We address the problem of the stability of a cavity optomechanical system based on an oscillator having at the same time low optical and mechanical losses. As we are interested in extending the use of optical squeezing as a tool for improving quantum limited displacement sensing at low frequency, we have developed a family of opto-mechanical devices designed to work at frequencies of about 100 kHz. The devices actually meet the initial design goals, but new requirements have emerged from the analysis of their behavior in optical cavities, due to the interaction between the cavity locking system and the low order normal modes of the devices.

Abstract

We address the problem of the stability of a cavity optomechanical system based on an oscillator having at the same time low optical and mechanical losses. As we are interested in extending the use of optical squeezing as a tool for improving quantum limited displacement sensing at low frequency, we have developed a family of opto-mechanical devices designed to work at frequencies of about 100 kHz. The devices actually meet the initial design goals, but new requirements have emerged from the analysis of their behavior in optical cavities, due to the interaction between the cavity locking system and the low order normal modes of the devices.
