Abstract
A process for the transposition of a modulation of an adjustable wavelength. A semiconductor amplifier is relooped through a feedback loop including a filter set to a first wavelength. An incident beam set at a second wavelength which is amplitude modulated is injected into the semiconductor amplifier laser. The incident beam is either extinguished or allows self-oscillation to be established in the loop. Thus, the modulation is transposed from the second wavelength to the first wavelength.
