Increasing the delay-time--bandwidth product for microring resonator structures by varying the optical ring resonances.
We propose a scheme to increase the delay-time--bandwidth product for a periodic microring resonator structure in slowing or stopping light. The idea is based on the existence of a low group velocity and low dispersion region close to a band edge near a ring resonance. By putting different frequency components on resonance with different rings, one can drastically slow down the light without inducing large additional dispersive distortion.
