Single mode and stable polarization InGaAs/GaAs surface emitting laser grown on GaAs [311]B substrate

We demonstrate a completely single-mode and single-polarization operations of a InGaAs/GaAs vertical-cavity surface emitting laser (VCSEL) grown on a GaAs [311]B substrate. The device operates in a single transverse and longitudinal mode, with stable polarization state in the entire tested current range.
