The invention relates to an optical device, apt to generate and process optical codes at least one wavelength, comprising P inputs s, with 1<=s<=P, and P>=1, and N outputs k, with 1<=k<=N and N>=1, characterized in that it is apt to simultaneously generate and process N<SUB>c</SUB>>=2, made of C chips with time interval tau, with C>=2, characterized in that the transfer function T<SUB>sk</SUB>(f) from the input s to the output k satisfies the following formula: where: F<SUB>v </SUB>is a transfer function of an optical filter, for v=0, 1 . . . , V-1, a<SUB>v </SUB>is a constant value, for v=0, 1, . . . , V-1 S<SUB>sk </SUB>is an integer number (S<SUB>sk</SUB>epsilonZ), N<SUB>k </SUB>is a constant value, for k=2, . . . N, and V is a positive integer number with 1>=V>=log<SUB>2</SUB>N. The invention further relates to a set of optical codes, apt to be generated, in particular, by such optical device, and to networks and apparatus comprising such optical device. |
