The influence of an antireflection coating on the input-output power characteristics and the switch-on dynamics of a vertical-external-cavity surface-emitting laser is investigated numerically with an effective rate-equation simulation based on microscopic many-body calculations for the optical gain/absorption and carrier losses. The simulations show a significantly higher threshold and a slower switch-on dynamics for the antireflection coated devices. These differences are caused by a reduction in the mode amplitude at the position of the active medium due to a less pronounced subcavity.
