ABSTRACTNonlinear optical phenomena have been investigated over the last three
decades in many different materials and a great deal of progress has been
made in both the basic science and device applications.(1] Although interest
in nonlinear organic materials dates back to the early days of nonlinear
optics, it is only in the last five years that progress has been sustained
and rapid. The purpose of this paper is to examine progress in developing
new nonlinear organic materials and in their application to devices for
comparison with current state-of-the-art devices using other material
systems.
