A new photonic crystal ring resonator (PCRR) configuration is provided based on two-dimensional (2D) square lattice photonic crystal (PC) silicon rods. The ring is formed by removing the line defect along M direction instead of conventional ΓX direction. Its spectral information including transmission intensity, dropped efficiency and quality factor affected by different physical parameters and the cascaded engineering including parallel and serial configurations are numerically analyzed with 2D finite-difference time-domain (FDTD) technique. The spectral quality factor of more than 830 and dropped efficiency of 90% at 1550 nm channel can be obtained with a less than 2.2 μm ring radius.
