English, We demonstrate multiplication of two 8 bit binary words in less than 10 ps by generating two-pulse photon echo in a cryogenically-cooled polymer film doped with organic dye molecules. Input bits are coded in the intensity spectrum of 100 fs duration excitation pulses and the outcome of the multiplication is obtained by measuring the intensity spectrum of the photon echo signal. We study the dependence of the echo spectrum on the energy of the excitation pulses and investigate excitation conditions when the photon echo has maximum efficiency and minimum distortions.
