摘要：

Photonic crystal based ring resonators are promising structures used for designing optical filters suitable for optical communication networks. In this work we use an H-shaped resonant ring for designing an optical filter. The proposed filter consists of two upper and lower waveguides coupled through an H-shaped resonator which is designed for coupling of an identical wavelength from upper waveguide to the lower one. We use numerical methods such as plane wave expansion and finite difference time domain for performing our simulations and studying the optical properties of the proposed structure. The transmission efficiency and quality factor of our filter is about 100% and 221 relatively. (C) 2015 Elsevier GmbH. All rights reserved.
