Abstract :
The terahertz wave was generated by photoconductive antenna (PCA) based on low-temperature grown (LTG)GaAs with 1550nm pulse excitation. We constructed terahertz time domain spectroscopy (THz-TDS) system by all 1550nm band excitation and obtained the spectrum of terahertz wave in the range to 2THz.
