Optoelectronic waveforms generation: PCSS characterization and genetic algorithm

This paper proposes a contribution to optoelectronic ultra-wideband transient waveforms generation. It describes a genetic algorithm (GA) development, a Photoconductive Semiconductor Switch (PCSS) characterization and optimization modeling. The genetic algorithm enables generation of arbitrary transient waveforms from specific spectral conditions. Experimental measurements have been carried out with an optoelectronic bench which generates high-voltage pulses (few kV peak). Measurements lead to an Agilent Advance Design System (ADS) modeling predicting PCSS response to an optical impulsion at 1064nm.
