We demonstrate picosecond terahertz (THz)-wave generation via four-wave mixing in an octagonal photonic crystal fiber (O-PCF). Perfect phase-matching is obtained at the pump wavelength of 1.55 μm and a generation scheme is proposed. Using this method, THz waves can be generated in the frequency range of 7.07 7.74 THz . Moreover, peak power of 2.55 W , average power of 1.53 mW , and peak conversion efficiency of more than 66.65 dB at 7.42 THz in a 6.25 cm long fiber are realized with a pump peak power of 2 kW .
