Abstract

� 2015 AIP Publishing LLC. We report a room temperature optically pumped Quantum Dot-based Spin-Vertical-External-Cavity Surface-Emitting laser (QD Spin-VECSEL) operating at the telecom wavelength of 1.3μm. The active medium was composed of 5 � 3 QD layers; each threefold group was positioned at an antinode of the standing wave of the optical field. Circularly polarized lasing in the QD-VECSEL under Continuous-Wave optical pumping has been realized with a threshold pump power of 11mW. We further demonstrate at room temperature control of the QD-VECSEL output polarization ellipticity via the pump polarization.
