Abstract

In this letter, we propose a new optically based system to generate ultrawide-band (UWB) impulse signals. The system includes a Fabry-Pérot laser diode under gain-switched operation and an erbium-doped fiber amplifier used as an external-injection light source to generate optical pulses on the transmitter end, together with a PIN photodiode and a first-order microwave differentiator to convert optical pulses into electrical Gaussian monocycle pulses on the receiver front-end. The experimental and fast Fourier transform analytical results demonstrate that the proposed system can generate UWB impulse signals and provide several gigahertz bandwidths for future applications of high-bit-rate UWB wireless systems.
