Waveguide Implementations With Adiabatic Structures

Abstract: optical waveguides with adiabatic bends (e.g., hybrid partial euler bends) are described herein. the optical waveguides are implemented into various optical components of integrated photonic devices to improve the performance of the optical components and allow for more compact manufacturing of the integrated photonic devices. in one example, a waveguide having a geometric path defined in a plane and a width perpendicular to the geometric path is described. the geometric path includes an adiabatic curve connecting a first inflection point to a second inflection point on the geometric path, the adiabatic curve including: a circular arc subtending an angle from a first endpoint to a second endpoint; a clothoid connecting the first inflection point to the first endpoint of the circular arc; and an anti-clothoid connecting the second endpoint of the circular arc to the second inflection point.
