A novel approach to generate ultra-wideband (UWB) monocycle or doublet pulse using cross-gain modulation in fiber optical parametric amplifier is demonstrated in a single experimental setup. The high-speed optical parametric process realizes the signal amplification, idler generation, and pump depletion simultaneously within femtosecond response time in the highly nonlinear fiber. After the combination...
We proposed and demonstrated a novel approach to implement a photonic microwave filter by using cross-gain modulation in fiber optical parametric amplifier (OPA). Two-tap notch filter and four-tap bandpass filter were successfully demonstrated.
