In conventional lasers, the optical cavity that confines the photons also determines essential characteristics of the lasing modes such as wavelength, emission pattern, ... In random lasers, which do not have mirrors or a well-defined cavity, light i

In this thesis, theories for the solution of diffraction problems involving both singly periodic and doubly periodic structures are presented. The studies have been motivated by two fields of application. The first of these is the use of singly perio

Comprehensive theoretical and numerical studies of the effects of dispersion and absorption on the Anderson localization of classical waves in weakly disordered, one-dimensional stacks composed of dispersive metamaterials and normal materials are pre

We study ID stacks comprising alternating layers of normal and metamaterials, with disorder in both refractive index and layer thickness, and show strong suppression of localisation with only index disorder. © 2008 Optical Society of America.

We study wave propagation in mixed, 1D disordered stacks of alternating right- and left-handed layers and reveal that the introduction of metamaterials substantially suppresses Anderson localization. At long wavelengths, the localization length in mi

The frequency shift of sources embedded in a two-dimensional photonic cluster composed of circular cylinders is considered and the effects of cluster shape and orientation are investigated. It is found that by carefully tailoring the shape of the clu

The usual technique for calculating the mesoscopic conductance of materials is based on Pichard's transfer matrix method [J.L. Pichard, Thesis, University of Paris, Orsay, 1984]. The essential ideas of the theory of conductance for electronic systems

We consider defect modes created in complete gaps of 2D photonic crystals by perturbing the dielectric constant in some region. We study their evolution from a band edge with increasing perturbation using an asymptotic method that approximates the Gr

We consider the Hurwitz zeta function ζ(s,a), and form two parts ζ+ and ζ- by symmetric and antisymmetric combinations of ζ(s,a) and ζ(s,1-a). We consider the properties of ζ+ and ζ-, and then show that each may be decomposed into parts denote
