These are optical thin film designs incorporating metallic films. This project is focused on designing and fabricating innovative film structures for achieving unique properties, such as high optical transparency combined with high transverse conductivity. Metals such as silver, copper, and gold are particularly suitable because they have low loss-tangent values. It is the loss tangent (and not the imaginary part of the refractive index) that dictates the absorption losses in a metal.

Additionally, we have also been able to design and build antireflection coatings on highly reflective surfaces, such as aluminum and silver.
