2D honeycomb photonic crystal under applied magnetic fields

摘要

The band-structure properties of a photonic two-dimensional honeycomb lattice formed by cylindrical semiconductorshell rods with dielectric permitivities ε_1and ε_2,and embedded in a background with permitivity83,is studied by using an standard plane-wave expansion. The properties of bandgaps and density of states, considering dispersivedielectric responses, are investigated together with the possibility of fabricating systems with tunable photonic bandgaps,due to the Voigt magneto-optical effect, under the influence of an external magnetic field.
