Waveguide dispersion effects in silicon-on-insulator coupled-resonator optical waveguides

Opt Lett. 2010 Sep 15;35(18):3030-2. doi: 10.1364/OL.35.003030.

Abstract

The dispersion of the waveguides that constitute microring resonators can considerably affect the dispersion characteristics of coupled-resonator optical waveguides (CROWs). We derive expressions for CROW dispersion and group delay for silicon-on-insulator microring CROWs, showing both theoretically and experimentally the band-to-band dependence of the bandwidth and group delay on the dispersion properties of the constituent single-mode silicon waveguide.
