摘要： An optical logic apparatus includes a plurality of logic elements on a single passive, nonlinear Fabry-Perot etalon characterized by a shift in transmissivity in response to increased incident light, a source producing a probe beam having a first wavelength which does not significantly modify the index or refraction of the nonlinear medium, and a plurality of sources of input beams each representing a respective logic signal. The input beams all have a wavelength which significantly modifier the index of refraction of the nonlinear medium. The probe beams illuminate the surface of the etalon. The input beams are mapped by a lens onto the etalon, which produces a plurality of output beams each representing various logical functions of the input beams, which logical functions are determined by the frequency of the various probe beams. The output beams become input beams which are optically mapped, in combination with additional probe beams, onto a second etalon. The outputs of the second etalon can be similarly mapped onto further etalons or into the first etalon.
