A terahertz (THz) cross-correlation device for material characterization of a sample comprising an optical source for outputting a continuous-wave (CW) optical signal; THz antennas providing a THz transmitter and a THz receiver optically coupled to the optical source, and an optical delay setup configured to adjust a synchronization of the THz receiver to the THz transmitter by the CW optical signal. The optical source is configured to provide a CW optical signal having an at least substantially continuous broadband spectrum and the optical paths for the CW signal are provided by optical waveguides such as optical fibres or integrated waveguides. The optical delay setup comprises a double-pass polarization-conserving fibre stretcher comprising a circulator, a fibre stretcher, and a Faraday mirror; and/or a variable solid state optical delay (SSOD).
