    "abstract": "We discuss a phase-sensitive technique for remote interrogation of passive\nBragg grating Fabry-Perot resonators. It is based on Pound-Drever-Hall laser\nfrequency locking, using radio-frequency phase modulation sidebands to derive\nan error signal from the complex optical response, near resonance, of a\nFabry-Perot interferometer. We examine how modulation frequency and resonance\nbandwidth affect this error signal. Experimental results are presented that\ndemonstrate when the laser is locked, this method detects differential phase\nshifts in the optical carrier relative to its sidebands, due to minute fiber\noptical path displacements.",
