Abstract: The invention relates to a plasmonic device and a method for fabricating a plasmonic device. The plasmonic device comprises a substrate on which is arranged a plasmonic section which includes at least one inorganic confining structure adjacent to an organic optical material for providing a plasmonic waveguide. The organic optical material originates from one or more processes for arranging the organic optical material in a limited area. A protective layer is deposited for covering and/or enclosing the organic optical material for improved reliability of the plasmonic waveguide.

Abstract: A plasmonic device (1) for generating a modulated optical signal comprises: a substrate (2): a plasmonic section (3) which includes at least one confining structure (31, 32) and an optical material (33) for providing a plasmonic waveguide (34); and a heat dissipating section (4) thermally cooperating with the plasmonic waveguide (34) for dissipating heat from the plasmonic waveguide (34), wherein the plasmonic section (3) is configured to generate from an optical signal which is coupled into the plasmonic section (3) a modulated optical signal which is modulated in accordance with an electrical signal applied to the at least one confining structure (31, 32).
