Reconfigurable Photonic Microwave Filter based on Four-Wave Mixing

A simple technique to reshape the response of tapped delay line photonic microwave filters is demonstrated. The technique is based on the generation and control of a set of optical carriers by means of four-wave mixing. Experimental results show reconfiguration from 2 to 5 taps with uniform and apodized amplitude distributions. © 2009-2012 IEEE.Vidal Rodriguez, B.; Palací López, J.; Capmany Francoy, J. (2012).
