Discrete Spatial Optical Solitons in Waveguide Arrays
We report the observation of discrete spatial optical solitons in an array of 41 waveguides. Lightwas coupled to the central waveguide. At low power, the propagating ﬁeld spreads as it couples tomore… Expand
The nonlinear optical properties of AlGaAs at the half band gap
We report experimental values for the nonlinear optical coefficients of AlGaAs, in the half-band-gap spectral region. The dispersion of the nonlinear refractive-index coefficient, n/sub 2/, is… Expand
Experimental Observation of Linear and Nonlinear Optical Bloch Oscillations
We experimentally demonstrate the occurrence of optical Bloch oscillations in a waveguide array with linearly growing effective index of the individual guides. We monitored the output profiles for… Expand
Compact and silicon-on-insulator-compatible hybrid plasmonic TE-pass polarizer.
Hybrid plasmonic waveguides consisting of a metal plane separated from a high-index medium by a low-index spacer have recently attracted much interest. Here we show that, by suitably choosing the… Expand
Coated nonmagnetic spheres with a negative index of refraction at infrared frequencies
Received 4 October 2005; revised manuscript received 28 November 2005; published 6 January 2006A three-dimensional lattice of micron-scale coated spheres is shown to have an isotropic negative index… Expand

We show that two regimes of diffraction exist in arrays of waveguides, depending upon the input conditions. At higher powers, normal diffraction leads to self-focusing and to the formation of bright… Expand
Compact highly-nonlinear AlGaAs waveguides for efficient wavelength conversion.
We report on the efficient nonlinear optical interactions in AlGaAs strip-loaded waveguides with a wafer composition specifically designed to increase the nonlinear coefficient. We demonstrate a… Expand
Voltage-Controlled Switching and Thermal Effects in VO2 Nano-Gap Junctions
Voltage-controlled switching in lateral VO2 nano-gap junctions with different gap lengths and thermal properties was investigated. The effect of Joule heating on the phase transition was found to be… Expand
Observation of spatial optical solitons in a nonlinear glass waveguide.
We report the observation of spatial optical solitons due to the Kerr nonlinearity in a planar glass waveguide and present measurements of the nonlinear response obtained by placing a pinhole at the… Expand
Propagation characteristics of hybrid modes supported by metal-low-high index waveguides and bends.
Hybrid-mode waveguides consisting of a metal surface separated from a high index medium by a low index spacer have attracted much interest recently. Power is concentrated in the low index spacer… Expand
