Disclosed is a photomixer which basically solves a present lamination element in a photomixer and a PCA which is a core part of an existing broadband tera hertz spectroscopy. The photomixer includes an active layer which is formed on the upper surface of a substrate and formed in one region where light enters, and a thermal conductive layer which is formed on the upper surface of a substrate and is formed in the other region. The active layer has a mesa-type cross section. The thermal conductive layer has a flat surface by regrowing the other region with a MOCVD method.
