Abstract:

We report measurements of the diffraction pattern of a two-dimensional photonic quasicrystal structure and use of the set of plane-waves defined by the diffraction pattern as the basis of a theoretical approach to calculate the photonic band structure of the system. An important feature of the model is that it retains the essence of the rotational and inflational properties of the quasicrystal at all levels of approximation properties lost in approximate models which artificially introduce elements of periodicity. The calculated density of modes of the quasicrystals is found to display a weakly depleted region analogous to the band gap that occurs in a periodic system.
