摘要：

The usefulness and the limitations of the concept of the linewidth enhancement factor a in semiconductor lasers are examined by considering the laser dynamics without the rate-equation approximation. The rate equations with a constant value of alpha can be used for semiconductor lasers operating continuously or modulated directly such that the carrier density does not change significantly during each modulation cycle. A new set of generalized Bloch equations should be used whenever subpicosecond optical pulses are involved.
