Third-order nonlinear optical processes potential applications

In order to fully use the potential of various structures prepared by this technique, an important step is a careful characterization of L-B films. In our laboratory, a number of spectroscopic and surface-sensitive techniques are used. Both second and third-order nonlinear optical processes have been observed using L-B films. The organization of this paper is as follows. First, some of the techniques used for the characterization of L-B films are discussed. Then some interesting examples of control of order and conformation in the L-B films are presented. This is followed by a subsection, which presents results of the study of both second and third-order nonlinear optical processes in L-B films. Finally, possible applications of L-B films in nonlinear optical devices are discussed.
