Abstract: | The properties of controllable soliton switching in Kerr-type optical lattices with different modulation are investigated theoretically and simulated numerically. The results show that the optical lattices can be available for all-optical soliton switching through utilization for length-scale competition effects. And through longitudinal exponential-asymptotic modulation for the linear refractive index, the properties of soliton switching in the optical lattices can be improved. The
number of output channels of soliton switching can be controlled by the
parameters such as incident angle, asymptotic rate of longitudinal
modulation, guiding parameter and form factor. |
