In this paper, we investigate the variation of band gap width in a ternary 1D photonic crystal with a left- -handed layer versus variation of thicknesses and refractive index of second layers. We study these variations in two states, normal and oblique incidents for both TE and TM polarizations. We observe that the variations of band gap width versus thickness of layers are sensitive to the refractive index of second layers. For oblique incident both of variations are shifted towards the large/small frequencies by increasing the incident angles in TE/TM polarization, respectively.

    Based on the photon localization and the photonic bandgap characteristics of photonic crystals (PCs), one-dimensional (1D) ring mirror-defect photonic crystal structure is proposed. Due to the introduction of mirror structure, a defect cavity is formed in the center of the photonic crystal, and...

    We report on the design and the experimental evidence of a flat graded index photonic crystal lens. The gradient has been designed so that the flat slab focuses a plane wave and so that it converts the wave issued from a point source into a plane wave. This graded-index photonic crystal lens...

    We analyse inhibition of emission in a 2.5D photonic structures made up of a photonic crystal (PhC) and Bragg mirrors using Finite Differences Time Domaine (FDTD) simulations. A comparison is made between an isolated PhC membrane and the same PhC suspended onto a Bragg mirror or sandwiched...
