Abstract
Low-temperature-grown GaAs photoconductive antenna was investigated as the detector of THz pulses for 1560 nm excitation. A S/N value higher than 50 dB obtained with a standard measurement condition suggests that the antenna can be used as a detector in 1560 nm-based commercial time domain systems.
