Abstract-A novel low loss porous-core photonic crystal fiber for terahertz wave transmission
http://ieeexplore.ieee.org/document/7912878/ A novel low loss porous core photonic crystal fiber (PCF) is proposed in this paper for terahertz (THz) wave propagation. In order to investigate the guiding properties and numerical simulations, finite element method based COMSOL v4.2 software is used. Only circular air holes are used in this proposed structure so the design is easy to realize and fabricate. The numerical analysis confirms that, the proposed microstructure fiber exhibits low effective material loss of 0.063 cm-1 at 1.0 THz operating frequency. Moreover, a low confinement loss of 6.9 × 10-3 cm-1 and low bending loss of 1.07 × 10-11 cm-1 is obtained for the optimum designing condition at an operating frequency of 1.0 THz. The other guiding properties such as power fraction, effective area and dispersion are also discussed in this paper.
