In this paper, we propose a new design of two dimensional photonic crystal ring resonator (2D-PCRR) based channel drop filter (CDF). Through the two-dimensional (2D) finite-difference time-domain (FDTD) method with perfectly matched layers (PMLs) absorbing boundary conditions in triangular lattice photonic crystal (PC) silicon rods, 100% backward dropping efficiency with the quality factor of more than 1385 can be achieved at the optical communication window while the resonant wavelength is 1550 nm. Moreover, the effects of changing the dielectric constant of silicon rods as well as radius of whole rods are discussed and conclusions are reached. Based on the proposed component, a splitting operation with equal backward drop efficiencies and a quality factor of 2040 across all channels can be obtained. The proposed device has appropriate performances and could be used in the future photonic applications..
