Abstract

An hollow-core terahertz fiber applying anti-resonant Bragg structure as the basic unit is proposed. Simulations results shown that the proposed THz fiber shows both the transmission characteristics of a conventional anti-resonant structure and a Bragg fiber. The confinement loss of which could be two-three orders of magnitude lower than that of an anti-resonant structure fiber consists of a single anti-resonant ring, and the total loss is one order of magnitude lower, the transmission loss of the proposed THz fiber could be 0.5 dB/m or less with a relative wide bandwidth of 0.15 THz.
