Optoelectronic devices such as photoconductive switches have wide applications in electronic switching, waveform generation, optical detection, and broadband circuit characterization.  In this project, the students will characterize the ultrafast electrical transients produced by a special type of optoelectronic device based on numerical modelling and simulation using 2D/3D device simulation tools.  Various physical and device parameters influencing the generated electrical pulse will be investigated, from which the optimum design can be predicted.  Through the project, the students will learn state-of-the-art TCAD tools in optoelectronic device design and analysis.
