Manipulating Optical Properties by Local-Field Effects and Nanostructuring



Local electric field, driving the atomic transition in an optical
material is, in general, different from the macroscopic field in the
medium. It contains the contributions from the fields of the surrounding
atoms or molecules. An even more interesting situation arises in case
of nanocomposite optical materials, which are nanoscale mixtures of two
or more homogeneous constituents, where the morphology can significantly
modify the local field. In this talk, I will discuss how local-field
effects and nanostructuring can be utilized for manipulating the optical
properties of nanocomposite materials. I will also talk about some
opportunities that local-field effects offer in the nonlinear optical
regime. Among those is, for example, the microscopic cascaded
contribution of the lower-order nonlinearities to the higher-order
nonlinear response. There can exists new phenomena that local-field
effects are yet to offer, and research in this field can bring up many
practical applications.
