STABLE OPTICAL WAVEGUIDE AND METHOD OF MANUFACTURING THE SAME

原文（中文）

Some embodiments of the present disclosure are directed to an optical device including a stable optical waveguide loop and method of manufacturing the same. For example, an optical device (e.g., an optical ring resonator) may include a substrate and an optical waveguide loop formed on the substrate. The optical waveguide loop may define a path, where the optical waveguide loop may have an inner and outer radius that may be configured to be variable along the path of the optical waveguide loop. Further, a distance between the inner radius and a corresponding outer radius may define a width of the optical waveguide loop, where the width may be variable along the path of the optical waveguide loop. Additionally, or alternatively, the width may be configured to admit a plurality of higher order modes of light that may couple to a fundamental mode of light.
