Abstract :
We propose and characterize varying the tap-phases of the recently introduced complex-coefficient tunable conversion/dispersion based FIR filter by fine tuning of pump lasers. Full tap-phase tuning (- π to π) is achieved by detuning the frequency of laser pumps by <;10GHz, with close agreement to the theory.
