Journal ArticleDOI
Measurement of the self-induced waveguide of a solitonlike optical beam in a nematic liquid crystal
TL;DR: In this paper, the non-locality of the optical response of a nematic liquid crystal in planar configuration is characterized using phase-measurement interferometry, and a good agreement is obtained between the experiment and a full (2+1)-dimensional numerical simulation of the nonlinear optical beam propagation in the cell.
Journal ArticleDOI
Nanophotonic Polarization Diversity Demultiplexer Chip
F. Van Laere,Tiziana Stomeo,Cyril Cambournac,M. Ayre,Romain Brenot,Henri Benisty,Gunther Roelkens,Thomas F. Krauss,D. Van Thourhout,Roel Baets +9 more
TL;DR: In this paper, a photonic-crystal demultiplexer with 2D-grating couplers was proposed for coarse WDM applications, and the performance of the device was evaluated using integrated p-i-n photodetectors.
Journal ArticleDOI
Slow-light regime and critical coupling in highly multimode corrugated waveguides
TL;DR: In this article, large and periodically corrugated optical waveguide structures are shown to possess specific modal regimes of slow-light propagation that are easily attainable by employing coupled-mode theory and the plane-wave expansion method.
Journal ArticleDOI
Simulation of 2-D lateral light propagation in nematic-liquid-crystal cells with tilted molecules and nonlinear reorientational effect
TL;DR: In this paper, the authors used a two-dimensional (2D) problem with TM polarization and a parallel liquid-crystal orientation where the molecules are only tilted and not twisted, thus reducing the problem to a scalar one.
Journal ArticleDOI
Photonic-Crystal Demultiplexer With Improved Crosstalk by Second-Order Cavity Filtering
TL;DR: In this article, a photonic-crystal demultiplexer is implemented on a silicon-on-insulator (SoI) platform, which operates on the principle of mini-stopbands of broader waveguides.
