Abstract
A nonlocal nonlinearity results when optically excited carriers move within the internal electric fields of depletion regions, causing field-dependent changes in absorption and/or refractive index. We review some recent experimental results and use these concepts in hetero-Schottky barriers and hetero-n-i-p-i structures. We show that extremely sensitive, rather large nonlinearities result.
