Abstract
A process for a simultaneous optical modulation transposition on several wavelengths. Use is made of a semiconductor laser able to freely oscillate on several longitudinal modes, the semiconductor laser being able to lock on a wavelength of an incident optical beam. The modulation is transposed on the modes which are not at the wavelength of the incident optical beam. Such a process may find particular application in optical telecommunication systems.
