Abstract

We investigate the optical properties of Ⅲ-Ⅴ and Ⅱ-Ⅵ semiconductors. The results show that the sensitivity of the interferometer can be greatly enhanced by the dispersive property of semiconductor. Furthermore, the analyses show that the semiconductor slow light medium has a more wider working spectral range than gas slow light medium. Moreover, we experimentally demonstrate that the sensitivity of the interferometer based on the semiconductor GaAs is 3.2 times higher than those of traditional interferometers.

A novel interferometer is designed based on the dispersive property of slow light media. The numerical simulation on its physical process proves that the spectral sensitivity of interferometer can be enhanced effectively using the slow light medium. And the sensitivity is proportional to the group refractive index of the slow light medium. A further investigation gives the general method of designing slow light interferometers taking into account the dispersive property of GaAs. It is theoretically demonstrated that the spectral sensitivity of an interferometer can be greatly enhanced by dispersive property of semiconductor GaAs in nearinfrared region.

We demonstrate experimentally that the spectral sensitivity of an interferometer can be greatly enhanced by introducing a slow-light medium into it. The experimental results agree very well with theoretical predictions that the enhancement factor of the spectral sensitivity is equal to the group index n(g) of the slow-light medium.

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.

Slow-light interferometry: practical limitations to spectroscopic performance

Zhimin Shi, Robert W. Boyd

We investigate how the use of slow-light methods can enhance the performance of various types of spectroscopic interferometers under practical conditions. We show that, while in ideal cases the enhancement of the spectral resolution is equal to the magnitude of the group index of the slow-light medium, the ratio between the associated gain or loss and the group index of the slow-light medium actually determines the spectral resolution under more-general conditions. Moreover, the dispersion of this ratio leads to frequency-dependent spectral resolution, which limits the useful working bandwidth of the interferometer. We also evaluate the performance of interferometers using three specific slow-light processes in terms of the achievable spectral resolution and the effective working finesse. We show that the spectral resolution is typically limited by the characteristic linewidth of each slow-light process and that there is no fundamental upper limit for the effective working finesse.
