(Color online) (a) Polarization-resolved EL spectra of the quantum-well spin-LED for zero magnetic field and . (b) Polarization degree vs magnetic field for a sample with a 750-nm-thick spin aligner, for a sample with a thin (50 nm) spin aligner and for direct optical unpolarized quantum-well excitation.
