Abstract
The present work is devoted to simulation of photonic and magnetophotonic bandgap structures/crystals intended for various applications, particularly in the telecommunications in the GHz, THz to optical frequency bands (as waveguides, beam-guides, filters etc). The results of experimental and theoretical study of several types of 1 D photonic crystals are discussed. Structures under study are presented by periodical multilayered systems formed with: 1st type--ferrite/quartz and 2nd type--quartz/teflon/thin-film-bismuth and ruby/teflon/thin-film-copper. Theoretical predictions are fulfilled for a wide frequency band. The experimental verification of these the modeling results was performed in the EHF band (20-40 GHz). The possibility to control the shape of frequency stop-band zones has been modeled by using magnetically sensitive thin films forming the periodical structure of the 2nd type. It was demonstrated that the shape of the stop bands of the given magnetophotonic structure can be changed effectively by applying a magnetic field not exceeding 100 Oe. Various promising applications of these structures such as tunable extra high frequency and optical passive devices are discussed.
