| Abstract: | The structure of 1×2 type photonic crystal power splitter with ring resonators is designed in a two-dimensional square-lattice dielectric-rod photonic-crystal structure, and it consists of one input and two outputs. Its electromagnetic wave transmission performance is investigated by using finite-difference time-domain method. The results show that the structure has a high transmission efficiency in the third communication window (wavelength 1 550 nm), and can split pass band electromagnetic waves equally. It is compact with low loss and design flexibility in propagation direction of electromagnetic waves. |
