Image of FIG. 1.
FIG. 1.

(a) Schematic diagrams of the spin-LEDs with a and Fe injector layer, indicating that injection of opposite spins into the quantum wells leads to the emission of circularly polarized light with opposite helicities and (b) the magnetic field dependencies of the EL polarization degrees for spin-LEDs with a and Fe injector layer, exhibiting opposite sign. The solid lines represent magnetization measurements displayed on an arbitrary scale.

Image of FIG. 2.
FIG. 2.

(a) Schematic diagram of the measurement configuration for photoexcited spin detection and (b) the magnetic field dependence of the resulting detection efficiency in a -covered spin-LED. The solid line represents the magnetization measurement displayed on an arbitrary scale.

Image of FIG. 3.
FIG. 3.

(a) Schematic diagram of the optical communication experiment and (b) the magnetic field dependence of the photocurrent (normalized to the zero-field value) in a -covered detector spin-LED upon irradiation by emitter spin-LEDs with a (top panel) and (bottom panel) Fe injector layer. The dashed lines indicate a parabolic background behavior; (c) a comparison of the data shown in (b) at low magnetic fields. The solid lines are guides to the eye.
