The origin and nature of nonlinear optical effects in organic and polymeric materials is discussed. Approaches to the applications of these nonlinear optical effects in prototypical devices is explored. In glancing through a flat windowpane we immediately confront lights interaction with glass, but ignore it. We assume that the worlds image is not perceptibly altered when light passes through the glass. Yet glass does play tricks with light a penny viewed through a variety of lenses may appear the same size, magnified, reduced, or blurred. Contemporary optics research is distant from common experience, seeking clues far more subtle than the shape of a piece of glass, with techniques more esoteric than abrasive polishing of a glass lens. The traditional dominance of glass in optics is now challenged by a host of synthetic materials exhibiting unusual optical behavior.
