Abstract

The present invention provides a waveguide structure for optical coupling. The waveguide structure includes a first waveguide embedded in a cladding of lower refractive index than the first waveguide, and a second waveguide of higher refractive index than the cladding and distanced from the first waveguide. The waveguide structure further includes an intermediate waveguide, of which at least a part is arranged between the first waveguide and the second waveguide. The first waveguide and the second waveguide each comprise a tapered end for coupling light into and/or out of the intermediate waveguide.
