TLDR
The first observation of stochastic resonance in an optical device, the bidirectional ring laser, is reported and the addition of injected noise can lead to an improved signal-to-noise ratio.Abstract:
We report the first observation of stochastic resonance in an optical device, the bidirectional ring laser. The experiment exploits a new technique to modulate periodically the asymmetry between the two counter-rotating lasing modes. The measurements verify that the addition of injected noise can lead to an improved signal-to-noise ratio (relative to that observed with no externally injected noise).read more

Stochastic resonance in the brain
Toshio Mori,Shoichi Kai +1 more
TL;DR: In this article, the authors investigated the existence of stochastic resonance (SR) in the human brain, based on the noise effect of the α-wave and found that strong entrainment occurs for a certain range of the noise amplitude.

Stochastic Resonance in Linear Region of a Single-Mode Laser: Effects of Amplitude Modulation of Signal
TL;DR: In this article, a single-mode laser noise model driven by quadratic colored pump noise and amplitude modulation signal is proposed, where real and imaginary parts of the pump noise are assumed to be cross-correlation.

On the Theory of Stochastic Resonance
TL;DR: In this paper, the phase amplitude and phase frequency dependences for a weak periodic signal at the output of a bistable system were derived for low noise intensity as compared to the potential-barrier height.

Stochastic resonance in a bistable system driven by cross-correlated noises and an amplitude modulation signal
TL;DR: In this paper, a stochastic resonance effect in a bistable system driven by an amplitude modulation (two-frequencies) signal and cross-correlated additive and multiplicative noises is explored.

Noise correlation-induced splitting of Kramers' escape rate from a metastable state
TL;DR: In this paper, a correlation between two noise processes driving the thermally activated particles in a symmetric triple well potential, may cause a symmetry breaking and a difference in relative stability of the two side wells with respect to the middle one.
