Abstract Spin-polarized light-emitting diodes (Spin-LED) consisting of ferromagnetic electrodes, an ultra-thin tunneling barrier layers and semiconductor LED structure can emit circularly polarized light (CPL) through radiative recombination of spin-polarized electrons and holes. A lateral-type spin-LED with crystalline AlOx tunnel barrier layers have been developed for practical applications and have achieved pure CPL emission, electrical helicity control and CPL detection at room temperature. This article reviews recent progress on spin-photonic devices such as spin-LEDs and spin-photodiodes and introduces the applications based on CPL.
