Abstract :
We present a continuous-wave coherent homodyne detection system based on terahertz (THz) phase control using balanced electro-optic phase modulation for high dynamic range. Phase-sensitive and fast THz measurement is demonstrated with a dynamic range of over 55 dB in 1-ms integration time.
