The photonic Wannier function approach to photonic crystal simulations: Status and perspectives

Photonic crystals represent a novel platform for the realization of integrated photonic circuits with numerous applications. This article reviews the present status of a computational approach dedicated to these systems that is based on photonic Wannier functions. The workings of the Wannier function approach are illustrated by way of selected examples. In addition, we discuss the advantages and limitations of this approach and sketch potential future developments. © 2011 Taylor & Francis
