The NaPANIL project aims to develop processes, materials and tools, both for manufacturing and for control, for truly 3-dimensional nanosurfaces with feature dimensions ranging from 50 nm to several m. The nanosurfaces will be realised using various variants of nanoimprinting lithography. The dedicated application is to control light at nanostructured surfaces and a few potential high impact prod ...

Compared to conventional light sources, the light producing capacity of a light emitting diode (LED) is virtually unlimited at about a 1/10 of the energy consumption rate and a fraction of the production cost. Due to its point source characteristics an LED requires a means to collimate and shed the emitted light onto larger areas. Diffractive optics (DO) elements consisting of highly complex micro ...
