  • Abstract
    We present a compact and stable continuous-wave terahertz spectroscopic system with a planar lightwave circuit-LiNbO3 phase modulator for terahertz phase control. Thanks to significantly shortened optical paths with temperature control, the system enables fast vector measurement with effective phase stabilization. The phase stability of 2° was obtained over a period of 2 h.
