分析了光学材料的正常色散与反常色散特性, 证明了基于光学材料色散特性的干涉仪可以实现慢光与快光的结合。理论分析了基于快慢光技术的Mach-Zehnder(M-Z)干涉仪的光谱灵敏度, 与具有相同结构的传统M-Z干涉仪和仅依赖于慢光技术的M-Z干涉仪相比, 基于快慢光技术的M-Z干涉仪的光谱灵敏度大幅提升。

We analyze the normal and anomalous dispersion characteristics of optical materials, and prove that a kind of interferometer based on dispersion characteristics of optical materials can realize the combination of superluminal light and slow light. We also theoretically analyze the spectral sensitivity of Mach-Zehnder (M-Z) interferometer based on superluminal and slow light technology. Compared with the conventional M-Z interferometer which has the same structure with the above interferometer and the M-Z interferometer based on slow light technology, the spectral sensitivity of the M-Z interferometer based on superluminal and slow light technology increases sharply.
