## Abstract A continuously tunable incoherent microwave photonic filter employing a tunable Mach‐Zehnder interferometer (MZI) as the slicing filter is studied. By incorporating the optical variable delay line (OVDL), the frequency spacing of the MZI can be tuned continuously, which in turn makes th
