Abstract

Optical switches, bistable optical devices, and spatial modulators (SLMs) are important key elements in optical computers and in optical data processing systems. In recent years this field has advanced tremendously; however, the lack of appropriate materials to implement theoretical design of optical hardware is often considered as a bottleneck in realizing the potential of this field. Organic materials may provide the ideal medium needed for this optical hardware. It is already known, for example, that such materials exhibit the extremely high nonlinear optical susceptibilities that are necessary for optical data processing. An all-optical device based on appropriate organic materials will operate on the intensity induced changes in the complex index of refraction, i.e., the absorptive and dispersive properties of the medium due to intensity induced population changes. Theory predicts that optical bistability can be observed in such materials. In this paper we examine the possibility of producing nonlinear optical devices based on organic nonlinearly absorbing materials.
