Abstract :
We proposed and experimentally demonstrated two approaches to tunable photonic Ultra-wideband (UWB) signal generation based on nonlinear dynamics of the semiconductor laser. 1) UWB pulse generation based on chaotic dynamic of the optical feedback laser diode; 2) UWB pulse generation based on period-one oscillation of the optical injected laser diode. Both of the methods are convenient to adjust and control the spectrum characteristics of the UWB signals without utilizing high-speed electrical devices.
