Abstract :
Summary form only given. Recently, Pikovsky and Kurts studied the effect of noise in fluctuations of the time between successive excitable pulses are minimized for a well-defined amount of the input noise. They named such a behavior coherence resonance. We present an experimental investigation of the effects of noise in an excitable optical system, namely, a semiconductor laser with optical feedback. Changing the amount of noise, and choosing the adequate indicators, we report experimental evidence of coherence resonance.
