Abstract :
We design a new type of channel add/drop filter based on photonic crystal ring resonator (PCRR). The dropping efficiency and quality factor of the new type filter are simulated by finite-difference time-domain (FDTD) method. Comparing to the traditional quasi-square-ring PCRR, the new type filter has higher quality factor, and close to 100% dropping efficiency.
