Abstract
A thin film optical switch includes a layer of photosensitive material that extends laterally with first and second electrodes are spaced apart laterally from one another along the layer of photo sensitive material. The first and second electrodes contact the photo sensitive material at first and second junctions, respectively. At least one field plate is electrically insulated from the photo sensitive material and extends laterally along the layer of photo sensitive material over the first or the second junction. The field plate is electrically connected to the first electrode or the second electrode.
