| Abstract: | The letter presents numerical data and gives an explanation for the spontaneous creation of spatial patterns in narrow-ridge waveguide laser diodes by including the effect of diffraction and non-linear coupling between transverse modes and the active material. In addition, experimental measurements from several laser diodes are made and directly compared to the simulation. Excellent agreement between numerical and experimental data is found. |
