Fig. 5: Optical resonance for bulk acoustic wave (BAW) resonator inside Fabry–Perot cavity.

From: Gravitational wave detectors with broadband high frequency sensitivity

Fig. 5

The cavity optical frequency ω and thickness q of the BAW resonator are plotted using the shift from their respective initial values ω0 and q0. The curves represent four selected optical modes, which are separated by the sinusoidally varying free spectral range of the cavity.
