Interferometers have wide applications in modern interferometry, physical geography, bioengineering and signal processing of quantum. And a higher performance of it is badly needed. By numerical simulation we prove that the sensitivity of interferometer could be enhanced effectively by dispersive property of the slow light medium. And the sensitivity is proportional to the group refractive index of slow light medium. The investigation gives the general method of designing slow light interferometer taking into account the dispersive property of GaAs.
