We investigate the propagation properties in microspheres coupled with a fiber taper system. The resonant properties display the properties of coupled resonator induced transparency and coupled resonator induced absorption. The transmission amplitudes for the various cases are compared and analyzed in the complex plane. Our results indicate that the switch between superluminal and subluminal light propagation can be realized by doping the gain medium in the multiple microspheric resonators.
