Optical transmitter comprising a modulator made of a plurality of modulating elements

The optical transmitter (100) comprises an electro-optic modulator (30) controlled by an electronic control circuit (50). The modulation elements (MN) may be electro-absorption modulators or discrete Mach-Zender modulators. The optical elements are connected optically in series. The optical transmit...

Zusammenfassung:The optical transmitter (100) comprises an electro-optic modulator (30) controlled by an electronic control circuit (50). The modulation elements (MN) may be electro-absorption modulators or discrete Mach-Zender modulators. The optical elements are connected optically in series. The optical transmitter (100) comprises an electro-optic modulator (30) controlled by an electronic control circuit (50). The modulator (30) comprises N modulation elements (MN), with N distinct control electrodes optically coupled in series. The electronic control circuit (50) is designed to deliver N identical electrical signals (Q) on N distinct outputs. Each of the N outputs is connected respectively to each of the N electrodes for control of the modulation elements (MN). The modulation elements (MN) may be electro-absorption modulators or discrete Mach-Zender modulators. The electronic control circuit may be a multiplexer with synchronised outputs, or an amplifier with synchronised outputs.
