Abstract
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≧2, made of C chips with time interval τ, with C≧2, characterized in that the transfer function T(f) from the input s to the output k satisfies the following formula: where: Fis a transfer function of an optical filter, for v=0, 1 . . . , V−1, ais a constant value, for v=0, 1, . . . , V−1 Sis an integer number (SεZ), Nis a constant value, for k=2, . . . N, and V is a positive integer number with 1≧V≧logN. 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.
