We report measurements of the lasing polarization from GaAs quantum wires grown on v-grooved (100) oriented substrates. Comparison is made with the polarization of emission from other quantum well structures formed on similar nonplanar substrates. The quantum wells lase in classic TE modes. The quantum wire emission is linearly polarized at an angle to the growth plane, but not aligned with any obvious device feature. © 2000 American Institute of Physics.

    Dichroism in the transmission of light (the dependence of the transmittance on the direction of polarization of light) is revealed in corrugated GaAs/AlAs superlattices grown on a nanofaceted A(311) surface. It is assumed that the observed effect is associated with the structural anisotropy,...

    Polarization of vertical-cavity surface-emitting lasers (VCSELs) grown on (001) GaAs substrate has been controlled by electro-optic birefringence. Birefringence was induced at the top distributed Bragg reflector by applying an electric field along the [001] direction. The cavity resonance of the...
