FIG. 1.

Experimental setup for the generation and characterization of THz signal. All fiberised and free space components operate at room temperature. Optical fiber is represented with a solid line and electrical path is represented with dashed line.

FIG. 2.

THz spectrum recorded for the DUT biased at 88.5 mA and temperature controlled at . Measured data are represented by (○), the fitted Lorentzian distribution is represented by a solid line. In inset the optical spectrum recorded with a resolution of 0.02 nm, for the same bias and temperature conditions of the DUT.
