Sensitivity Improvement of Optical Interferometer Based on Controllable Group Velocity
In order to enhance the sensitivity of an optical interferometer, we deduce the relation between the group refractive index and the optical sensitivity of the interferometer by using slow or fast light material. The relation demonstrates that high optical sensitivity of an interferometer can be got by using fast light material. Under the condition of slow light, absorption area of corresponding material does harm to to weak signal detection, but the condition of fast light benefits weak signal detection.
