Abstract : The central theme of our work at Ginzton is the development of new material and device technologies, along with novel techniques for characterization and measurement, that will allow ultra-high speed electronic and optical processing of information. The different work units of this proposal interconnect the physics and technology of linear and nonlinear optical materials and fibers with new measurement tools which provide unprecedented spatial and temporal resolution. The following paragraphs summarize each of these work units. Professor Bloom's work h as been concerned with developing laser techniques for obtaining both time and frequency domain measurements of high speed electrical circuits. His efforts have been concerned with both electrooptic voltage sampling in gallium arsenide and with real time charge sampling in silicon. Using these techniques Bloom and his students have demonstrated 2 p.s. time resolution, and circuits with response into the 100 GHs range. A particularly exciting achievement during this contract period was the development of the charge sensing technique in silicon. This concept has in turn allowed the development of a very simple silicon optical modulator with extraordinary potential.
