… Using full three-dimensional numerical modeling, we have shown recently that coupled
periodic optical waveguides in the silicon-on-insulator material system can exhibit a
degenerate band edge if the number of periods is sufficiently large [2]. In this paper, we
demonstrate experimentally quality factor scaling to the fifth power in fabricated periodic
silicon optical waveguides designed to exhibit a degenerate band edge. Measurements
show a clear transition of the … In summary, we demonstrate quality factor scaling to the …
We observe experimentally a transition of quality factor scaling from third power to fifth power of the number of periods in periodic silicon optical waveguides designed to exhibit a degenerate band edge.
