We present a 32 channel indium phosphide integrated pulse shaper with 25 GHz spacing, where each is equipped semiconductor optical amplifier allowing for programmable line-by-line gain control submicrosecond reconfigurability. critically test the by using it in comb-based RF-photonic filtering experiments precise leveraged to synthesize high-fidelity RF filters which we reconfigure on microsecond time scale. Our on-chip shaping demonstration unmatched its combination of speed, fidelity, and flexibility, will likely open new avenues field advanced broadband signal generation processing.
