INVESTIGATION OF THE Q-FACTOR OF OPTICAL RESONATORS IN PHOTONIC CRYSTALS AND PRINCIPLES OF DESIGNING HIGHLY SELECTIVE FILTERS ON THEIR BASIS

摘要

Designs of optical resonators comprising a half-wavelength dielectric layer bounded from both ends by quarter-wavelength layers with permittivity higher or lower than that of the half-wavelength layer are investigated. Electrodynamic analysis demonstrates a significant increase in the Q-factor of the multilayered resonator in comparison with the conventional single-layer half-wavelength resonator. Principles of designing highly selective passband filters based on photonic crystal structures are considered.
