We present the optimization of multiple-quantum-well (MQW) electroabsorption (EA) modulators based on system transmission performance simulation. The absorption spectra of InGaAsP MQW material under different electric fields are worked out using a non-variational numerical method. Transmission simulation is then carried out using the calculated extinction ratios and chirping parameters to evaluate the performance of the EA modulator under a predefined operation condition. Voltage-dependent chirping parameters are adopted to offer a more realistic description of the performance of the EA modulator in actual fiber communication systems. Simulation results show that the barrier bandgap wavelength and the well width have the most significant influence on device performances.
