Bandgap structure of optical Fibonacci lattices after light diffraction.

Kaliteevski, M.A. and Nikolaev, V.V. and Abram, R.A. and Brand, S. (2001) 'Bandgap structure of optical Fibonacci lattices after light diffraction.', Optics and spectroscopy., 91 (1). pp. 109-118.


The modification of the bandgap structure of optical Fibonacci lattices that arises from an increase in the system size is analyzed. It is found that there is a minimum critical size of the Fibonacci lattice necessary to form a photonic bandgap. The analysis of localized photonic modes of Fibonacci lattices shows that the removal of two layers of a lattice makes the lattice mirror-symmetric. The “method of oblique bands” is developed to analyze the bandgap structure of quasi-crystals. This method can also be applied to study two-and three-dimensional photonic and atomic quasi-crystals.
