Abstract

Photonics crystal (PhC)is the material in which the refractive index changes periodically and the PhC has a band structure and location mode

this structure can control light.In order to study two-dimensional PhC complete band gap

in this paper

plane wave expansion method was employed to simulate four types of two-dimensional PhC. We study the relationship between the complete bandgap and the variation of column radius

with a fixed lattice constant. We found that hexagonal lattice PhC air holes complete band gap appears in the

=0.42~0.50 m range

complete band gap width does not increase with the air column radiu

but there is a maximum width. The maximum band gap width is

=0.08(

).When air column radiu

=0.47~0.50 m

square lattice PhC exists complete bandgap

the band gap width

=0.02(

).And complete band gap center frequency increases with

. Results indicate that for hexagonal and square GaAs columnar PhC there is no complete band gap.
