Abstract
A photonic buried interposer for converting light between a first optical mode of a first optical component and a second optical mode of a second optical component, the second optical component being larger than the first optical component; the buried interposer comprising a bi-layer taper, the bi-layer taper comprising: a top device layer comprising an upper tapered waveguide; and a bottom device layer comprising a lower tapered waveguide; wherein the upper tapered waveguide extends from a first end for coupling to the first optical component to a second end for coupling to the second optical component; and the lower tapered waveguide starts from an intermediate location between the first and second ends and extends from the intermediate location to the second end.
