Abstract :
We propose and experimentally demonstrate a reflective semiconductor optical amplifier (RSOA)-based Mach-Zehnder interferometer structure for generating high-order ultrawideband (UWB) signals. First, low-order UWB signals are generated by controlling the bias current of the RSOA. To convert the generated low-order UWB signals to high-order UWB signals, the polarization overlaying technique is used in an interferometer structure. The generated high-order UWB signals well satisfy Federal Communications Commission spectral regulations, and the interference with GPS band at 1.57542 GHz is suppressed.
