Abstract
A method for frequency-converting a source optical signal in order to produce a useful optical signal, by mixing a plurality of waves, implements a plurality of waveguides that are coupled together. Individual parameter values of the waveguides, as well as at least one coupling parameter, are selected so as to obtain the useful signal with a high intensity. Such a method for producing the useful signal is suitable for a spectroscopic application, in particular a molecular spectroscopy application.
