Metal insulator multi-layer surface plasmon devices
Abstract/Contents
- Abstract
- Surface plasmon based devices have attracted significant of attention over the last decade with exciting applications like negative refraction, optical cloaking, perfect lenses, and meta-surfaces. They have also enabled highly efficient and compact electro-optical devices bridging the gap between optical (micron) and the electronics (nano) scale devices. At the heart of many of these devices and applications are multi-layer metal insulator structures, where the interaction of surface plasmons at various interfaces unlock these surprising properties. This thesis focuses on the scattering and transmission properties of plasmon modes in metal insulator multilayer structures. In the first part of the thesis, we will describe a theoretical model for standing wave resonances in Metal-Insulator-Metal surface plasmon cavities. These calculations, which are in excellent agreement with full field finite difference simulations, aid in furthering our understanding of plasmon phase pickup on reflection from the cavity terminations. This phase pickup is associated with the near-field energy storage at those terminations, and the imaginary part of the reflection coefficient is shown to be approximately proportional to the stored energy. We then focus on a different, yet related geometry for a surface plasmon antenna, a metal stripe wave guide above a metallic ground plane. Staggered confocal microscopy is used to study the scattering properties of the stripe antenna. CdSe/ZnS quantum dots are sandwiched between the stripe and ground plane. Dual purposing of the stripes as electrical lead and an optical element is illustrated through low temperature quantum confined stark effect measurements. Finite difference calculations of the surface plasmon transmission spectra through the truncated stripe waveguide cavity is shown to be well modeled by a two-path-two-mode coupled cavity model.
