Abstract

Abstract The direct photocurrent detection capability of light orbital angular momentum (OAM) has recently been realized with topological Weyl semimetals, but it is limited to the near‐infrared wavelength range. The extension of the direct OAM detection capability to the mid‐infrared band, which is a wave band that plays an important role in a vast range of applications, has not yet been realized. This is because the photocurrent responses of most photodetectors are neither sensitive to the phase information nor efficient in the mid‐infrared region. In this study, a photodetector based on the type‐II Weyl semimetal tantalum iridium telluride (TaIrTe4) is designed with peculiar electrode geometries to directly detect the topological charge of the OAM using the orbital photogalvanic effect (OPGE). The results indicate that the helical phase gradient of light can be distinguished by a current winding around the optical beam axis, with a magnitude proportional to its quantized OAM mode number. The topologically enhanced responses in the mid‐infrared region of TaIrTe4 further help overcome the low responsivity issues and finally render direct OAM detection capability. This study enables on‐chip‐integrated OAM detection, and thus OAM‐sensitive focal plane arrays in the mid‐infrared region.
