Nonlinear transmission and light localization in photonic-crystal waveguides

Nonlinear transmission and light localization in photonic-crystal waveguides

We study light transmission in two-dimensional photonic-crystal waveguides with embedded nonlinear defects. First, we derive effective discrete equations with long-range interaction for describing the waveguide modes and demonstrate that they provide a highly accurate generalization of the familiar tight-binding models that are employed, e.g., for the study of coupled-resonator optical waveguid...

Nonlinear light propagation in chalcogenide photonic crystal slow light waveguides.

Optical nonlinearity can be enhanced by the combination of highly nonlinear chalcogenide glass and photonic crystal waveguides (PCWs) providing strong optical confinement and slow-light effects. In a Ag-As(2)Se(3) chalcogenide PCW, the effective nonlinear parameter γeff reaches 6.3 × 10(4) W(-1)m(-1), which is 200 times larger than that in Si photonic wire waveguides. In this paper, we report t...

Nonlinear Gain Saturation in Active Slow Light Photonic Crystal Waveguides

Nonlinear GaInP Photonic Crystal Waveguides

We report highly nonlinear GaInP photonic crystal waveguides. An extremely large hybrid nonlinearity was demonstrated in a static experiment as well as in a wavelength conversion scheme at 10 Gbit/s. Highly efficient four wave mixing was also demonstrated for either CW or pulsed pump signals. Photonic crystyals; Nonlinear optics; Nonlinear wave mixing

Nonlinear Localized Modes In Photonic Crystal Waveguides

E xamples of the most significant recent research in optics and engineering are published each year in the December issue of OPN. This issue is comprised of short descriptions of the "hottest" topics in current optics research. Selection criteria applied to submissions are as follows: • the accomplishments described must have been published in a refereed journal in the year prior to publication...
