Analysis and simulation of ring resonators for slow and fast light devices applications

Abstract

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.
