All-Optical Brillouin Random number Generator
A. R. Mukhamedyanov, E. S. Andrianov, A. A. Zyablovsky
We propose a model of binary random number generator (RNG) based on a Brillouin optomechanical system. The device uses a hard excitation mode in a Brillouin optomechanical system,…
A control of threshold of hard excitaion mode of optomechanical system by a low-intensity seed wave
Artem. R. Mukhamedyanov, Evgeny S. Andrianov, Alexander A. Zyablovsky
An optomechanical system based on two optical modes, one of which is pumped by a coherent wave, interacting with each other via a phonon mode is considered. In such a system, a har…
Spontaneous PT-symmetry breaking transitions under the influence of noise in an optomechanical system
A. R. Mukhamedyanov, E. S. Andrianov, A. A. Zyablovsky
Spontaneous symmetry breaking is a phenomenon of an alteration of a state symmetry without a change in the system symmetry. A transition from a state with unbroken symmetry to a st…
Non-monotonic dependence of the radiation linewidth in a phonon laser
A. R. Mukhamedyanov, E. S. Andrianov, A. A. Zyablovsky
A phonon laser is an important device that can generate coherent sound waves at gigahertz frequency. In this paper, we demonstrate that in a phonon laser, the radiation line width…
Hard excitation mode of system with optomechanical instability
Artem Mukhamedyanov, Alexander A. Zyablovsky, Evgeny S. Andrianov
System with strong photon-phonon interaction and optomechanical instability are perspective for generation of coherent phonons and photons. Typically, above the threshold of optome…
