Controlling light transmission with nanostructured metallic surfaces : applications in polarimetry, transparent electrodes, and anti-reflective coatings
Abstract/Contents
- Abstract
- Metallic structures such as antennas and waveguides are widely used to concentrate and guide electromagnetic radiation into electronic circuits at radio and microwave frequencies. Because of their high conductivity, metals are also used for the wiring in electronic circuitry. At near infrared and visible frequencies, however, metals have been underutilized. In this spectral range, dielectric elements such as lenses and waveguides are used to manipulate electromagnetic radiation. Recent progress in nanotechnology has opened up opportunities to make and characterize metallic structures at the nano scale, which are requirements for use of metals in this spectral range. Miniaturized metallic devices could potentially replace some of their bulky dielectric counterparts at near IR and visible frequencies, while simultaneously performing an additional electronic function. This would enable new optical applications that are not possible with dielectrics alone. This dissertation presents our work on controlling light transmission with nanostructured metallic films for three applications, all of which are typically the domain of dielectrics: polarimeters, anti-reflective coatings, and transparent electrodes. In all three applications, the nanostructured metallic film simultaneously performs optical (light transmission) and electronic (charge extraction) functions. We perform full-field electromagnetic simulations to characterize and optimize these metallic nanostructures. We also experimentally show the applicability of these designs for real devices through integration with semiconductor photodetectors and performing photocurrent and reflection measurements. The demonstrated devices extend the reach of metal optics to a wide range of optoelectronic applications including displays, touch screens, solar cells, and polarimetric imagers and sensors.
