Abstract


Metamaterials in optical frequencies have a tremendous range of application, many of which require large area materials with fine features. Self assembly can provide an efficient route to fabricating structured optical metamaterials. From enabling fundamentally new effects, such as optical magnetism, to creating tailored absorption and transmission spectra, designing optical properties through structure offers a new mechanism for manipulating light. These systems require nanometric features on structures frequently below 100nm in size in order to gain the desired properties set. To date, demonstrations have relied on electron beam lithography, focused ion beam milling and other high resolution techniques with limited ability to cover larger areas. This has limited experimental exploration of large area application of metamaterials. Self assembled systems can be used either directly as metamateials or as templating structures to create ordered arrays of meta-atoms. In addition, these techniques can be applied at the unit cell level to create complex, structured and active metamaterials. In this presentation, I will describe efforts to utilize self assembly techniques to create optical metamaterials. Systems designed to control fluorescence, nonlinear properties and optical absorption will be discussed.
