Abstract
Techniques are described for data transfer in spin-based systems where digital bit values are represented by magnetization states of magnetoresistive devices rather than voltages or currents. For data transmission, a spin-based signal is converted to an optical signal and transmitted via an optical transport. For data reception, the optical signal is received via the optical transport and converted back to a spin-based signal. Such data transfer may not require an intervening conversion of the spin-based signal to charge-based signal that relies on voltages or currents to represent digital bit values. In addition, techniques are described to use magnetoresistive devices to control the amount of current or voltage that is delivered, where the magnetization state of the magnetoresistive device is set by an optical signal.
