Paper Abstract

We report the evidence a novel phenomenon which is observed in VCSELs working in a bistable region, that we have called Noise Assisted Binary Information Transmission: the addition of noise to the pump current up to an optimal value leads to a strong improvement of the transmission quality, measured by the Bit Error Rate. We analyze different indicators to define the output string and the comparison of the input with the output signal is eventually reduced to a comparison of binary strings and can treated by means of standard methods of information theory. These results represent the first experimental evidence of Aperiodic Stochastic Resonance. We analyze the possible application to optical communications and compare it to a standard amplitude modulation scheme.
