    "abstract": "We present a method for remote interrogation of passive fiber Bragg grating\nFabry-Perot resonators, employing current modulation of the diode laser source.\nWith the presence of both RF amplitude and frequency modulation, it is a\nvariant of the ultra-sensitive Pound-Drever-Hall laser frequency locking\ntechnique. We demonstrate that current modulation and interferometric\ndemodulation removes the need for a phase modulator in the sensing\narchitecture.",
