Bistable nonlinear optical interfaces have potential advantages of lower absorption and higher switching speed over resonator-based bistable optical gates. The design of parallel vector multipliers based on all-optical logic gates on a nonlinear optical interface is proposed in this letter. These schemes can be extended to parallel multiplications of matrices and to photonic switching.
