Cavity Optomechanical Magnetometer
S. Forstner, S. Prams, J. Knittel +6
A cavity optomechanical magnetometer is demonstrated where the magnetic field induced expansion of a magnetostrictive material is transduced onto the physical structure of a highly…
Feedback Enhanced Sensitivity in Optomechanics: Surpassing the Parametric Instability Barrier
Glen I. Harris, Ulrik L. Andersen, Joachim Knittel +1
The intracavity power, and hence sensitivity, of optomechanical sensors is commonly limited by parametric instability. Here we characterize the parametric instability induced sensi…
Mechanical squeezing via parametric amplification and weak measurement
Alex Szorkovszky, Andrew C. Doherty, Glen I. Harris +1
Nonlinear forces allow motion of a mechanical oscillator to be squeezed below the zero-point motion. Of existing methods, mechanical parametric amplification is relatively accessib…
