Research Overview:
The activities within the Ultrafast Technology and Terahertz Optoelectronics Laboratory may best be described as a marriage of optics and electronics.  Here, ultrafast laser pulses are used with novel optoelectronic devices to generate and measure electrical pulses of the shortest possible durations.  These signals, which have bandwidths in excess of one terahertz (1012 Hz), can be guided and used to investigate the operation of new electrical interconnects or integrated circuits, or they can be formed into radiating "terahertz beams" and used for spectroscopic applications.
