Abstract: A novel kind of aperiodic stochastic resonance is experimentally studied in a vertical cavity surface emitting laser We characterize the response of the system to a random, binary signal as a function of an applied external noise. A maximum in the input-output correlation is found for a nonzero added noise. We present analytic results with a good agreement with the measurements. We also discuss the physical meaning of the phenomenon using simple arguments, and we compare it to stochastic resonance.
