摘要

We present recent developments of two kinds of compact room-temperature detectors for terahertz radiation. These areasymmetrically-shaped bow-tie diodes, and field-effect transistors with sub-micrometer channel lengths. Both kinds ofdetectors exhibit fast response times which allow operating them as mixers, moreover they are suitable for the fabricationof large multi-pixel arrays. Here, we provide data on the experimental performance of detector arrays and show theirapplicability in coherent terahertz imaging systems. In addition, we demonstrate real-time operation of a 12×12-pixelCMOS camera in power-detection mode at 590 GHz.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
