Abstract

This article describes a photoconductive resonant cavity in which a transmission line cavity, defined by impedance discontinuities, has a cavity length matched to the repetition rate of an exciting optical source, a semiconductor diode, for instance, which photoconductively produces picosecond electrical pulses at a particular point on the line. The intracavity signal is much larger than in the non-resonant case and the output is also larger. The generation of picosecond electrical pulses using photoconductive gaps excited by ultrashort light pulses [1] has become a standard technique. Various geometries have been used but none employing resonant structures.
