Electric field measurements associated with second harmonic generation in thin film waveguides

We investigate the process by which induced static electric fields are produced in waveguide materials during SHG. Most of the models for the production of these fields rely on a photoionization process within the waveguide which has a preferential photoejection direction, i.e., a net current flow. Our work models the current that produces the static electric field and measures the electric fields outside the waveguide surface that are produced by this internal current flow
