摘要

We develop a technique based on a micromachined photoconductive probe-tip to characterize a terahertz (THz) porous fiber. Losses less than 0.08 cm~(-1) are measured in the frequency range from 0.2 to 0.35 THz, with the minimum of 0.003 cm~(-1) at 0.24 THz. Normalized group velocity greater than 0.8, which corresponds to dispersion values in between —1.3 and -0.5 ps/m/μm for 0.2
