FIG. 1.

(Color) Measured intensity at the output of the multimode waveguide as a function of the input tilt angle , for (a) the linear regime (low power) and (b) the nonlinear regime ( peak power). The intensity profiles measured by the camera are displayed on a color scale: The normalized peak intensity for every angle is represented by red, whereas no light is represented by blue. The white dashed lines indicate the position of the ridge waveguide edges (the ridge width is ).

(Color) Simulated intensity evolution along the waveguide when the input is a Gaussian beam with FWHM and tilt angle , for (a) the linear regime and (b) the nonlinear regime ( peak power). The normalized intensity varies between 1 (red) and 0 (blue). is the propagation direction and is the transverse direction. The white dashed lines show the position of the ridge waveguide edges.

FIG. 3.

Output intensity distribution profiles for input tilt angles and , for (a) measured and (b) BPM (calculated). The solid lines refer to the linear regime and dashed lines to the nonlinear regime, peak input power . The thin vertical lines indicate the position of the ridge waveguide edges.
