Abstract

We report a novel porous-core octagonal photonic crystal fiber (POPCF) for practical low-loss terahertz (THz) wave guiding. The POPCF with a porous core surrounded by an air-hole cladding shows a low material absorption loss of ~0.07 cm^-1, or one third of that for the bulk material absorption loss at the operating frequency ~1 THz. In addition, the confinement loss, bending loss, and effective modal area properties of the POPCF are also reported and demonstrated to be relatively low. The proposed POPCF has potential applications for efficient transmission of broadband THz radiation.
