| A multimode optical fiber with a D-shaped cross-section has already been proved to constitute a privileged system to image wave functions of a chaotic system. Nevertheless, diffraction of light at the fiber input precludes the excitation of individual wave functions and particularly the scar modes we want to investigate. We show that a mechanism of scar modes selection can be induced by the introduction of a localized gain. |
