Description

Analysis and design of photonic integrated components and circuits, with emphasis on contemporary guided-wave nano-photonics. Expertise covers a range of advanced simulation techniques, both for linear and nonlinear propagation, with custom (home-developed) and commercial software tools. Particular areas of expertise include plasmonics, silicon photonics and other optoelectronic devices (both in terms of optical wave propagation in the context of Maxwell’s equations and carrier dynamics). Other expertise is on Liquid Crystal photonics (optical wave propagation and liquid crystal reorientation/switching) and specialty types of fibres (microstructured optical fibres, photonic crystal fibres). Finally, we do have some activity on switchable diffraction devices, such as Spatial Light Modulators or other addressable diffraction gratings.
