A system includes an emitter unit that generates random numbers encoded in light polarization, and a detector unit positioned with respect to the emitter. The detector receives the random numbers from the emitter and converts them into an electrical signal. The emitter unit can include a substrate; a bottom electrically conductive and optically reflective layer outward of the substrate; an active medium layer, outward of the bottom layer, configured to convert spin information carried by injected spin-polarized electrical carriers into light polarization information carried by light emitted from radiative recombination of the electrical carriers; a top electrically conductive and optically reflective layer outward of the active medium layer; a bottom electrically conductive contact electrically interconnected with the bottom layer; a top electrically conductive contact electrically interconnected with the top layer; and an electrically conductive carrier spin-polarizer layer located between, and electrically interconnected with, the bottom layer and the bottom contact.
