Abstract
In the present paper, we have studied a two-dimensional photonic crystal structure of square lattice as channel drop filter application. Photonic crystal structure of square lattice was constructed with circular rods are embedded in air medium. The channel drop filter was designed with a point defect cavity nearby a waveguide, which constructed by removing a single row of rods near cavity. The cavity was designed by removing a number of rods, which characterized with dimension of the cavity. The transmission spectra were analyzed for the channel drop filter with the dimension of the cavity.
