Abstract: Disclosed is a plasmonic device (10), comprising: a substrate (11); and a dielectric layer (13) arranged between a base metal layer (12) and a structured metal layer (14) which form with respect to the substrate (11) a vertical stack of layers, wherein the structured metal layer (14) includes arranged in a horizontal direction an input structure (141) for enabling an input section (21), a waveguide structure (142) for enabling a plasmonic waveguide (22), and an output structure (143) for enabling an output section (23), wherein the input section (21) is configured to receive an optical input signal (31) and transmit input power (41) to the plasmonic waveguide (22), wherein the plasmonic waveguide (22) is configured to receive input power (41) from the input section (21) and transmit output power (43) to the output section (23), and wherein the output section (23) is configured to receive output power (43) from the plasmonic waveguide (22) and transmit an optical output signal (33).
