  A three-dimensional ordered and self-organized semiconductor system emitting
highly-polarized light in the yellow-orange visible range (580-650 nm) is
presented, comprising self-assembled in-plane AlInP wires vertically stacked in
regularly-spaced columns. More than 200 wires per column without detectable
defect formation could be stacked. Theoretical simulations and
temperature-dependent photoluminescence provided a benchmark to engineer
multilayered structures showing internal quantum efficiency at room temperature
larger than comparable quantum wells emitting at similar wavelengths. Finally,
proof-of-concept light emitting diodes (LED) showed a high degree of light
polarization and lower surface parasitic currents than comparable quantum well
LEDs, providing an interesting perspective for high-efficiency polarized
yellow-orange light emitting devices.
