A three-port optical circulator of W-format based on 2D photonic crystal is presented. This circulator is more compact as compared to the known one of the traditional Y-format. The W-circulator does not have rotational symmetry. As a consequence, the frequency responses for different port excitation are slightly different, as it is shown by symmetry analysis and by numerical simulations.
提出了一种基于二维光子晶体的 W 格式三端口光环形器。与传统 Y 格式已知的环形器相比，这种环形器更加紧凑。W 环形器没有旋转对称性。因此，不同端口激励的频率响应略有不同，这可以通过对称分析和数值模拟来证明。
