title = "Mode-expanded bus architecture for non-sensitive waveguide alignment in vertically-coupled microring",
abstract = "We demonstrate experimentally a five-fold improvement in fabrication tolerance for vertically-coupled microrings using a mode-expanded bus waveguide. The power coupling coefficient is observed to vary by only 6% for misalignment as high as 1μm.",
