Solitons are nonlinear waves that remain invariant as they propagate. Precise control of dispersion and nonlinear effects govern soliton propagation. In recent years Photonic crystals (PhCs) have attracted a great deal of attention due to the facility to engineer and enhance both their nonlinear and dispersive effects. In this article we show soliton pulse analysis in GaInP Photonic Crystal Waveguides using AUTO bifurcation analysis tool. We have demonstrated pulse compression at moderately slow velocities in GaInP Photonic Crystal Waveguides. This is enabled by the enhanced self phase modulation and strong negative group velocity dispersion in the Photonic Crystal Waveguides.
