Abstract

A photo-EMF detector for the collection of photons includes a substrate formed of a photorefractive semiconductor and a plurality of interlaced electrode pairs disposed over the substrate. Each electrode pair includes two parallel electrodes defining an active area therebetween for the collection of photons. One electrode of each pair is disposed between an adjacent pair of electrodes and proximate one electrode of the adjacent pair, light from striking a substrate surface between proximate electrodes and outputs from each of the plurality of interlaced electrode pairs are collected.
