| Abstract(in English) | Asymmetric-dual-grating-gate high-electron-mobility-transistors (ADGG-HEMTs) are expected for room-temperature operating, high-speed THz detectors. However, their low light receiving efficiency is one of serious concerns because the focused spot size of free space THz wave is much smaller than the active area of ADGG-HEMTs. To improve this, we examine 1) increasing the effective active area by implementing series array of detectors and 2) shrinking the spot size by integrating a detector with a hyper-hemispherical silicon lens. We report the 4-fold enhancement of responsivity by series array of 4 detectors and the 6-fold enhancement by the silicon lens integration. Also, we discuss the frequency characteristics on silicon lens module. |
