The Multi-Channel Filter Based on Photonic Crystal with Circular Resonant Cavity

Abstract:

A photonic crystal model with circular resonant cavity is reported in order to achieve high efficiency and multi-channel filtration. Design a multi-channel filter based on its transmission properties. The distributions of the light energy of different wavelengths are given. As a result, the photonic crystal with circular resonant cavity has output efficiency of 75.5%99% and 100% when the wavelength is 1447nm1535nm and 1628nm. As the dielectric constant increases, the output wavelengths change. So, we can use this method to adjust the output wavelengths. Meanwhile, when the centre wavelength is 1447nm and 1535nm the multi-channel filter can output in different directions.
