We experimentally study the dynamics of a Vertical Cavity-Surface Emitting Laser (VCSEL) with an injected signal subject to an external perturbation, in excitable regime. The possibility to control the kind of response of the system, depending on the perturbation amplitude, is demonstrated. Our perturbation technique induces excitable pulse with 100% efficiency when perturbation is above threshold.
