Determination of the optimum frequency response in directly modulated diode lasers

Abstract EN

In order to determine the optimum frequency response in direct modulation diode lasers, the nonlinear rate equations of directly modulated diode laser must be solved (numerical solution).

The rate equations describe the dynamic behavior of semiconductor laser since the optical field depends on time.

On the other hand, the rate equations describe the interactions among photon density, carrier density, and the phase of photon .However, these equations are used to predict the nonlinear distortions appeared in the performance of directly modulated semiconductor laser.
