Majority logic device, photoelectric conversion device, optical communication logic device and method for controlling majority logic device

A method of controlling a majority logic device,

• wherein the majority logic device comprises a nonmagnetic semiconductor layer comprising a material which, upon irradiation of light having at least two mutually different polarization states, generates electron spin waves having different phases depending on the polarization states,
• wherein the nonmagnetic semiconductor layer comprises three or more input sections for inputting optical signals and at least one output section for outputting the result of interference of the electron spin waves,
• wherein the deviation of the length of the projection of the distance between adjacent input sections in the oscillating direction of the electron spin wave from an integer multiple of the wavelength of the electron spin wave is within 25% of the wavelength and
• wherein the optical signals are optical signals modulated with right-handed circularly polarized light and left-handed circularly polarized light.

A majority logic device, comprising:

• a two-dimensional wire structure in which three or more odd one-dimensional fine wire structures for signal input meet at a single junction point,
• wherein each of the one-dimensional fine wire structures for signal input has a nonmagnetic semiconductor layer comprising a material which, upon irradiation of light having at least two mutually different polarization states, generates electron spin waves having different phases depending on the polarization states,
• wherein each of the one-dimensional fine wire structures for signal input has an input section for inputting optical signals before the junction point,
• wherein the junction point comprises an output section which outputs the result of interference of the electron spin waves at the junction point and
• wherein the deviation of the length of the projection of the distance between the junction point and the respective input sections of the one-dimensional fine wire structure for signal input in the oscillating direction of the electron spin wave from an integer multiple of the wavelength of the electron spin wave is within 25% of the wavelength.
