Abstract
An optical modulator includes an optical waveguide and an electrode structure coupled to the waveguide such that a modulating signal applied to the electrode structure varies the refractive index of the waveguide so as to produce a modulated optical output signal. The electrode is fabricated in the form of a transmission line terminated in a short circuit. The ratio of the wavelength of the modulating signal to the effective length of the electrode is comprised between 2.1 and 4.0, and is preferably of approximately 2.7. The modulator can be constructed to provide either phase or amplitude modulation. An optical transmission method having SBS suppression and an optical modulator system are further provided.
