Energy of the upper photonic band edge of photonic crystals A, B and C as the intensity of the pump field is varied. Since crystals A and B are essentially linear for this range of pump field intensity, their upper band edges are unaffected by the pump field. We see here that by applying a pump field with intensity around 8 × 1010W/cm2, the upper band edge of crystal C can be shifted to just slightly below that of crystal A, effectively removing the photonic barrier separating the two waveguides in the heterostructure
