Low switching threshold using nonlinearities in stopband-tapered waveguide Bragg gratings

We numerically study the nonlinear switching characteristics in a waveguide grating with a linearly tapered stopband. This type of design shows promising results in decreasing the threshold switching power, while simultaneously preserving a significant extinction ratio. We find that the switching th...
