Abstract

Binary information encoded within the spin of carriers can be transferred into corresponding right or left-handed circularly polarized photons emitted from an active semiconductor medium via carrier-photon angular momentum conversion. In order to attain maximized spin-injection at out-of-plane magnetic remanence, a number of material systems have been explored as possible solid-state spin injectors. However the electroluminescence circular polarization (PC) of emitted light was still limited at 3-4% at remanence.
