Paper Abstract

We propose a porous-core octagonal photonic crystal fiber for low-loss terahertz (THz) waveguiding. Great attention is given to the geometries of the fiber inside the core to increase the fraction of power transmitted through the air holes. At an operating frequency f=1  THz, this design exhibits a low effective material loss which is approximately 0.05  cm1 or 0.2  dB/cm. In addition to the confinement loss, some other properties like the power fraction of the core air holes, responses of the effective material loss, and power fraction with respect to frequency have been also reported. This design is useful for efficient transmission of broadband terahertz radiation.
