerical and experimental investigations have demonstrated the possibility of using the effective medium approach for the silicon element of photonic crystal. The paper introduces a simple phenomenological formula for the calculation of effective permittivity of perforated silicon slab.

Method of measuring non-equilibrium carriers concentration and their lifetime in a semiconductor using the approach of a photonic crystal with a defect mode

“…For this reason the structures from dielectrics and ferrites are used [3]. The presence of semiconductor layers in PCs should make it possible to control spectral properties by using the external effects like temperature [4], illumination [5], and injection of inhomogeneities in a semiconductor layer [6]. It is necessary to use semiconductors to create light controllable PCs [7], because there is photoconductivity in the semiconductors.…”
