- Countering spatial soliton breakdown in nematic liquid crystalsJeroen Beeckman
Department of Electronics and Information Systems ELIS, Liquid Crystals and Photonics Group, Ghent University, Sint Pietersnieuwstraat 41, 9000 Gent, Belgium
Opt Lett 34:1900-2. 2009..The use of this technique offers a major advantage for optical interconnects because the beam broadening can be reduced over much longer propagation distances...
- Finding exact spatial soliton profiles in nematic liquid crystalsJ Beeckman
Liquid Crystals and Photonics Group, Department of Electronics and Information Systems, Ghent University, Sint Pietersnieuwstraat 41, 9000 Gent, Belgium
Opt Express 18:3311-21. 2010..In this way it is also possible to find higher order solitons. The results in this work can be used to accurately design all-optical interconnections with soliton beams...
- Tuning of silicon-on-insulator ring resonators with liquid crystal cladding using the longitudinal field componentWout De Cort
Department of Information Technology, Photonics Research Group, Ghent University, Gent, Belgium
Opt Lett 34:2054-6. 2009..Tuning of the liquid crystal birefringence affects primarily the longitudinal component of the electric field. We achieve a tuning range of 0.6 nm. Through simulation and experiment we perform a thorough study of this phenomenon...
- A finite element beam propagation method for simulation of liquid crystal devicesPieter J M Vanbrabant
Department of Electronics and Information Systems, Ghent University, Gent, Belgium
Opt Express 17:10895-909. 2009....
- Preferentially oriented BaTiO3 thin films deposited on silicon with thin intermediate buffer layersJohn P George
Department of Electronics and Information Systems, Ghent University, Sint Pietersnieuwstraat 41, Gent, 9000, Belgium
Nanoscale Res Lett 8:62. 2013..A BaTiO3 film of 150-nm thickness, deposited on a buffer layer of 7.2 nm, shows a dielectric constant of 270, remnant polarization (2Pr) of 5 μC/cm2, and coercive field (Ec) of 60 kV/cm...
- Dipole radiation within one-dimensional anisotropic microcavities: a simulation methodLieven Penninck
Electronics and Information Systems Department, Ghent University, Ghent, Belgium
Opt Express 19:18558-76. 2011..The dependency of the intensity and the polarization on the direction of emission is illustrated for a number of anisotropic microcavities...
