A new class of nanostructured polymer optical materials can mimic biological optical materials. Application to gradient refractive index (GRIN) lenses with an unprecedented variety of index gradients and a nonlinear 1-D photonic crystal are described.
Designing photonic devices using organic nonlinear dye/polymer composites requires an accurate determination of the index. A model of the wavelength and concentration dependence of the index that includes the density dependence is given.
