Abstract :
We present a fiber-based 2-port THz electro-optic sampling system at 1.55 mum wavelength, including an ultrafast In0.53Ga0.47As photoconductive switch and a freely positionable prismatic electro-optic probe. Frequency components are extended up to 2 THz and the dynamic range is larger than 40 dB regardless of the direction of the electromagnetic wave propagating in the waveguide thanks to the 2-port system. The symmetrical 2-port pigtailed electro-optic probe allows to determine the direction of propagation of the guided picosecond electromagnetic pulses.
