Abstract

An approach to improve the filter characteristics of FIR optical delay line filter is presented. This scheme uses constrained least square algorithm to derive the optimum filter coefficients along with tuning of external phase shifter to reduce the overlap between adjacent pass bands. Based on this technique, a three port (1 × 3) lattice form FIR optical delay line filter is synthesized and compared with the existing results. The results of the filter designed is found to require only 18 stages, 50 dB stop band attenuation along with minimum attenuation of −24 dB in the overlap region. These values are significantly better compared to the literature reports available for similar filters.
