Opening up complete photonic bandgaps by tuning the orientation of birefringent dielectric spheres in three-dimensional photonic crystals

摘要

By using a multiple-scattering method, we study theoretically the photonic band structures of three-dimensional (3D) photonic crystals consisting of birefringent dielectric spheres. Our results demonstrate the possibility of opening up complete photonic bandgaps in 3D simple lattice photonic systems by changing the orientation of the extraordinary axis of the birefringent spheres.
