Patent ID: 8802481

Claim:
A method to assemble a photodetector capable to detect visible light spectrum, the method comprising: providing a source and a drain; coupling the source and the drain with at least one nano-assembly; positioning at least two surface plasmon waveguides between the source and the drain and juxtaposing to the at least one nano-assembly in a longitudinal direction of the at least one nano-assembly; positioning a transparent gate in proximity to the at least one nano-assembly and the at least two surface plasmon waveguides; and arranging the transparent gate so as to extend substantially parallel to at least one of the source and the drain, wherein one of the at least two surface plasmon waveguides is positioned along a first side of the at least one nano-assembly, and another of the at least two surface plasmon waveguides is positioned along a second side of the at least one nano-assembly that is opposite the first side.
