• A single passband, photonic microwave finite impulse response filter, whose passband frequency can be dynamically tuned with a high frequency resolution, is experimentally demonstrated. A computer-controlled, differential group delay (DGD) device-based comb filter is used to produce flexible wavelength-spacing tunable, multi-wavelength filter taps with a sinusoidal and continuous spectral shape. An RF frequency tuning resolution as low as ${\sim}1.16$ MHz is demonstrated.
