摘要：

We investigate theoretically the chaotic dynamics in an optomechanical system composed of coupled optical resonators. We find that introducing additional loss through a nanotip can induce chaotic motion. The underlying reason for this unconventional phenomenon lies in steering the system parameters via an additional loss that can bring the system to the vicinity of a chaotic regime, which dynamically enhances the optomechanical nonlinearity and suppresses the negative influence of loss, giving rise to the emergence of chaotic motion. Our work may open a different avenue for designing and developing chaotic systems in optomechanics and provide theoretical guidance for chaotic secure communication.
