Received February 7, 2011; revised April 16, 2011; accepted April 19, 2011; posted April 19, 2011 (Doc. ID 142374); published May 19, 2011 We report analytical solutions for spatial solitons supported by layers of a quadratically nonlinear (χð2Þ) material embedded into a linear planar waveguide. A full set of symmetric, asymmetric, and antisymmetric modes pinned to a symmetric pair of the nonli...

Abstract Threshold properties and pulsed output of AlGaInP visible-emitting lasers with an asymmetric waveguide structure a bulk active layer are analysed. The effects the current leakage, increased by heating laser due to proximity electrical pulse source Joule in around this When optimising design, waveguiding shown be important, leading threshold currents decreasing, injection efficiency inc...

in order to implement an integrated optical quantum circuit, designing waveguides based on the quantum box is of prime importance. to do this we have investigated optical waveguide both with and without optical pumping. the rate of absorption and emission using an array of algaas/gaas quantum box core/shell structure in the optical waveguide with various pumping intensities has computed. by con...

In this work we investigate the nonperturbative decay dynamics of a quantum emitter coupled to composite right/left handed transmission line (CRLH-TL). Our theory captures contributions from different spectral features waveguide, providing an accurate prediction beyond weak coupling regime, and illustrating multiple possibilities offered by nontrivial dispersion metamaterial waveguides. We show...

Waveguide slot arrays are a widely used solution to attain linearly polarized high-gain antennas. In this article, an all-metal T-shaped radiating element is conceived with the aim replace usual rectangular slots and circularly arrays, preserving their good properties. The polarization conversion made possible due inclusion of parasitic arm perpendicular main active slot. Due fact that second n...
