Paper Abstract

We propose and demonstrate a novel approach generating ultrawideband (UWB) monocycle pulses using cross phase modulation (XPM) of the semiconductor optical amplifier (SOA). A pair of polarity-reversed UWB monocycle pulses is achieved by locating the probe carrier at the positive and negative linear slopes of the filter. We achieve different UWB spectrum width by 25ps- and 50ps-width Gauss pulse injection. The generated monocycle pulses can be controlled by either optical Gauss pulse or both injections, which function as logic OR-monocycle. It has potential applications in UWB-over-fiber communications.
