    "abstract": "We show that anomalous dispersion characteristic of fast-light can be used to\nenhance the sensitivity of optical interferometry under certain conditions. In\nparticular, we show that a dual-chamber Fabry-Perot interferometer with a\nshared mirror-pair can be used in a way so that its sensitivity is increased by\noperating near the critically anomalous dispersion condition where the group\nindex is much less than unity. The enhancement factor can be as high as 108 for\nrealistic conditions. The process of bi-frequency pumped Raman gain in a\nlambda-type atomic medium can be used to achieve this effect.",
