摘　　要：研究以GaAs为背景介质周期性排列的椭圆孔柱构成的长方晶格光子晶体,发现在优化光子晶体几何参数的基础上,通过调控椭圆孔柱的相对介电常数可以使高频区域的能带从完全光子带隙向零带隙转变.In this paper we designed a two-dimensional photonic cystal with a rectangular lattice of elliptic cylinders in the GaAs backgroud material. By manipulating dielectric of elliptic cylinders, one can obtain the controllable band gap structure. It is shown that tunable band gap in the high region of normalized frequency could be achieved by choosing the specific D-value of dielectric.
