The pressure sensitivity of the phase of light propagating in aluminum-coated fibers is studied both analytically and experimentally. The analytically predicted reduction in fiber sensitivity that is due to the balancing of pressure-induced length changes with strain-induced index changes is demonstrated experimentally.
