FDTD modelling of chirped pulse propagation through a mini-stopband in a 2D photonic crystal waveguide

The FDTD method is used to study chirped pulse propagation in photonic crystal waveguides. In particular the carrier wavelength of the pulse is swept across the bandwidth of a mini-stopband feature and interesting, nonstandard pulse compression behaviour is observed. To further study this, increased frequency resolution across the MSB feature is used and the pulse width is varied.
