摘要: Disclosed herein is a photomixer and method of manufacturing the photomixer which can fundamentally solve the existing restrictive factors of a PCA and a photomixer which are core parts of a conventional broadband terahertz spectroscopy system. The presented photomixer includes an active layer formed on a top surface of a substrate, the active layer being formed on an area on which light is incident, and a thermal conductive layer formed on the top surface of the substrate, the thermal conductive layer being formed on an area other than the area on which light is incident. The active layer is formed to have a mesa cross section, and the thermal conductive layer is regrown on an area other than the area on which light is incident using an MOCVD method, and has a flattened surface.
