Abstract
Analytic expressions for carrier capture and escape currents into quantum wells are derived. The authors find that the escape rate can be as large as the capture rate under typical operating conditions in quantum-well lasers so that the damping and inertia of the relaxation oscillation are significantly increased in these lasers. Implications for the limitation of the modulation bandwidth of quantum-well lasers and its dependence on the quantum-well structure are discussed.<>
