Andrey A. Rakhubovsky, Sergey P. Vyatchanin
TL;DR
This paper analyzes how detuned laser pumping in a Fabry-Perot interferometer creates optomechanical eigenmodes that can be squeezed via parametric modulation, with observable effects in the reflected light.
Contribution
It introduces a detailed analysis of optomechanical eigenmodes in a detuned Fabry-Perot cavity and demonstrates noise squeezing through laser power modulation.
Findings
Eigenmodes act as high-Q oscillators
Laser power modulation enables quadrature squeezing
Squeezing effects are observable in reflected light
Abstract
We carry out analysis of optomechanical system formed by moveable mirror of Fabry-Perot cavity pumped by detuned laser. Optical spring arising from detuned pump creates in the system several eigen modes which could be treated as high-Q oscillators. Modulation of laser power results in parametric modulation of oscillators spring constants thus allowing to squeeze noise in quadratures of the modes. Evidence of the squeezing could be found in the light reflected from the cavity.
