A novel approach to generating ultra-wideband (UWB) impulses based on a Mach–Zehnder modulator (MZM) and a Fabry–Pérot semiconductor optical amplifier (FP-SOA) is proposed and demonstrated. Both the carrier dynamic behavior of SOA and the feedback of FP cavity are exploited to generate a pair of polarity-reversed doublet-like impulses. Simulations and experiments are carried out to verify the UWB...
We propose and experimentally demonstrate a microwave photonic filter based on an electro-optic phase modulator (EOPM) and a Fabry–Pérot semiconductor optical amplifier (FP-SOA). A microwave photonic filter with a single passband between 0 and 40GHz is obtained. The center frequency, the −3dB bandwidth and the −30dB bandwidth of the microwave photonic filter are 18.3, 3.184 and 4.005GHz respectively...
