Abstract: Provided is a waveguide photodetector that may improve an operation speed and increase or maximize productivity. The waveguide photodetector includes a waveguide layer extending in a first direction, an absorption layer disposed on the waveguide layer, a first electrode disposed on the absorption layer, a second electrode disposed on the waveguide layer, the second electrode being spaced from the first electrode and the absorption layer in a second direction crossing the first direction, and at least one bridge electrically connecting the absorption layer to the second electrode.
