From: Squeezed-light-driven force detection with an optomechanical cavity in a Mach–Zehnder interferometer
(a) sPSD of \({\hat{F}}(\omega )\) as a function of scaled measurement strength \(G/\Omega ^3\) (red solid curve) along with the photon counting noise (blue dotted curve), radiation pressure backaction noise (black dot-dashed curve) and the standard quantum limit (gray dashed curve). (b) Standard quantum limit as a function of the scaled detection frequency. The parameters used are \(\kappa /\Omega = 10^2\), \(\Gamma /\Omega = 10^{-3}\).
