A process, comprising: a) reacting a an alkoxysilane, an
(epoxy)alkoxysilane, and a fluorinated alkoxysilane to form a fluorinated
sol-gel polymer; and b) reacting a nonlinear optical chromophore
comprising a donor, a .pi.-bridge, an acceptor, and at least one
alkoxysilyl group with the fluorinated sol-gel polymer to form a
nonlinear optical fluorinated sol-gel polymer.
