Abstract

In this study, the photonic band structure of two-dimensional photonic crystals with square and honeycomb lattices consisting of air holes in the Kerr nonlinear material background has been investigated. We assumed that the holes with different geometrical shapes are filled with plasma. The numerical results based on the finite difference time method show that most of the designed structures represent a complete photonic bandgap with noticeable width at optimum values of structural parameters for low-intensity incident waves, in which the width can be changed through varying the incident light intensity. The calculations show that when the shape of the plasmafilled holes is the same as the shape of the unit cell of the structures, the most change in the total photonic bandgap is visible in the frequency range as , ,,0 / 03(, c / a) the light intensity of the incident light changes. Furthermore, the maximum width of the photonic gap in these structures was reached , ,= 0. 0711(, c / a), which has increased approximately 0. 015(, c / a) in comparison with similar previously studied structures. The obtained result can be used for designing tunable optical devices.
