Abstract
A 1D nanobeam photonic crystal cavity is provided that includes a substrate, where the substrate includes a dielectric medium, and a series of cutout features in the substrate, where each cutout feature includes a first curved surface and a second curved surface, where the first curved surface and the second curved surface form a meniscus shape, where the series of cutout features include an array of sizes of the meniscus shape cutouts, where edges of the meniscus shape and the array of sizes are disposed to form a pair of opposing parabolic dips proximal to a central region of the series of cutout features.
