FIG. 1.

Schematic of the THz time-domain spectroscopy setup employed for characterization of porous fibers. Two parabolic mirrors and a metallic cone are employed to couple the THz pulses into the waveguide. The emitter and detector are shown in the inset.

FIG. 2.

(a) Absorption coefficient, , and (b) effective refractive index of the propagating fundamental mode in a COC spider-web porous fiber: black dots and red dashed lines represent the measured and theoretical values, respectively. The fiber cross-section and group velocity are shown in the inset of parts (a) and (b), respectively.

Image of FIG. 3.
FIG. 3.

Measured radial field distribution from the waveguide interface at 0.23 THz (top dotted line), and 0.28 THz (bottom dotted line). The solid lines represent the theoretical values (for a diameter real porous fiber) of normalized radial distribution of -component of the electric fields.
