Abstract

A side coupled adjacent resonators CROW (SC-CROW) structure is presented. The dispersion relation, group velocity and GVD are found numerically and analytically using a transfer matrix method. The structure shows fast and slow transmission of light. Zero group velocity is present at the ends of the Brillouin zone, but also in other parts of it. Infinite and finite SC-CROW structures show band gaps created by Bragg and ring resonances. Pulse propagation at slow group velocities is highly dispersive, but easier to manage at higher group velocities. The differences between SC-CROW, SCISSOR and CROW waveguides are studied in detail.
