Abstract :
The integration of the final three higher-speed functions of an electrooptical emitter in a single module - the multiplexer, the driver and the electroabsorption modulator (EAM) - is demonstrated. The module has operated up to a bit rate of 40 Gbit/s. The Mux-driver was made using in-house InP-double heterojunction bipolar transistor technology. The proposed solution has the following features: compactness, low bit rate inputs, no need of a bandpass capacitor or bias tee between driver and EAM, and possibility to adjust the driving offset voltage, electrical control output, low power consumption, etc
