Claim 0:
1. A device coupon for use in a hybrid integration process with a silicon platform, the device coupon comprising:
an input waveguide, including an input facet;
an active waveguide, coupled to the input waveguide, the active waveguide including a III-V semiconductor based electro-optical device; and
an output waveguide, configured to couple light between the active waveguide and an output facet,
wherein the input waveguide and output waveguide are passive waveguides, and
wherein a waveguide from among the input and output waveguides contains a bend, and a width of the bend, in a direction parallel to a plane of a top surface of the waveguide containing the bend, is less than a width of the active waveguide in a direction parallel to the plane.
