From: Squeezed-light-driven force detection with an optomechanical cavity in a Mach–Zehnder interferometer

Optimum squeezing direction as a function of the scaled detection frequency at the optimum measurement strength (a) across the low frequency regime and (b) enlarged in the vicinity of the mechanical resonance. The parameters used are \(\kappa /\Omega = 10^2\), \(\Gamma /\Omega = 10^{-3}\).
