Applying the resonant-state expansion to realistic materials with frequency dispersion
Hame Sehmi, Wolfgang Langbein, Egor Muljarov
The dispersive resonant-state expansion, developed for an accurate calculation of the resonant states in open optical systems with frequency dispersion, is applied here to realisti…

Terahertz emitters based on microcavity dipolaritons
A. Seedhouse, J. Wilkes, V. D. Kulakovskii +1
We propose the use of dipolaritons -- quantum well excitons with large dipole moment, coupled to a planar microcavity -- for generating terahertz (THz) radiation. This is achieved…

Optimizing the Drude-Lorentz model for material permittivity: Examples for semiconductors
Hame S Sehmi, Wolfgang Langbein, Egor A Muljarov
Approximating the frequency dispersion of the permittivity of materials with simple analytical functions is of fundamental importance for understanding and modeling their optical p…
