Abstract
AbstractMicrowave photonic filters have the advantages of wide tunability, low loss, and ease of reconfiguration. In this article, we propose a simple and cost‐efficient technique for the implementation of microwave photonic filter through simulations. This technique for the implementation of microwave photonic filter is employing a multiwavelength source and dispersive fiber. The multiwavelengths have been generated by employing optical carrier suppression based modulation. It has been shown that the free spectral range (FSR) of the filter may be tuned from 4.26 to 3.55 GHz by simply varying the frequency of the RF sinusoidal signal being used for modulation from 25 to 30 GHz, respectively. Furthermore, the bandwidth of the filter may be tuned by varying the number of filter taps.
