ABSTRACT:
A radiant energy logic element includes first and second reflecting devices and a radiant energy nonlinear medium between said first and second reflecting devices and in contact therewith. Radiant energy beams of first and second wavelengths are applied to the reflecting devices. The first reflecting device is transmissive at said second radiant energy beam wavelength and reflective at said first radiant energy beam wavelength, and said second reflecting device is reflective at said first and second radiant energy beam wavelengths. The nonlinear medium of the logic element is responsive to radiant energy beams applied to the first reflecting device but insensitive to radiant energy beams applied to the second reflecting device.
