a b s t r a c t In this paper we review a recently developed finite-difference time-domain (FDTD) iterative technique for the analysis of periodic structures at oblique incidence. We show how it can be implemented in FDTD code and estimate required c

We present designs that enable a significant increase of solar absorption in ultra-thin (100–300 nm) layers of gallium arsenide. In the wavelength range from 400–860 nm, 90–99.5% solar absorption is demonstrated depending on the photonic crysta

We show that the optical modes of a periodic nanostruc- ture with frequency dependent dielectric constant (i.e., a dispersive optical nanostructure), in general can be written as an ordinary eigen- value problem of a \dielectric function operator", f

We introduce a finite difference discretization of semiconductor drift-diffusion equations using cylindrical partial waves. It can be applied to describe the photo-generated current in radial pn-junction nanowire solar cells. We demonstrate that the

A multiscale method is proposed for modeling elements of optical chemosensors based on photonic crystals. The method is based on the first-principles quantum-chemical and electrodynamic calculations. A technique is proposed that takes into account el

In this work we consider a special case of the Perfectly Matched Layer (PML) divergence which is observed by the simulation of the planar periodic structures such as photonic crystal slabs or antenna arrays. This divergence is caused by an excitation

We propose two complementary approaches for solution of the coupled Maxwell-Liouville equations within the finite-difference time domain (FDTD) framework. The two methods are specifically designed to eliminate self-interaction, which often appears sp

Optical properties of periodic structures can be calculated using the transfer-matrix approach, which establishes a relation between amplitudes of the wave incident on a structure with transmitted or reflected waves. The transfer matrix can be used t
