  • Electro-optical element for generating an amplitude-modulated optical signal, in particular electro-absorption modulator
    Publication number: 20040264978
    Abstract: The present invention discloses an electro-optical element and a method for generating an amplitude-modulated optical signal (24). The element comprises a semiconductor substrate (12), an electro-optical modulation structure arranged on the substrate (12), a first terminal (22) for supplying an optical signal (20) to be modulated, a second terminal (28) for supplying an electrical modulation signal, and a modulation area adapted for modulating the optical signal (20) with the electrical modulation signal (50). According to one aspect of the invention, a limiter (30) is provided for limiting the electrical modulation signal. The limiter (30) is arranged on the substrate (12) and is operatively connected between a second terminal (28) and the modulation area.
