Abstract

We report on the experimental observation of dynamical collapses which address selectively the TM-mode of a laser subject to optical feedback with variably rotated polarization. Simultaneously, the TE-mode which remains the dominant lasing mode exhibits power bursts. We analyze the relative phase shift between the feedback fields into the TE- and TM-mode and find that the dynamical collapses, observed in a specific range of polarization rotation angles, can be attributed to large phase shift feedback conditions applied on the TM-mode.
