Abstract: Using an optical cavity, coupled to a micromechanical oscillator - a relatively heavy mass, double trampoline resonator - we will test whether we can, using the method proposed by Clerk et al. (2008), perform back-action evading measurements (BAE) in the optical domain on a single quadrature of the oscillator’s motion. We will do so by probing the oscillators motion with two optical drives spaced one mechanical resonance frequency above and below the cavity resonance frequency. We will then inject noise in the cavity and analyze the light leaving the cavity. This is intended to show that we can perform classical back-action evading measurements. The long term goal of this project is to find out if this system is capable of reaching or exceeding the standard quantum limit (SQL).
