The monolithic integration of a spin valve, an amplifier, and a light emitting diode to form a magneto-optoelectronic integrated circuit on GaAs is demonstrated. The circuit converts the spin polarization information in the channel of the spin valve to an amplified change in light intensity with a gain of 20. The monolithic circuit therefore operates as a magnetoelectronic switch which modulates the light intensity of the light emitting diode.
