Bandgap properties of low index contrast aperiodically ordered photonic quasicrystals
Gianluigi Zito, T. Priya Rose, Emiliano Di Gennaro +3
We numerically analyze, using Finite Difference Time Domain simulations, the bandgap properties of photonic quasicrystals with a low index contrast. We compared 8-, 10- and 12-fold…

Hypergeometric-Gaussian Modes
Ebrahim Karimi, Gianluigi Zito, Bruno Piccirillo +2
We studied a novel family of paraxial laser beams forming an overcomplete yet nonorthogonal set of modes. These modes have a singular phase profile and are eigenfunctions of the ph…
