Abstract:
Structures for an optical coupler and methods of fabricating a structure for an optical coupler. A first waveguide core has a first tapered section and a second waveguide core has a second tapered section positioned adjacent to the first tapered section. The first tapered section has a first shape determined by a first non-linear function, and the second tapered section has a second shape determined by a second non-linear function.
