A monocycle Ultra-Wideband (UWB) pulse generator based on 2-tap microwave photonic filter with phase inversion is proposed. The microwave filter is fed by two lasers and uses phase inversion in a Mach-Zehnder modulator to generate negative coefficients. The proposed UWB pulse generator incorporates a variable delay line to compensate the effects of the chromatic dispersion over the generated UWB pulse...
In this paper, we present a complete and closed theoretical model and its subsequent practical verification for a special type of Mach-Zehnder electrooptical modulator with a 2times1 optical ports configuration (two optical inputs/one output). This device present special modulation features due to its own optical structure. Its employment for modulation of millimeter and microwave signals and their...
We present the theoretical analysis and experimental measurements of an all-optical novel configuration to implement a microwave photonic filter by combining a mode-locked fiber laser and a Mach-Zehnder structure in cascade to a 2times1 electro-optic modulator. The proposed structure shows a novel characteristic consisting on the RF filter being free from carrier suppression effect and thus not requiring...
