Abstract

We report on an all-fiber terahertz (THz) radiation source by exploiting nonlinear parametric process in a theoretically designed microstructured-core double-clad plastic fiber (MC-DCPF). The required phase-matching condition is satisfied through suitable tailoring of the fiber dispersion and nonlinear properties at the pump wavelength of a high-power CO2 laser, with a CO laser of much lower power acting as a seed concomitantly. Our simulated results reveal that a THz radiation source at the frequency of 3THz could be realized with a 3-dB phase-matching band width of 2.13 GHz in a 65-m-long optimized MC-DCPF. Maximum power conversion efficiency >1% is realizable even after including the material loss.
