A novel design of an optically pumped THz photoconductive source in array configuration is presented. The proposed solution is based on the exploitation of the ultrawide band properties of connected antenna arrays. The photoconductive elements of the array are excited by an array of microlenses which splits and focuses the laser beam onto the active areas of the connected array. An ad-hoc DC biasing...
Terahertz remote sensing, transmission of terahertz radiation for communication, and other applications which require transport of terahertz radiation at a distance permanently attract great attention. Security, spectroscopy, lidar techniques, and data transmission are areas of interest. Depending on the goals and the environment (atmosphere or space), in different applications the word “remote” can...
