Theory 04/Optomechanics
Squeezing Bandwidth Is a Coupling Ratio
The claim
The bandwidth over which a mechanical oscillator can be squeezed is set by the ratio of optomechanical coupling to cavity decay rate rather than by coupling alone.
01The mechanism
Squeezing requires correlations to build within the cavity lifetime; the ratio sets how much correlation survives before decay erases it.
02Predictions
- P1Bandwidth should track the coupling ratio.
- P2Strong coupling with fast decay should not broaden bandwidth.
03Refutation
Bandwidth tracking absolute coupling would remove the ratio.
