Abstract
We numerically investigate nonlinear propagation of ultrashort pulses in a one-dimensional photonic band gap structure. We find that, near t he band edge, nonlinear effects cause a dynamical shift in the locatio n of the band gap. We demonstrate that this nonlinear mechanism can in duce intensity-dependent pulse transmission and reflections. In additi on, pulse reshaping and pulse generation is observed. This phenomenon has important new applications in both optical limiting and optical sw itching.
