Abstract

In this work, we experimentally demonstrate a tunable microwave photonic filter working in 'Ku' frequency band (12-18 GHz). We followed three different schemes: double side band (double-SB), single side band (single-SB) and optical-carrier suppression (optical-CS) for our proposed photonic link. We also derived and numerically solved the transfer function for each case. Re-configurability (change in transfer function) of the filter is achieved by using laser switching (ON/OFF) and carefully windowing (using a higher order cosine window - the Blackman window) of the time samples in the range of 1-20 GHz. Moreover, we also investigate the amplitude comparison function (difference of power fading function) with the help of a vector network analyzer. Our experimental and simulation investigations are in good agreement with the theoretical analysis.
