Abstract: A method of manufacturing a film assembly comprises forming a film-based lightguide with a lightguide region, adding a layer comprising linear light turning features to the film-based lightguide while it is moving in a web direction such that the linear light turning features are oriented in the web direction of the film-based lightguide, and cutting the film-based lightguide while it is moving in a web direction in a plurality of linear sections, the plurality of linear sections comprises linear sections that define lateral edges a light emitting region and/or lateral edges of coupling lightguides extending from the lightguide region, wherein the linear sections are cut at first cut angle between 3 degrees and 25 degrees to a transverse direction of the film-based lightguide orthogonal to the web direction and the thickness direction.

Abstract: Waveguide structure for propagating a surface plasmon polariton, including an inter-metal plasmonic waveguide (1). The waveguide structure has two metal strip like structures (2, 3) positioned parallel to each other and an isolating material structure (4) positioned between the two metal strip like structures (2, 3). The two metal strip like structures (2, 3) are positioned at a fixed distance (d) from each other. The inter-metal plasmonic waveguide (1) is provided in a single layer of a CMOS processed substrate (5). Several waveguide structures (1) may be combined with a crystal like structure (6) to build logic gates, such as a switch having a gate, source and drain terminal (1G, 1S, 1D). Using three dimensional designs spanning several layers in a CMOS processed substrate (5) very complex yet compact logic circuits may be designed.
