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).

Stochastic resonance induced by a multiplicative periodic signal in a bistable system with cross-correlated noises and time delay

TL;DR: In this paper, the authors studied the stochastic resonance (SR) phenomenon induced by a multiplicative periodic signal in a bistable system with cross-correlated noises and time delay.

Adding noise to improve measurement

TL;DR: Stochastic resonance can reduce threshold while suitable noise modulation can linearize thresholds and improve the performance of several system classes in the presence of noise.

Effects of time delay and random rewiring on the stochastic resonance in excitable small-world neuronal networks

TL;DR: It is argued that the time delay and the rewiring probability both play a key role in determining the ability of the small-world neuronal network to improve the noise-induced outreach of the localized subthreshold pacemaker.

Stochastic resonance in periodic potentials driven by colored noise

TL;DR: In this paper, the authors studied the motion of an underdamped Brownian particle in a periodic potential subject to a harmonic excitation and a colored noise, and calculated the average input energy per period and the phase lag to quantify the phenomenon of stochastic resonance (SR).

Is electrical noise useful? [Point of View]

TL;DR: The proposition that electrical noise could be useful is anathema to the designers of electronics and communication systems, who usually have a mission to eradicate as much noise as possible, so one needs to look outside the parameters of conventional assumptions and perspectives for situations where electrical noise can be useful.
