Pulse Compression Photoconductive Switching Using Negative Differential Mobility

This work demonstrates a novel optoelectronic device with the potential for use as a high-frequency, high-power RF source or amplifier. The device is a gallium-arsenide coplanar waveguide with a small gap in the signal trace for optical illumination. A confined charge cloud is generated by illuminat...
