Light-matter interactions in multilayer organic nanostructures give rise to an abundance of interesting phenomena, and provide a functional platform for useful optical devices with sophisticated designs via fine control of the optical properties of the constituent materials and the thicknesses of each layers. This thesis focuses on the theoretical and experimental study of linear and nonlinear optical (NLO) properties of multilayer organic nanostructures in order to characterize the interaction between light and matter within the multilayer structure from a fundamental point of view, and to improve the linear and NLO efficiency of layered devices for practical applications.Metallic Fabry-Perot cavities filled with organic materials, as a typical multilayer structure, demonstrate strong and ultrastrong light-matter interaction, where hybrid quantum states known as cavity polaritons are formed. Moreover, compared to strongly coupled exciton-photon cavities, double organic cavities exhibit interesting optical properties in the ultrastrong coupling regime, yielding a broken degeneracy of vacuum Rabi splittings due to breaking of the rotating wave approximation (RWA). For the NLO properties, resonant third-harmonic generation (THG) can be enhanced by cavity polariton states, and THG intensity is seen to be larger when the polariton state is more exciton-like.Two-dimensional (2D) perovskite-based planar photovoltaic cells, as another typical multilayer structure, exhibit greatly improved environmental stability and photostability under operating conditions comparing with their 3D counterparts. We have investigated and designed devices using optical modeling. The absorption in the photoactive layer can be enhanced due to light-matter interaction in multilayer structures by carefully designing the layer thicknesses. In addition, using a modied drift-diffusion model, charge-carrier recombination is studied, which limits to the device performance of modest-mobility perovskite solar cells, while depending on the layer thickness. Therefore, the thickness optimization is investigated considering both aspects, which guides device fabrication with high power-conversion efficiencies.Coextruded multilayered polymer lms containing a NLO chromophore, a new alignment strategy for NLO chromophore, are studied by the second-harmonic generation (SHG) technique, which give rise to a second-order nonlinear optical response.

This volume presents a considerable number of interrelated contributions dealing with the new scientific ability to shape and control matter and electromagnetic fields on a sub-wavelength scale. The topics range from the fundamental ones, such as photonic metamateriials, plasmonics and sub-wavelength resolution to the more applicative, such as detection of single molecules, tomography on a micro-chip, fluorescence spectroscopy of biological systems, coherent control of biomolecules, biosensing of single proteins, terahertz spectroscopy of nanoparticles, rare earth ion-doped nanoparticles, random lasing, and nanocoax array architecture. The various subjects bridge over the disciplines of physics, biology and chemistry, making this volume of interest to people working in these fields. The emphasis is on the principles behind each technique and on examining the full potential of each technique. The contributions that appear in this volume were presented at a NATO Advanced Study Institute that was held in Erice, Italy, 3-18 July, 2011. The pedagogical aspect of the Institute is reflected in the topics presented in this volume.

In recent years the field of semiconductor optics has been pushed to several extremes. The size of semiconductor structures has shrunk to dimensions of a few nanometers, the semiconductor-light interaction is studied on timescales as fast as a few femtoseconds, and transport properties on a length scale far below the wavelength of light have been revealed. These advances were driven by rapid improvements in both semiconductor and optical technologies and were further facilitated by progress in the theoretical description of optical excitations in semiconductors. This book, written by leading experts in the field, provides an up-to-date introduction to the optics of semiconductors and their nanostructures so as to help the reader understand these exciting new developments. It also discusses recently established applications, such as blue-light emitters, as well as the quest for future applications in areas such as spintronics, quantum information processing, and third-generation solar cells.

This book presents the recent progress in the field of nanophotonics. It contains review-like chapters focusing on various but mutually related topics in nanophotonics written by the world’s leading scientists. Following the elaboration of the idea of nanophotonics, much theoretical and experimental work has been carried out, and several novel photonic devices, high-resolution fabrication, highly efficient energy conversion, and novel information processing have been developed in these years. Novel theoretical models describing the nanometric light-matter interaction, nonequilibrium statistical mechanical models for photon breeding processes and near-field‐assisted chemical reactions as well as light‐matter interaction are also explained in this book. It describes dressed photon technology and its applications, including implementation of nanophotonic devices and systems, fabrication methods and performance characteristics of ultrathin, ultraflexible organic light‐emitting diodes, organic solar cells and organic transistors.

The investigation of light-matter interactions in materials, especially those on the nanoscale, represents perhaps the most promising avenue for scientific progress in the fields of photonics and plasmonics. This book examines a variety of topics, starting from fundamental principles, leading to the current state of the art research. For example, this volume includes a chapter on the sensing of biological molecules with optical resonators (microspheres) combined with plasmonic systems, where the response this system are described in a fundamental and elegant manner using coupled mode theory. Symmetry plays a major role in the book. One chapter on time reversal symmetry in electromagnetic theory describes how to control the properties of light (e.g. scattering and directionality of the flow of light) in materials with certain topological invariants. Another chapter where symmetry is prominent reformulates, using a gentle and pedagogical approach, Maxwell’s Equations into a new set of fields that reveal a “handedness” symmetry in electromagnetic theory, which can be applied to photonic systems in, for example, the sensing of chiral molecules and understanding the conditions for zero reflection. Also, for students and researchers starting in the field of nanoplasmonics, the book includes a tutorial on the finite element time domain simulation of nanoplasmonic systems. Other topics include photonic systems for quantum computing, nanoplasmonics, and optical properties of nano and bulk materials. The authors take a pedagogical approach to their topic, making the book an excellent reference for graduate students and scientists starting in the fields of photonics or plasmonics.

Two-dimensional (2D) materials have attracted tremendous interest since the study of graphene in the early 21st century. With their thickness in the angstrom-to-nanometer range, 2D materials, including graphene, transition metal dichalcogenides, phosphorene, silicene, and other inorganic and organic materials, can be an ideal platform to study fundamental many-body interactions because of reduced screening and can also be further engineered for nanophotonic applications. This book compiles research outcomes of leading groups in the field of 2D materials for nanophotonic physics and devices. It describes research advances of 2D materials for various nanophotonic applications, including ultrafast lasers, atomically thin optical lenses, and gratings to inelastically manipulate light propagation, their integrations with photonic nanostructures, and light–matter interactions. The book focuses on actual applications, while digging into the physics underneath. It targets advanced undergraduate- and graduate-level students of nanotechnology and researchers in nanotechnology, physics, and chemistry, especially those with an interest in 2D materials.
