Paper Abstract

An all-optical realization of a two-tap complex-coefficient microwave photonic filter, working under incoherent mode, is proposed and demonstrated. The complex coefficient is realized by simply adjusting the bias voltage applied to the dual-electrode Mach–Zehnder modulator. The real coefficient is controlled by adjusting the power of the two taps. As a result, the frequency response of the filter can be continuously tuned, over a full free spectral range, without changing the shape of the filter.
