Paper Abstract

Two devices based on picosecond photoconductivity are reported. One is a germanium on sapphire device with a response time (FWHM) faster than 50 ps and a sensitivity in excess of 0.1 ma/mW, and is suitable for use when ultra-high speed gating of electrical signal is required. The other is an optically triggered GaAs transferred-electron device that generates oscillation bursts of controllable duration and frequency over the ranges of 1.5 to 4.0 nsec and 6.7 to 10.5 GHz, respectively.
