Paper Abstract

This paper presents an extrinsic Mach-Zehnder type accelerometer that utilizes a gap between a fiber cantilever and a fixed fiber. The problem of light insertion to the single mode fiber across the gap is eased with the use of quarter pitch GRIN lenses. Phase feedback is done through the laser diode in conjunction with active homodyne demodulation. The accelerometer has a dynamic range of 84 dB and a resolution of 10-4 g. The configuration uses all-fiber components that are readily transferable to the integrated optic domain.
