We report lateral-type, GaAs/AlGaAs double hetero-structure (DH) spin-LEDs with stripe Fe spin injectors that exhibit
nearly pure circular polarization (CP) electroluminescence (EL) with current densities of J 10 A/cm2 or less. Experiments
with such spin-LEDs have made it possible to obtain experimental data that were not accessible in the first report [1,2]:
namely, clear experimental proof for the presence of a threshold J value at which the annihilation of minority-helicity CPEL component takes place.
