Abstract

Two new circuit structures which exploit the properties of the fast opening GaAs photoconductive semiconductor switch are described. These new circuit structures, series current charged transmission lines, and dual of the Blumlein line, offer increased power output over our previous current charged transmission line circuit structure. In addition, the electrical and optical response of the poly-ZnSe switch under high applied electrical fields has been further investigated. Non-linear behavior is observed in the poly-ZnSe switch under high fields both experimentally and in numerical simulation. This type of non-linear behavior may be useful in high power opening switch applications as predicted by numerical simulation.
