Modeling and characterization of elastic wave propagation in micro-scale photonic crystals
… Filtering, guiding and mirroring of elastic waves are a few applications in which phononic crystals can be used. In this manuscript, the physical origins of phononic bandgaps were successfully determined using a one-dimensional model to isolate resonances contributing to the creation of …

Algorithms and technologies for photonic crystal modelling
… crystals was carried out using numerical methods. Photonic crystals are expensive and difficult to fabricate so there is a requirement for computer simulations that can quickly and accurately model how the crystal structure will affect the behaviour of light. A finite difference method was …

Terahertz oscillation and stimulated emission from planar microcavities
… with structural sizes in the range of the light wavelength, where the photonic modes are con- fined and the number of states is limited. In the smallest microcavities, i.e. micrometer sized optical resonators, the propagation of only one mode is permitted that is simultaneously amplified …

Predictive simulation and design of III-V heterostructures for light emission and detection
… on density functional theory (DFT) and the k·p method – calculations to analyse and optimise III-V semiconductor heterostructures for light emission and detection. III-V superlattices (SLs) have attracted significant interest for emission and detection at mid-infrared (mid-IR) wavelengths, for …

Theory and simulation of quantum nanostructures for integrated photonics
… employ the semi-empirical continuum-based k · p method to analyse the electronic and optical properties of QWs and QDs to enhance the capabilities of these devices. First, we present the QUDOS code: a free, open-source software package to underpin predictive analysis and design of QD …
