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, characterised in that it is apt to simultaneously generate and process Nc >= 2, made of C chips with time interval tau, with C>= 2, characterised in that the transfer function Tsk (f) from the input s to the output k satisfies the following formula: where: Fv is a transfer function of an optical filter, for v=0,1..., V-1, av is a constant value, for v=0,1,..., V-1 Ssk is an integer number (Ssk ϵ Z), Nk is a constante value, for k=2,...N, and V is a positive integer number with 1<=V&LE;LOG2N. 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. |
