Abstract
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.
