Abstract
Embodiments of the invention describe a skew directional coupler for a plurality of waveguides. Said coupler includes a first waveguide on a first plane and a second waveguide on a second plane separate from the first plane. In embodiments of the invention, the first waveguide is disposed on top of the second waveguide to form an overlapping region of a segment of the first waveguide and a segment of the second waveguide, wherein an optical axis of the segment of the first waveguide is horizontally skew to an optical axis of the segment of the second waveguide, and wherein light is to be passively transmitted between the first and second waveguide segments via mode hybridization.

An apparatus comprising:
- a first waveguide on a first plane;
- and
- a second waveguide on a second plane separate from the first plane;
- wherein the first waveguide is disposed on top of the second waveguide to form an overlapping region of a segment of the first waveguide and a segment of the second waveguide, wherein an optical axis of the segment of the first waveguide in the overlapping region is horizontally skew to an optical axis of the segment of the second waveguide in the overlapping region, and wherein light is to be passively transmitted between the first and second waveguide segments via mode hybridization in the overlapping region.
A method comprising:
- forming a first waveguide on a first substrate;
- forming a second waveguide on a second substrate;
- and
- placing the first substrate on to the second substrate to form an overlapping region of a segment of the first waveguide and a segment of the second waveguide, wherein an optical axis of the segment of the first waveguide segment in the overlapping region is horizontally skew to an optical axis of the segment of the second waveguide segment in the overlapping region for light to be passively transmitted between the first and second waveguide segments via mode hybridization in the overlapping region.
