Abstract. A many-body theory, based on the solutions of generalized semiconductor Maxwell-Bloch equations for coupled-band multiple quantum wells is applied to the description of the optical non linearities responsible for the operation of a resonator as a logical device. The numerical simulation of a NOR gate is in good agreement with experimental realizations.

Keywords: optical computing, many-body effects, optical nonlinearities, semiconductor quantum wells.
