Experimental evidence of vibrational resonance in a multistable system

Abstract

Experimental evidence of vibrational resonance in a multistable vertical-cavity surface-emitting laser (VCSEL) is reported. The VCSEL is characterized by a coexistence of four polarization states and driven by low-frequency (LF) and high-frequency (HF) periodic signals. In these conditions a series of resonances on the low frequency depending on the HF amplitude is observed. The location of resonances in a parameter space (dc current, amplitude of HF signal) is experimentally studied. For a fixed value of the dc current an evolution of the resonance curves with an increase of the LF amplitude is experimentally investigated.

Analysis of vibrational resonance in bi-harmonically driven plasma

“…5, rather Q shows several spikes, indicating that the system is in a chaotic state. The emphasis here is that beside the role of the system's effective potential (16), the effective nonlinear dissipation, γ of the system plays a critical contributory role in the occurrence of VR in this plasma model. Remarkably, the enhancement of signal by means of VR in plasma is particularly significant with a given set of carefully chosen low-dissipation.…”

“…A comprehensive analytical procedure on VR of bistable Duffing oscillator which established its effective stiffness was carried out by Blekhman and Landa 11 and generalized in a book by Blekhman 12 . Since then, vibrational resonance has attracted a lot of attentions in bistable systems 2,11,13 , multistable systems [14][15][16] , excitable systems 17 , ratchets 18 , quintic oscillators 19 , overdamped systems 2,15,18 , coupled oscillators 15,20 , delayed systems 15,[20][21][22] , assymetric Duffing oscillators 23 , fractional order damped oscillators 24 , feedback networks 25 , neuron models 17,[26][27][28] , synthetic gene network 29 and biological nonlinear maps 30 . Moreover, experimental evidences of vibrational resonance has also been reported, notably in bistable and multistable verticalcavity surface-emitting laser (VCSEL) 13,16,31 .…”

Vibrational higher-order resonances in an overdamped bistable system with biharmonic excitation

“…Experiments were performed on the experimental setup recently used for studying VR in a multistable VCSEL [24]. A 850 nm VCSEL (Honeywell HFE4080-321) with a threshold current J th ≈ 5.6 mA was used in the experiments.…”

Vibrational resonance in an inhomogeneous medium with periodic dissipation

“…In what follows, we will focus on a form of vibrational resonance (VR). In systems with linear damping, VR has already been widely investigated [38][39][40][41][42][43][44][45] following an early study by Landa and McClintock [36]. The results have shed light on the contributions to the effective potential of the various components of the high frequency signal [27], as well as the roles played by system parameters such as delay and fractional order terms in the induction, enhancement and control of VR [46][47][48][48][49][50][51].…”
