The insertion of high dielectric rods in the low dielectric region of photonics crystal enables the optical properties to be reconfigurable. We show that for a square array of holes, the inserted rods define the waveguide region, wavelength of operation and functionality of the photonic crystal device (directional coupler presented). Also are examined the modification of the resonator state’s wavelength and field profile when rods are introduced in the central region of two types of quasi-crystals. Based on these results more elaborate reconfigurable devices can be derived.
