A terahertz (THz)‐wave interferometer was devised for measurement of the THz‐wave phase shift. In this measurement system, the relative phase shift is deduced from the interference between the THz waves generated by two photomixers. Experimental results with this interferometer revealed that the semiconductor phase modulator could be used as a THz‐wave phase shifter by utilising its chromatic dispersion.
