Abstract
In part, the disclosure relates to an optical coupler. The optical coupler may include two ridge waveguides that include a first waveguide and a second waveguide. One or more segments of the two waveguides extend over a coupling length or other distance. One or more sections of each ridge waveguide is at least partially defined by a set of cross-sectional profiles, a plurality of sections of each ridge waveguide have a width that tapers along a length of the two ridge waveguides. Within the coupling length, a subset of the set of cross-sectional profiles may define a first pair of transition regions and a second pair of transition regions. The coupler may include a coupling region between the two ridge waveguides and spanning at least a section of the coupling length.
