摘　　要：设计了一种基于慢光介质色散特性的新型干涉装置,研究其物理过程,证明利用慢光介质可以有效提高干涉仪的光谱灵敏度,并且光谱灵敏度与慢光介质的群折射率成正比。同时,进一步具体分析慢光介质GaAs的色散特性,给出研究色散型慢光干涉仪的一般性方法,并证明使用慢光介质GaAs在近红外区域可以提高光谱灵敏度2倍左右。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.
