Abstract:
A waveguide structure for optical coupling is provided. The waveguide structure includes a first waveguide embedded in a cladding of a lower refractive index than the first waveguide, a second waveguide of a higher refractive index than the cladding, and an intermediate waveguide. The first waveguide and the second waveguide are physically arranged at the same side of the intermediate waveguide to establish an optical coupling between the first waveguide and the second waveguide through the intermediate waveguide. The first waveguide material has a refractive index value smaller than or equal to 3.

Claim (Index 4):
The waveguide structure according to  claim 2 , wherein the intermediate waveguide has a thickness in the range of 200 nm to 500 nm, the first tapered end of the intermediate waveguide having a width less than 150 nm, and the second tapered end of the intermediate waveguide having a width in the range of 100 nm to 300 nm.
