Laser Action on 'Scar'-Modes and KAM-Transition to Chaos in Semiconductor Diode Lasers with Deformed Resonators

摘要

Measurements of the optical spectra of semiconductor injection lasers with deformed cylinder resonators show direct and unique signatures of laser action on scar-modes and of the Kolmogorov-Arnold-Moser (KAM) transition from integrability to chaos. The diode lasers studied in the present work operate with transverse electric (TE) polarization resulting in laser action on (partially) chaotic whispering gallery modes for all deformations. This observation is in contrast to the stable and quasi-stable, bouncing-ball type "bow-tie" modes of unipolar semiconductor lasers having the same resonator geometry but emitting with transverse magnetic (TM) polarization.
