Conformal Transformation Of Photonic Crystal Structures
PHOTONIC AND PHONONIC PROPERTIES OF ENGINEERED NANOSTRUCTURES III(2013)
摘要
In this paper we present an algorithm that maps a reference diffracting structure along an arbitrarily curved boundary. The proposed algorithm produces deformed photonic crystal lattice patches with minimal angular distortion of its unit cells, thus realizing a discrete quasi-conformal transformation of the dielectric map. We then investigate the field confinement characteristics of some curved waveguide devices realized by such structures.
