| Abstract |
Recently, highly absorbing dielectric films as optical coatings have been studied. By combining metals with highly absorbing dielectrics, strong optical interference can be obtained with a non-trivial phase change of the reflected waves. This effect allows the thickness of the coating layer to be remarkably reduced as compared to that of the conventional coating layer. With these properties, resonance behavior with structural color is observed in the structure composed of an ultra-thin absorbing medium on a metal substrate. In this presentation, we present theoretical modeling and experimental results on the ultra-thin film colorations and the possibilities for sensing applications. |
