Abstract
In the present paper a novel structure for optical Channel drop Filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite difference time domain (FDTD) method. The transmission efficiency of 100%, quality factor of 2583 and bandwidth of 0.6 are achieved at a wavelength near to 1550 nm which proved this filter is usable and suitable for optical communication applications.
