Abstract-- We build upon and derive a precise far from carrier
phase noise model for radiation pressure driven opto-mechanical
oscillators and show that calculations based on our model
accurately match published phase noise data for such oscillators.
Furthermore, we derive insights based on the equations presented
and calculate phase noise for an array of coupled disk resonators,
showing that it is possible to achieve phase noise as low as -80
dBc/Hz at 1 kHz offset for a 54 MHz opto-mechanical oscillator.
