Enhancing the sensitivity of interferometer by the way of slow light

Recent years, the technology of slow light generations and applications are becoming hot topics, including data buffering in optical communications and optical signal delay. In this paper, we propose the application of slow light in the field of optical sensor and illustrate several principles and structures to enhance the sensitivity of interferometers based on slow light. According to the experiment results, the sensitivity of the interferometers enhance 600 times at most; however, the sensitivity can enhance 107 times in theory; moreover, the volume of the interferometer can be reduced. The miniaturization and precision devices must be applied and researched deeply in the field of sensor and measurement technology.
