AbstractA novel photonic crystal fiber (PCF) based on TOPAS, consisting only rectangular slots is presented and analyzed in this paper. The PCF promises not only an extremely low effective material loss (EML) but also a flattened dispersion over a broad frequency range. The modal characteristics of the proposed fiber have been thoroughly investigated using finite element method. The fiber confirms a low EML of 0.009 to 0.01 cm−1 in the frequency range of 0.77–1.05 THz and a flattened dispersion of 0.22±0.01 ps/THz/cm. Besides, some other significant characteristics like birefringence, single mode operation and confinement loss have also been inspected. The simplicity of the fiber makes it easily realizable using the existing fabrication technologies. Thus it is anticipated that the new fiber has the potential to ensure polarization preserving transmission of terahertz signals and to serve as an efficient medium in the terahertz frequency range.

Abstract A newer and efficient solid core with air holes and ring based circular photonic crystal fiber (C-PCF) design is proposed, developed, and studied. The C-PCF structure with a ring core and three layers of air holes is developed to communicate terahertz frequency of the range of 1 THz to 3 THz. Finite element method (FEM) is used to optimize the position, shape and dimensions of air holes and refractive index (RI) of material for the proposed PCF design and check the efficiency to support different orbital angular momentum (OAM) modes for communication. Our novel designed C-PCF supports multiple stable modes with mode purity above 0.9. Confinement loss is in the range of 10-12 dB/cm, highest effective mode area in the order of 1 mm2 is achieved in the investigated study for 3 THz transmission. The study observes that the performance of PCF is strongly dependent on RI of core and cladding.
