Abstract :
A new technique that can overcome the dominant dispersion-induced RF distortion in spectrum sliced photonic signal processors, is presented. It is based on the concept of the staircase optical delay line. Experimental results demonstrate the elimination of high frequency limitations in both tunable and multi-tap spectrum sliced microwave photonic filters.
