The Relationship between Distances of Circular Photonic Crystals and Wavelength in Perpendicular Corner Propagation

Due to the period 3-D structure, photonic crystals would form photonic bandgap. They are more important and widely used in optical communication, energy and display regime. The relationship between distances of circular photonic crystals and wavelength in perpendicular corner propagation is investigated in this study. There are six types of propagation found in the results. With the maximum propagation efficiency, the relationship between distances of circular photonic crystals and wavelength is the curve of decay ripple wave like. It is found under different distances of photonic crystals, there are three types between the propagation efficiency and wavelength
