In this paper we demonstrate, how fast and slow light phenomena in ring resonator can simultaneously be observed at a single frequency, using strongly coupled ring resonators. We also report on the design of a ring resonator with SOI technology that operate in optical wavelength 1.55 micron and have (one micro-ring) a factor for fast light ~22 picosecond (ps) and a factor for slow light ~12 ps with bandwidth ~100GHz with mixing angle (θ) 30 degrees, however depended on mixing angle and number of rings. Using light in a mixed polarization state, we show that fast and slow light can be obtained from a single incident wave packet. We simulate one micro-ring and extend our result to more micro-ring.
