OPTICAL MICRORESONATOR WITH MICROCYLINDER AND CIRCUMFERENTIAL COATING FORMING RESONANT WAVESGUIDES

摘要

An optical microresonator and method of forming same includes a microcylinder and a circumferential coating formed on the microcylinder. This coating has a higher index of refraction than the microcylinder and is of such thickness relative to the diameter of the microcylinder that a resonant waveguide is formed such that light optically couples from an optical source waveguide onto the microcylinder.
