According to embodiments of the present invention, a photodetector is provided. The photodetector includes a substrate, a waveguide formed on a surface of the substrate, a first metal layer formed on a first side of the waveguide, wherein a first interface is defined between the waveguide and the first metal layer, and a silicide layer formed on a second side of the waveguide, wherein a second interface is defined between the waveguide and the silicide layer, and wherein the second side is opposite to the first side, and wherein at least one of the first interface and the second interface is at least substantially perpendicular to the surface of the substrate. Various embodiments further provide a method of forming the photodetector.
