Abstract:
1. An optical waveguide assembly, comprising a first optical waveguide and a second optical waveguide wherein the first optical waveguide is a gradient-step waveguide having a waveguide numerical aperture based on a waveguide core dimension and a waveguide core refractive index gradient, and having a refractive index step at a core/cladding boundary such that n B √{square root over (2Δ 1 )}≧0.04, wherein n B is a refractive index within the waveguide at the core/cladding boundary, and n CLAD is a cladding refractive index, wherein the first and second waveguides having respective independently positionable first and second input portions that extend into a bundled waveguide portion that defines an output surface operable to provide optical power received from the first and second input portions of the first and second waveguides, respectively.
