Abstract: Provided is a photon detector. The photon detector includes an optical waveguide including input and detection regions, which are spaced apart from each other in a first direction, and a conversion region between the input region and the detection region, a nano pattern disposed on the optical waveguide in the conversion region, and a nanowire disposed on the optical waveguide in the detection region. The nano pattern includes a first pattern and a second pattern, which extend in the first direction, and the first pattern and the second pattern are spaced apart from each other in a second direction crossing the first direction.
