Abstract
An optical arrangement includes a plurality of planar substrates with at least one planar integrated optical waveguide on each planar substrate. At least one optical waveguide structure has at least one end connected via an optical connecting structure to one of the planar integrated optical waveguides. The optical waveguide structure is positioned at least partly outside the integration plane for the planar integrated optical waveguide and a refractive index contrast between a core region and a cladding region of the optical waveguide structure is at least 0.01.
