Axially Frozen Modes in Finite Anisotropic Photonic Crystals

摘要

A comprehensive study of the oblique frozen modes in a finite one-dimensionalanisotropic photonic crystal is presented. The most attractive property of these waves is near-zeroaxial group velocity in conjunction with small reflection from the lattice interface. We use acharacteristic matrix analysis to describe both monochromatic wave and pulse propagation in onedimensionalanisotropic photonic crystal of finite length. Using a layered structure consisting of airand an example of a suitable material, SbSI, we demonstrate the slow down factor, intensityenhancement, bandwidth, and transmission coefficient of axially frozen modes.
