Abstract
Structures for an optical power splitter and methods of forming a structure for an optical power splitter. A first waveguide core provides an input port, and second and third waveguide cores provide respective output ports. A non-linear waveguide taper is coupled to the first waveguide core at a first interface and is coupled to the second and third waveguide cores at a second interface. The non-linear waveguide taper includes a first curved section having a first width dimension that increases with increasing longitudinal distance from the first interface. The non-linear waveguide taper includes a second curved section having a second width dimension that increases with increasing longitudinal distance from the second interface. The first and second curved sections join at a longitudinal location at which the first and second width dimensions are each equal to a maximum width of the non-linear waveguide taper.
