Title:
光コードを同時に生成および処理する光デバイス
Document Type and Number:
Japanese Patent JP2007528503
Kind Code:
A
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 Nc>=2, made of C chips with time interval tau, with C>=2, characterized 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 (SskepsilonZ), Nk is a constant value, for k=2, . . . N, and V is a positive integer number with 1>=V>=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.
