| 摘要 |
An apparatus, including an optical ring resonator having a waveguide ring with substantially straight waveguide segments and bent waveguide segments. The bent waveguide segments are optically coupled to the substantially straight waveguide segments and have optical cores with substantially smaller cross-sectional areas than the substantially straight waveguide segments. The bent waveguide segments change a propagation direction of received light by more than ½ of a right angle.
