Abstract
A polymer thin film and method of making the thin film, the thin film having at least one polymeric structure for use as an organic optical component. The thin film includes a first layer of an optically transmissive first polymer having a first refractive index, and having a surface in which is defined at least one retaining feature, an optically transmissive UV curable second polymer retained within the retaining feature, the second polymer having a second refractive index which is greater than the first refractive index, and an overlay of the second polymer having a thickness in the range 0.001 &mgr;m to 1.5 &mgr;m over the surface of the first layer.
