Dynamic chirped microwave photonic filter

摘要

A chirped single bandpass microwave photonic filter based on a broadband optical source, a Mach-Zehnder interferometer and a dispersive element is proposed. Special and unique features are shown such as the capacity of modifying the chirp in the passband using the dispersive element together in combination with the possibility of tunability and reconfigurability. The later features are achieved by means of a Mach-Zehnder interferometer and the power spectrum distribution of the optical source.
