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

Noise-induced jumps in two coupled Duffing oscillators
TL;DR: In this paper, two coupled Duffing oscillators with the coexistence of four attractors were investigated and three types of noises such as Gaussian, amplitude dependent and dichotomous were used.

Nonlinear stochastic effects during the action of noise on relaxation oscillations in a ring solid-state laser
TL;DR: In this paper, the influence of pump noise intensity on the characteristics of the fundamental relaxation frequency of the emission spectrum of a ring chip laser operating in the self-modulation regime of the first kind is studied theoretically and experimentally.

TL;DR: The possibility of a proactive role for consciousness in the establishment of physical reality has been addressed via an extensive 26-year program investigating physical anomalies in human/machine interactions and non-sensory acquisition of information about remote geographical locations.

Signal amplification in NbN superconducting resonators via stochastic resonance
TL;DR: In this article, the authors exploit nonlinearity in NbN superconducting stripline resonators, which originates from local thermal instability, for studying stochastic resonance.

Information length as a new diagnostic in the periodically modulated double-well model of stochastic resonance
TL;DR: In this paper, the authors considered the double-well model of stochastic resonance and provided direct numerical solutions of the Fokker-Planck equation for the probability density function p ( x, t ) for ω = 1 0 − 2 to 1 0−6, and A ∈ [ 0, 0. 2 ].
