Abstract
Electro-optical modulator (), comprising at least one electrical port () and an input circuit () for the application of a modulating electrical signal to the said at least one electrical port. The said modulator also comprises a linear processing circuit () capable of generating a compensation signal. This linear processing circuit comprises a first terminal connected to the input circuit for taking a fraction of the said modulating electrical signal, at least one filtering element () for eliminating predetermined spectral components from the said fraction of the modulating electrical signal, and at least one phase-shifting element () for inverting the phase of the said fraction of the modulating electrical signal. The said linear processing circuit also comprises a second terminal capable of being connected to the said at least one electrical port for applying the compensation signal to the said electro-optical modulator.
