We present calculations of the carrier capture efficiency into various types of quantum well lasers. The carrier capture into a quantum well can be due to either optical phonon emission or carrier-carrier scattering. Both capture mechanisms have been calculated and show oscillations as a function of the quantum well thickness. By optimizing the carrier capture efficiency the carrier accumulation in the barrier layers can be reduced, resulting in an improved modulation response and threshold current.
