Paper Abstract

The edge-triggered generation of baseband ultra-wideband (UWB) monocycle pulse using a dual-parallel Mach-Zehnder modulator is proposed and experimentally demonstrated. By setting three biases of the modulator at maximum, minimum and linear transmission points respectively, a monocycle UWB pulse sequence with the fractional bandwidth of ~ 155% is generated. The pulse sequence is differential encoded and the pulse bandwidth is determined by the transition time of the drive edge due to the nonlinear biases of the modulator. Furthermore, by using a basic digital signal processing (DSP) algorithm to calculate the bit error rate (BER), the transmission performance over a 25km-fiber is studied.
