Abstract
A novel photonic microwave discrete-time finite-impulse response filter is created by spectrally slicing a supercontinuum source, generated from a mode-locked laser. We experimentally demonstrate a four-tap filter with a 28.16 dB extinction ratio. Comparison between measured and predicted magnitude responses shows an excellent match in the performance of the notch filter across the entire bandwidth. The small amount of individual deviation points from the predicted response shows the stability of the amplitude fluctuations between each of the individual, spectral sliced filter taps.
