Abstract
A strip-loaded optical waveguide includes a slab layer, a strip layer, and a cladding region. The slab layer has a first optical refractive index and a first width measured in a transverse direction that is perpendicular to a light propagation direction through the strip-loaded optical waveguide. The strip layer is disposed above the slab layer. The strip layer has a second optical refractive index and a second width as measured the transverse direction. The second width is less than the first width of the slab layer. The second optical refractive index is less than the first optical refractive index of the slab layer. The cladding region is disposed above the slab layer and above the strip layer. The cladding region has a third optical refractive index that is less than the second optical refractive index of the strip layer.
