Integrated optoelectronic device comprising an electroabsorption modulator and an electronic element for controlling the modulator
First Claim
1. An integrated optoelectronic device (100) comprising:
- an electroabsorption modulator (10) suitable for delivering an output modulated optical signal (Sf) carrying data; and
an electronic control element (20) suitable for driving said modulator;
the device being characterized in that the modulator (10) comprises a plurality of optically coupled modulation sections (11, 12, 13) each having a respective electrode (1, 2, 3), each of said modulation sections being suitable for receiving an optical signal delivered by the adjacent modulation section disposed upstream in the light propagation direction (Z); and
in that the electronic control element (20) comprises;
distributed electrical amplifier means (22, 23, 24) suitable for delivering to each of said modulation sections a respective “
control”
amplified modulated electrical signal (V1, V2, V3); and
an electrical propagation line (21) for said control signals, which line is provided with a plurality of segments, some of which are “
electrode”
segments and correspond to said electrodes (1, 2, 3).

Abstract
The present invention relates to an integrated optoelectronic device (100) comprising an electroabsorption modulator (10) suitable for delivering an output modulated optical signal (Sf) carrying data, and an electronic control element (20) suitable for driving said modulator. The modulator (10) comprises a plurality of modulation sections (11, 12, 13) that are optically coupled together, each having a respective electrode (1, 2, 3), each of said modulation sections being suitable for receiving an optical signal delivered by the adjacent modulation section disposed upstream in the light propagation direction (Z). The electronic control element (20) comprises distributed electrical amplifier means (22, 23, 24) suitable for delivering to each of said modulation sections an amplified modulated electrical “control” signal (V1, V2, V3), and an electrical propagation line (21) for said control signals which is provided with a plurality of segments, some of which are “electrode” segments corresponding to said electrodes (1, 2, 3).
