(a) The interferogram generated by the homodyne detector reproduces the time-domain profile of the THz electric field. (b) Fourier transformed field, showing the multiple frequency components explicitly. (c) and (d) The same spectrum recorded with either of the laser beams removed.

FIG. 2.

Transmission spectrum of the THz photonic filter (illustrated inset). The pass band may be altered by mechanically shifting the plates, and is here shown tuned to transmit the components.

FIG. 3.

(a) Interferogram of the filtered THz signal, exhibiting the preserved THz carrier wave and amplitude modulation, but with the low-frequency oscillations removed. (b) The Fourier transformed data.
