The structures of optical spectra of a semiconducting sphere are studied over a wide range of radius. The calculation is based on a ``microscopic nonlocal theory'' and we reformulate the theory to simplify the procedure. The nonlocal theory enables us to analyze correspondences between spectral peaks and exciton states directly, decompose a scattered field into an exciton contribution and the Mie scattering, and provide complex eigenenergies of the exciton-light coupled modes. The imaginary…

Exciton states and optical properties of carbon nanotubes

A self-consistent method is introduced for calculating the scattering light and induced current density due to excitons and the close relationship between a long-range electron-hole exchange interaction and a depolarization effect is clarified.

Crossover of exciton-photon coupled modes in a finite system

An exciton and a photon behave as a polariton in macroscopic materials while they can be treated almost independently in nanostructured ones. We have theoretically investigated the crossover of

Polariton optics of semiconductor photonic dots: weak and strong coupling limits

We develop coherent optics of dipole-active, dispersionless excitons in spherical semiconductor photonic dots (PDs). In the absence of any incoherent scattering, both the strong and weak coupling

Polariton optics of spherical nanostructures.

This thesis describes the completely coherent polariton optics of a spherical semiconductor photonic dot (PD). Our theoretical model solves the eigen-modes of the system to produce the polariton

Resonant three-dimensional photonic crystals

The theory of the exciton-polariton band structure of a resonant three-dimensional photonic crystal is developed for an arbitrary dielectric contrast and an arbitrary effective mass of an exciton

Anomalous exciton–radiation coupling in the nano-to-bulk crossover regime

Anomalous exciton–radiation coupling in the sample-size regime beyond the long-wavelength approximation (LWA) is discussed. In high-quality samples fabricated using the latest technologies, the

Semiconductor quantum dots reveal dipolar coupling from exciton to ligand vibration

Within semiconductor quantum dots (QDs), exciton recombination processes are noteworthy for depending on the nature of surface coordination and nanocrystal/ligand bonding. The influence of the

Photon-statistics dispersion in excitonic composites

Linear media are predicted to exist whose relative permeability is an operator in the space of quantum states of light. Such media are characterized by a photon statistics-dependent refractive index.

Theory of resonant radiation force exerted on nanostructures by optical excitation of their quantum states: From microscopic to macroscopic descriptions

We establish a theoretical framework that provides a bridge between the microscopic to macroscopic descriptions of the radiation force (RF) under a quantum resonance condition. By using this
