Abstract :
An optical modulator driver IC and a preamplifier IC for 10 Gb/s optical communication systems are developed using AlGaAs/InGaAs/GaAs pseudomorphic two-dimensional electron gas (2DEG) FETs with a gate length of 0.35 μm. The optical modulator driver IC operates at a data rate up to 10 Gb/s with an output voltage swing of more than 4 Vp-p . The bandwidth for the amplifier IC is 13.0 GHZ with ab 47 dB-Ω transimpedance gain. In addition, optical transmission experiments with external optical modulation using these ICs have successfully been carried out at 10 Gb/s
