Abstract
A theory of acoustic scattering of light in a Fabry-Perot resonator is described. The theory predicts the optimum acoustic scattering frequencies, the acoustic bandwidth, and the scattering enhancements as a function of the cavity geometry. The calculation is based on the formalism developed by Gordon and Rigden for the Fabry-Perot Electro-optic Modulator. Experiments are discussed which yield results in excellent agreement with the theory. Acoustic phase velocities can be determined to 4-place accuracy. The experiments illustrate that narrow-band modulators (∼ 10 mc/s) can be made to produce 100% amplitude modulation with acoustic powers less than 50 milliwatts.
