Abstract
Several options for THz emitters and detectors operated at pump wavelengths around 1560 nm were investigated. Results from photoconductive antennas on In0.53Ga0.47As-based epilayers as well as DAST crystals are presented. Furthermore, the use of standard LTG GaAs antennas without frequency doubling is explored.
