Abstract

Investigation into the role of polarization in optical feedback and its impact on lasers’ complex dynamics is an area of increasing interest [1]. We perform a comprehensive experimental research on high-power semiconductor lasers that possess a non-zero TM-mode power (typically few percent of the total power) and elliptical polarization in solitary configuration. When subject to a self-feedback with variably rotated polarization interesting effects are identified, such as dynamical collapses which address selectively the TM-mode of the laser and the appearance of a significant splitting in the optical spectrum (typically few nm).
