We present an octave spanning supercontinuum (at the -35 dB level) ranging from 1100 nm to 2500 nm in InGaP photonic wire waveguides that are bonded to a silicon substrate and pumped by an ultrashort pulsed laser centered at 1550 nm. OCIS codes: (130.4310) Integrated optics, Nonlinear; (190.4400) Nonlinear optics, materials; (320.6629) Ultrafast optics, supercontinuum generation; (90.4390) Nonl...

PT-Symmetry is one of the interesting topics in quantum mechanics and optics. One of the demonstration of PT-Symmetric effects in optics is appeared in the nonlinear directional coupler (NLDC). In the paper we numerically investigate the stability of temporal bright solitons propagate in a PT-Symmetric NLDC by considering gain in bar and loss in cross. By using the analytical solutions of pertu...

This paper presents two-dimensional (2-D) finite difference time domain (FDTD) simulations of low-loss rightangle waveguide bends, T-junctions and crossings, based on high index-contrast waveguides. Such structures are essential for the dense integration of optical components. Excellent performance characteristics are obtained by designing the waveguide intersection regions as low-Q resonant ca...
