Download or read book The Nanoscale Optical Properties of Complex Nanostructures written by Jordan A. Hachtel and published by Springer. This book was released on 2017-12-09 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents studies of complex nanostructures with unique optical responses from both theoretical and experimental perspectives. The theory approaches the optical response of a complex structure from both quantum-mechanical and semiclassical frameworks, and is used to understand experimental results at a fundamental level as well as to form a quantitative model to allow the design of custom nanostructures. The experiments utilize scanning transmission electron microscopy and its associated analytical spectroscopies to observe nanoscale optical effects, such as surface plasmon resonances, with nanometer-scale spatial resolution. Furthermore, there is a focus in the dissertation on the combination of distinct techniques to study the difficult-to-access aspects of the nanoscale response of complex nanostructures: the combination of complementary spectroscopies, the combination of electron microscopy and photonics, and the combination of experiment and theory. Overall, the work demonstrates the importance of observing nanoscale optical phenomena in complex structures, and observing them directly at the nanoscale.
Download or read book Optical Properties of Metallic Nanoparticles written by Andreas Trügler and published by Springer. This book was released on 2016-03-29 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the fascinating world of plasmonics and physics at the nanoscale, with a focus on simulations and the theoretical aspects of optics and nanotechnology. A research field with numerous applications, plasmonics bridges the gap between the micrometer length scale of light and the secrets of the nanoworld. This is achieved by binding light to charge density oscillations of metallic nanostructures, so-called surface plasmons, which allow electromagnetic radiation to be focussed down to spots as small as a few nanometers. The book is a snapshot of recent and ongoing research and at the same time outlines our present understanding of the optical properties of metallic nanoparticles, ranging from the tunability of plasmonic resonances to the ultrafast dynamics of light-matter interaction. Beginning with a gentle introduction that highlights the basics of plasmonic interactions and plasmon imaging, the author then presents a suitable theoretical framework for the description of metallic nanostructures. This model based on this framework is first solved analytically for simple systems, and subsequently through numerical simulations for more general cases where, for example, surface roughness, nonlinear and nonlocal effects or metamaterials are investigated.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Plasmonic nanostructures are of great interest due to the broad range of applications from biodetection to metamaterial. The desired optical functionality of these nanostructures can only be realized if the designed geometries and constituent material quality are accurately reproduced experimentally. This dissertation research developed new fabrication methods to create planar and freestanding plasmonic nanostructures, including two-dimensional (2D) planar gold (Au) nanoparticle quasicrystals, one-dimensional (1D) Au nanoparticle arrays, and ring-loaded Au nanoparticle dimer nanoantennas. The measured and modeled optical properties of each type of structure were found to be in strong agreement with one another, thereby confirming the effectiveness of the fabrication approaches in reproducing the designed structure. In Chapter 2, planar 2D plasmonic quasicrystal arrays composed of spherical Au nanoparticles were created by Au-enhanced oxidation of lithographically patterned stacks of evaporated amorphous silicon (a-Si) and Au thin films. In contrast to 2D periodic plasmonic structures, which can be accurately simulated for arbitrarily shaped nanoparticles, computationally efficient models for quasicrystals require spherical particle geometries. Using the process developed in this research, broadband Ammann-Beenker and multiband Penrose plasmonic quasicrystals were fabricated and optically characterized. The measured transmission spectra of the fabricated structures agreed well with simulation, thereby enabling an experimental validation of the modeled interaction between the plasmonic and photonic modes of the two structures. In Chapter 3, freestanding 1D Au nanoparticle arrays encapsulated within a silicon dioxide (SiO2) shell were produced by Au-enhanced oxidation of Au-coated, surface modulated Si nanowires. This lithography-free process overcomes the linear relationship between nanoparticle diameter and interparticle spacing imposed by the Rayleigh instability, and provides accurate and reproducible control of both of these parameters over a wide range of particle diameters and spacings. The modeled optical properties of fabricated 1D arrays were confirmed experimentally by extinction measurements of a randomly oriented ensemble of wires as well as by scanning transmission electron microscopy (STEM) electron energy loss spectra (EELS) and energy filtered transmission electron microscopy (EFTEM) analysis of individual wire arrays. In Chapter 4, a nanoring-loaded dimer nanoantenna was designed to give a multiband optical plasmonic response. The center wavelength and bandwidth of the two bands was varied by modifying the nanoring inner diameter. A top-down process was optimized to reproducibly fabricate the ring-loaded nanoantenna with sub-10 nm wide gaps between the three particles and an inner/outer nanoring diameter of 30nm and 55nm, respectively. Electromagnetic modeling showed that the multi-band response originated from differences in coupling between the nanoring and nanoparticle building blocks for the long- and short-wavelength resonances. The optical response was also understood by modeling the electric/magnetic field and charge distribution of the nanoantennas at the two resonant wavelengths.

Book excerpt: This book provides readers with a detailed overview of second- and third-order nonlinearities in various nanostructures, as well as their potential applications. Interest in the field of nonlinear optics has grown exponentially in recent years and, as a result, there is increasing research on novel nonlinear phenomena and the development of nonlinear photonic devices. Thus, such a book serves as a comprehensive guide for researchers in the field and those seeking to become familiar with it. This text focuses on the nonlinear properties of nanostructured systems that arise as a result of optical wave mixing. The authors present a review of nonlinear optical processes on the nanoscale and provide theoretical descriptions for second and third-order optical nonlinearities in nanostructures such as carbon allotropes, metallic nanostructures, semiconductors, nanocrystals, and complex geometries. Here, the characterization and potential applications of these nanomaterials are also discussed. The factors that determine the nonlinear susceptibility in these systems are identified as well as the influence of physical mechanisms emerging from resonance and off-resonance excitations. In addition, the authors detail the effects driven by important phenomena such as quantum confinement, localized surface plasmon resonance, Fano resonances, bound states, and the Purcell effect on specific nanostructured systems.

Download or read book Amorphous Nanophotonics written by Carsten Rockstuhl and published by Springer Science & Business Media. This book was released on 2013-02-15 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first comprehensive overview over amorphous nano-optical and nano-photonic systems. Nanophotonics is a burgeoning branch of optics that enables many applications by steering the mould of light on length scales smaller than the wavelength with devoted nanostructures. Amorphous nanophotonics exploits self-organization mechanisms based on bottom-up approaches to fabricate nanooptical systems. The resulting structures presented in the book are characterized by a deterministic unit cell with tailored geometries; but their spatial arrangement is not controlled. Instead of periodic, the structures appear either amorphous or random. The aim of this book is to discuss all aspects related to observable effects in amorphous nanophotonic material and aspects related to their design, fabrication, characterization and integration into applications. The book has an interdisciplinary nature with contributions from scientists in physics, chemistry and materials sciences and sheds light on the topic from many directions.
