Abstract
Structures for an optical coupler and methods of fabricating a structure for an optical coupler. The structure includes a first waveguide core having a first tapered section and a second waveguide core having a second tapered section positioned adjacent to the first tapered section of the first waveguide core. The second tapered section is positioned with a lateral offset in a lateral direction relative to the first tapered section. The second tapered section is positioned with a vertical offset in a vertical direction relative to the first tapered section.

A structure for an optical coupler, the structure comprising:
- a first waveguide core having a first tapered section;
- and
- a second waveguide core having a second tapered section positioned adjacent to the first tapered section of the first waveguide core, the second tapered section positioned with a first lateral offset in a lateral direction relative to the first tapered section, and the second tapered section positioned with a first vertical offset in a vertical direction relative to the first tapered section.
A method of forming a structure for an optical coupler, the method comprising:
- forming a first waveguide core that includes a first tapered section;
- and
- forming a second waveguide core that includes a second tapered section positioned adjacent to the first tapered section,
- wherein the second tapered section is positioned with a lateral offset in a lateral direction relative to the first tapered section of the first waveguide core, and the second tapered section is positioned with a vertical offset in a vertical direction relative to the first tapered section of the first waveguide core.
