Optical properties of surface-patterned nanostructures

This concepts article describes our developments in nanopatterning related to photonics. We have a nanopatterning toolkit that can generate functional, nanostructured surfaces at nm-length scales and over cm²-areas in a single (or small number of) step(s). This paper will focus on three examples of surface-patterned nanostructures and their optical properties: (i) one-dimensional arrays of metallic nanoparticles; (ii) arrays of small-diameter ZnO nanowires; (iii) mesoscale structures of CdSe/ZnS nanocrystals. The potential for advances in nanopatterning to contribute to a broad range of light-based applications will be discussed.
