We generated frequency-tunable terahertz (THz) waves with stable carrier-envelope phases (CEPs) by exciting a photoconductive antenna with intensity-modulated laser pulses. The modulation of a laser pulse by using a birefringent crystal and a grating pair produced two chirped laser pulses with a fixed time separation, or in other words, an intensity-modulated laser pulse. The stability of the CEP of the THz waves was governed by the stability of the time separation of the two laser pulses generated by the birefringent crystal. Because the crystal thickness was fixed, the CEP of the THz wave was stable and not affected by the mechanical vibration of the optical components. We also demonstrated the CEP control of the THz wave.
