  • Abstract
    We show that recently-demonstrated ldquomagic widthrdquo designs to mitigate TM-like mode radiation losses in high-index-contrast SOI ridge waveguides are significantly impacted by waveguide curvature and coupling elements, requiring additional care in designing high-Q SOI photonics.
