Abstract :
A photonic implementation of a reconfigurable microwave transversal filter is proposed. The implementation allows the filter taps to be both positive and negative. This allows for greater flexibility in the design of the filter so that bandpass and lowpass filters with flatter passbands could be realised. A four-tap version of the filter is demonstrated.
