Abstract

We propose the scheme of a spin-optronic device, optical analog of Datta and Das spin transistor for the electrons. The role of the ferromagnetic-nonmagnetic contact is played by a spatially confined cavity polariton Bose-Einstein condensate. The condensate is responsible for the appearance of effective magnetic field which rotates the spin state of a propagating pulse of polaritons, allowing tuning the transmittivity of the device.
