Abstract :
We present the generation of a terahertz pulse train from a rectangular GaP waveguide emitter pumped by a compact photonic crystal fiber femtosecond amplifier. The effects of the pump pulse width and chirp characteristics on the terahertz conversion efficiency and the generated THz spectrum were studied. The peak spectrum could be easily tuned by altering the separation of the compression grating pair.
