Optical transmission system with encryption on the basis of deterministic chaos

摘要

System for the transmission of an optical signal carrying information, comprising means (3) for the generation of a deterministic chaos, as well as means for the coding of the signal carrying information, for this deterministic chaos, the chaos being a wavelength chaos, said means (3) for generating chaos comprising a light source that is tunable in wavelength (33), as well as a loop (34) of the other hand, - reaction of the light signal at the output of said source on the control of the wavelength tuning, the loop (34) comprising means (32) of conversion of the non-linear of the wave length, as well as a delay line (31).
