초록
Optical filtering characteristics of planar distributed feedback (DFB) guiding structures are evaluated by using an equivalent network based on the newly developed concept of Floquet’s theorem and bisection principle (Babinet’s theorem). Additionally, such optical parameters as Bragg condition and the reflectivity varied along with grating period are numerically calculated. The numerical results reveal that this method offers a simple and convenient algorithm to analyze the filtering and oscillating characteristics of DFB configurations as well as decreases dramatically the computational time.
