Abstract: An example embodiment may include an optical system for obtaining radiation coupling between two waveguides positioned in a non-coplanar configuration. The optical system may include a first waveguide positioned in a first plane and a second waveguide positioned in a second plane. The first waveguide may be stacked over the second waveguide at a distance adapted to allow evanescent coupling between the first waveguide and the second waveguide. The first waveguide and the second waveguide may be configured such that the coupling is at least partly tolerant to relative translation or rotation of the first waveguide and the second waveguide with respect to each other.

Abstract: Example embodiments relate to multilevel coupling for phase front engineering. An example integrated optical structure for phase front engineering of optical beams includes a substrate. The integrated optical structure also includes a plurality of optical layers formed on the substrate. Each of the optical layers includes an optical phased array that includes a plurality of optical waveguides. Each of the optical layers also includes a coupling section for each of the optical waveguides. Each coupling section is configured to control the phase of an optical beam coupling out of the optical waveguide. Additionally, the integrated optical structure includes a slab waveguide formed on the substrate and between two of the optical layers. The slab waveguide is in optical communication with the coupling sections of the two optical layers. The slab waveguide includes a slab waveguide outcoupling structure.

Abstract: A sensor comprises: a thin structure, which is configured to receive a force for deforming a shape of the thin structure and which is arranged above a substrate; and a waveguide for guiding an electro-magnetic wave comprising: a first waveguide part; and a second waveguide part; wherein the second waveguide part has a larger width than the first waveguide part; and wherein the first and the second waveguide parts are spaced apart by a gap which is sufficiently small such that the first and second waveguide parts unitely form a single waveguide, wherein one of the first and the second waveguide part is arranged at least partly on the thin structure and another of the first and the second waveguide part is arranged on the substrate.
