Query: Stable Optical Phase Modulation with Micromirrors   We measure the motional fluctuations of a micromechanical mirror using a
Michelson interferometer, and demonstrate its interferometric stability. The
position stability of the micromirror is dominated by the thermal mechanical
noise of the structure. With this level of stability, we utilize the
micromirror to realize an ideal optical phase modulator by simply reflecting
light off the mirror and modulating its position. The resonant frequency of the
modulator can be tuned by applying a voltage between the mirror and an
underlying electrode. Full modulation depth of +/-\pi is achieved when the
mirror resonantly excited with a sinusoidal voltage at an amplitude of 11V.
