Abstract

We realized a logical function of bit-to-bit parallel multiplication for optical echo-processor based on the third-order nonlinear optical response of a resonant medium at room temperature. As an operating medium we used the polyvinilbutural film doped with phthalocyanine dye. The result of the logical operation is presented in the spectrum of the nonlinear optical response after action of the two spectrally coded pumping pulses. The time of the logical operation is about 500 fs. We obtained the values of a homogeneous broadening of S₀ - S₁ line: Γ_hom = 89 cm^-1 at T = 300 K and Γ_hom = 44 cm^-1 at T = 77 K. The laser excitation parameters needed for effective operating of optical processor are defined. The maximum word length achievable under current experimental conditions is estimated.
