Abstract

The 780-nm quantum well vertical cavity surface emitting lasers (VCSEL) grown on a second-degree-off misoriented (0 0 1) substrate toward (1 1 1)A exhibit high polarization suppression ratio. The main polarization is always along [-1 1 0] direction for all the lasers over the entire operating currents. The gain/loss difference between two competing polarization modes in VCSEL is investigated by measuring the subthreshold spectral linewidth to understand the physical origin of this polarization selectivity. The obtained modal gain/loss difference is about 3.0 cm^-1 which is sufficiently large for the polarization stabilization and amounts to 4% of threshold modal gain.
