Abstract
One of the attractive features of solitons in general is their "robustness," which has been discussed for temporal solitons in optical fibers by C. R. Menyuk.1 That is, a true soliton should retain its solitonic properties when its amplitude or phase is perturbed during propagation. This concept has been demonstrated in fibers for perturbations such as loss, amplification, and frequency filtering.1-3 One would expect robustness for spatial solitons against similar perturbations. However, it is not known how a spatially anisotropic linear phase chirp across the soliton beam would affect its propagation. In this work we report an experimental study of the effect of such perturbations on soîilon propagation in an AlGaAs planar waveguide.
