摘要：
An extended model for the calculation of alpha(eff) is presented including for the first time the carrier dynamics in the absorptive grating. It is shown that for comparable carrier lifetime in the absorptive and active regions a significant reduction of alpha(eff) may be achieved by the antiphase configuration of the complex coupling coefficient.
