Abstract
Increasing applications of terahertz (THz) waves require design and fabrication of new waveguides with low transmission loss in THz region (0.1 ∼10 THz). Hollow-core photonic crystal fibers (HC-PCFs) with their unique characteristics hold great promise for efficient THz transmission. Hence, in this article, HC-PCFs are designed and simulated based on the finite-difference-time-domain (FDTD) method to efficiently transmit THz radiation. Impacts of structural parameters such as background material, core diameter, air-hole rings and filling factor on the THz transmission window of HC-PCFs are investigated. The results show that as the number of air-hole rings and the core diameter are increased the transmission loss is decreased. Also, the suitable HC-PCF in the transmission window of 1.55–1.85 THz with simultaneously good dispersion properties is obtained when the background material is Teflon.
