2% on GaAs (311) B substrate for a polarization controlled vertical-cavity surface-emitting
laser (VCSEL). By increasing the In composition in GaInAs, the optical anisotropy in
photoluminescence (PL) intensity was increased. The anisotropy of 50% was obtained at
1.15/spl mu/m emission wavelength. We have demonstrated edge-emitting lasers and
VCSELs emitting at over 1.1/spl mu/m on GaAs (311) B substrate for the first time. The 1.15 …
