Polarization of 8×8 vertical cavity surface emitting laser (VCSEL) arrays is completely controlled. These index-guided VCSELs have a 6×5 μm rectangular poststructure consisting of DBR mirrors. All 64 VCSELs emit fundamental single-mode and linearly polarized light with a polarization angle deviation of only 2.9°. Their light output characteristics are almost the same as those of conventional 6×6 μm polarization-uncontrolled VCSELs.
