Abstract
Optical devices and methods include a first waveguide having a first surface and a second waveguide including a second surface. The first waveguide is at a fixed position relative to the second waveguide with the first surface at least partly facing the second surface, and the first surface includes a first positioning element. The first positioning element is a NanoImprint Lithography (NIL) structure. The optical device further includes an adhesive arranged for attaching the first surface to the second surface, where the first positioning element is arranged to control a position of the adhesive. The first positioning element includes a philic region adapted to attract the adhesive, or a phobic region adapted to repel the adhesive.
