Abstract

Structures for a waveguide bend and methods of fabricating a structure for a waveguide bend. A waveguide core has a first section, a second section, and a waveguide bend con necting the first section with the second section. The wave guide core includes a first side surface and a second side surface, the first side surface extends about an inner radius of the waveguide bend, and the second side surface extends about an outer radius of the waveguide bend. The waveguide bend includes a central region and a side region that is arranged adjacent to the central region at the first side surface or the second side surface. The central region has a first thickness, and the side region has a second thickness that is less than the first thickness.
