Abstract
We report further investigations of the surface electric fields present between the contacts ofan optically controlled silicon switch. The Kerr electro-optic effect and a phase sensitive interferometric analyzer is used to measure the surface fields when a pulsed high voltage is applied across the contacts. The experimental arrangement has a temporal resolution of 100 nanoseconds and a spatial resolution of 50 microns. The experimental results show preferential field enhancement near the anode and the surface electric fields are nonuniform in space and time. The temporal non-uniformity is more pronounced at higher electric fields.
