Along with pure circularly polarized light (CPL) emission, arbitrary-helicity controllability on spin polarized light emitting diodes (Spin-LEDs) is another strong point among any other CPL source, which was demonstrated at 10 K on the basis of the fact that the helicity of CPL depends on the spin direction of injected electrons. Reported in this paper is arbitrary-helicity control of CPL emitted at room temperature (RT) from the cleaved side facet of a lateral-type spin-LED with two ferromagnetic electrodes in an antiparallel magnetization configuration.
