Scattering in structured photonic media for classical and quantum light manipulation
Abstract/Contents
- Abstract
- Understanding and controlling the light scattering properties of nanophotonic structures is crucial for various applications. As a few examples, one can manipulate the color of nanoparticles, design invisibility cloaks, and create band gaps in periodic structures via suitable engineering of scattering properties. The light-scattering properties of an object depend on its own electromagnetic properties as well as on the dielectric properties of the environment it is placed in. In this thesis, we start with a detailed investigation of the scattering of classical or "coherent" light from a dielectric scatterer placed inside an otherwise uniform uniaxial hyperbolic medium. The dielectric object placed in a hyperbolic medium exhibits very different scattering properties as compared to its usual scattering behavior in an isotropic medium such as air. This points us to exciting opportunities for controlling scattering response by co-engineering both the scattering object and the environment it is placed in. Moving on, for the remainder of the thesis, we explore the scattering of single surface plasmon polariton (SPP) by atoms based on a proposed fully quantum mechanical model. SPPs are hybrid oscillations of electromagnetic fields and free electrons in metals and are known to significantly enhance light-matter interaction providing unique advantages. We first discuss the scattering of a single SPP by an atom and show a novel resonance arising from the strong interaction with small wavelength plasmons. Next, we present a proposal of electromagnetically induced transparency (EIT) like response realized using only two-level atoms. We also show the possibility of realizing mirrors and other optical devices using only hundreds of atoms. Finally, we discuss two-dimensional periodic atomic lattices interacting with a single SPP. Here, we propose various applications including slowing light to extremely small group velocities in atomic lattices, design of atomic lattice-based metamaterials, and design of a broad class of photonic Chern insulators.
