Abstract :
We present a programmable multi-tap microwave photonic phase filter operating over an ultra-wide bandwidth. Complex programmability of >;30 taps is achieved by optical line-by-line pulse shaping on a 10 GHz Gaussian optical frequency comb using a novel interferometric scheme. Through high-speed real-time measurements, we show programmable chirp control in the range ±0.6GHz ns.
