Abstract

Structures for a waveguide bend and methods of fabricating a structure for a waveguide bend. A first waveguide core has a first section, a second section, and a first waveguide bend connecting the first section with the second section. The first waveguide core has a first side surface extending about an outer radius of the first waveguide bend. A second waveguide core also has a first section, a second section, and a second waveguide bend connecting the first section with the second section. The second waveguide core has a second side surface extending about an outer radius of the second waveguide bend. The first waveguide bend is spaced from the second waveguide bend in a first non-contacting relationship with a gap between the first side surface and the second side surface. The gap has a perpendicular distance selected to permit optical signal transfer between the first and second waveguide bends.
