Abstract
There is disclosed and claim a multi-layer polymeric optical element including at least two poled film members exhibiting nonlinear optical susceptibility. The films may be poled in an ordinary atmosphere under relatively mild conditions, or corona poled at high voltage. The elements are particularly useful for periodic or quasi-random optical applications such as parametric amplification of light or frequency doubling.
Claims20
A method of preparing a multilayer polymeric nonlinear optical element comprising providing a plurality of poled polymeric film members followed by securing said poled polymeric film members in facing relationship wherein said plurality of poled polymeric film members are capable of optical communication between layers so defined.
A multilayer optical element comprising in combination a plurality of nonlinear polymer optical film layers secured in facing relationship each poled in an electric field prior to being secured in facing relationship and wherein said plurality of layers defines a periodic nonlinear optical medium.
