摘要： Provided is a method for manufacturing an optical component, including the following steps: producing at least one optical waveguide or a part of an optical waveguide on a substrate, where producing the optical waveguide or the part of the optical waveguide includes producing a waveguide core or a portion of a waveguide core, and where the waveguide core or the portion of the waveguide core includes silicon nitride, a polymer or a III-V semiconductor material; and arranging at least one layer of lithium niobate on a side of the waveguide core or of the portion of the waveguide core facing away from the substrate. After arranging at least one layer of lithium niobate at least one of the following steps is carried out: structuring at least one layer of lithium niobate, producing a further portion of the waveguide core and/or arranging at least one contact structure for electrically contacting the at least one layer of lithium niobate.
