S. Kono et al., Detection of up to 20 THz with a low-temperature-grown GaAs photoconductive antenna gated with 15 fs light pulses, APPL PHYS L, 77(25), 2000, pp. 4104-4106
We report on the ultrabroadband coherent detection of radiation in waveleng
ths spanning from far to midinfrared with a low-temperature-grown GaAs phot
oconductive dipole antenna gated with 15 fs light pulses. The detected spec
tral frequency exceeds 20 THz. (C) 2000 American Institute of Physics. [S00
