Observation of Two-Dimensional Surface Solitons in Asymmetric Waveguide Arrays
Observation of Two-Dimensional Surface Solitons in Asymmetric Waveguide Arrays
We report on the experimental observation of two-dimensional surface waves localized at the edge or in the corner of femtosecond laser-written waveguide arrays in fused silica. Increasing the power of the input beam allows one to observe a clear transition from a linear diffraction pattern to localized nonlinear surface states, …
