Abstract
An a system and method for chaos transfer between multiple detuned signals in a resonator mediated by chaotic mechanical oscillation induced stochastic resonance where at least one signal is strong and where at least one signal is weak and where the strong and weak signal follow the same route, from periodic oscillations to quasi-periodic and finally to chaotic oscillations, as the strong signal power is increased.

A method for chaos transfer between multiple signals comprising:
- transmitting multiple detuned signals in an optical micro cavity resonator with optomechanically induced oscillation where at least one signal is stronger than and detuned with respect to at least one other signal;
- and
- increasing the power of the at least one signal whereby as the power is increased the at least one signal and the at least one other signal follow the same route, from periodic oscillations to quasi-periodic and finally to chaotic oscillations.
A system demonstrating chaos transfer between multiple signals comprising:
- a first signal generator configured to transmit a first signal through an optical micro cavity resonator;
- a second signal generator configured to transmit a second signal through the optical micro cavity resonator where the second signal generator is configured to transmit said second signal that is weaker than the first signal and second signal is detuned with respect to the first signal;
- and
- a photo detector and spectral analyzer configured to detect the transmitted light and calculating a maximal Lyapunov exponent of the first and second signals.
A method for chaos transfer between multiple signals comprising:
- transferring chaos on an optical field in a microcavity resonator to a weaker optical signal in the same microcavity resonator, the chaos induced by optomechanical oscillations, and said weaker optical signal is detuned from an optical resonance of the microcavity resonator in their optical frequencies and/or wavelengths by selectively tuning the signals such that their frequency is detuned from the optical resonance of the resonator by the frequency of the mechanical frequency which is excited by the optical field.
A method comprising:
- steering a waveguide-coupled microresonator to its exceptional point (EP);
- controlling the chirality of the light circulating in the microresonator thereby controlling the emission direction of a microlaser;
- and
- tuning the microresonator from an EP to another EP, such that the emission direction of the laser is be tuned from a unidirectional emission in the clockwise direction to a unidirectional emission in the counter-clockwise direction.
