Abstract

A new effective /spl alpha/ parameter appropriate for evaluating the transmission performance of multiquantum-well electroabsorption (MQW-EA) modulators is proposed. It is defined by the ratio of the phase change to the loss change between the ON voltage and the voltage at which the exciton peak reaches the wavelength of the light source. Simulation reveals that along various effective /spl alpha/ parameters it has the best correlation with the equivalent /spl alpha/ parameter obtained from the transmission performance.<>
