ABSTRACT:
An interaction medium in which a photoinduced phase grating has been permanently recorded beforehand is coupled to the two ends of a monomode waveguide. A first wave which is a pulse travels through said waveguide and interferes with a second pumping wave in order to permit energy transfer from the second pumping wave to the first wave.
