Abstract :
We have studied THz detection performance of low-temperature-grown GaAs (LT-GaAs) photoconductive switches gated with 1560-nm-optical pulses. LT-GaAs is annealed in the range of 500-600degC. Although the sample annealed at 600degC is most sensitive at frequencies below 1 THz, that annealed at 550degC is superior to others at higher frequencies than 1 THz.
