Abstract

We propose a new type of pass-band filter, in this case designed to
operate in the terahertz frequency regime, possessing two separate
pass-bands utilizing the distinction between positive and negative
refraction in a photonic crystal prism. The prism is formed from a
two-dimensional hexagonal arrangement of metallic rods. In order to
understand the operation of the filter we both consider the photonic
bandstructure of the associated infinite photonic structure and carry
out simulations of the refraction properties of the prism using
finite-difference time-domain software. (C) 2008 Optical Society of
